Nancy.

I think your husband has astigmatism. Sometimes I can't see one letter on a line but can read some letters on smaller line. It's because I have astigmatism.

I've also had the pinhole test which just checks central vision which is where we see most clearly.


antonio 24 Feb 2017, 10:20

Nancy, maybe your Husband is shortsighted? Could you read those numbers he couldn.t?

Even shortsighted people with otherwise healthy eyes can read far ok through pinhole glasses if there is enough light around, not in dimmed light of course.

So that might have been a test his eyes are not astigmatic or so. Hope that helps. I guess he will get glasses ?

Best regards, Antonio

Flashing Lights can trigger Migršne

Is that the case with your wife?

Maybe stress can too?

It normally gets better when she ages :-)

Best regards, antonio

My husband went for an eye exam and for the first time I went with him. Two questions...

When they had him read the lines on the wall. She put a line of print on the wall and he got the first 3 way wrong, and the second 3 letters perfect. She changed the letters, making them a bit smaller, and the same thing happened...3 way wrong and 3 right. I think this happened a 3rd time too. Why did that happen?

There was a line where he couldn't read any of the letters, and he was give a thing to hold that had small like pinholes on it, and tried that with each eye, and could read the lines perfectly. What difference did the pinholes make.

Thanks

My wife gets Migraine headaches with Aura. These type of migraine's can really scare you because she will lose peripheral vision, have blurred vision, or see things wavy. I am posting here to see if any one has any theories or experience with these and what might be possible causes. The doctors don't seem to have any idea what triggers these. The vision issues typically last less than an hour, followed by an extreme headache behind her eyes.


 05 Feb 2017, 10:02

N, your eyes can be helped with glasses, but you need glasses prescibed specifically for your eye condition. You should go to the optometrist and take an eye test, that is the only way to obtain the specific prescription you need.


N 05 Feb 2017, 09:39

i stay away from trying my friends glasses because it makes me nervous i will see better. i have tried wearing used glasses without anyone around. i was very scared to buy them because the cashier must know i need glasses or i would not buy them. i see much better but the bends do not change. maybe my eyes can't be helped with glasses. i don't understand why things are bending more than when i was younger.


 04 Feb 2017, 14:37

N,

Besides myopia and hyperopia (being nearsighted or farsighted), there are a few more visual conditions. Astigmatism is one of them, and can be corrected by glasses or contacts, so don't worry.


Cactus Jack 04 Feb 2017, 12:20

N,

Astigmatism is NOT a disease. It is usually caused by a slighty misshapen Cornea. We don't know the exact cause, but it seems to be caused by uneven growth of the eyeball that puts some stress on the Cornea.

The ideal shape of the Cornea is like a slice from the side of a perfect glass ball. A Cornea with Astigmatism is shaped like a slice from the side of a glass American Football where the curvature of the Cornea is steeper in one direction than it is in the other.

C.


N 04 Feb 2017, 09:57

can you explain to me what astmatism is? is it like a disease thing? i don't think i ever had it before. i see hard at night too. maybe it is because of this disease.


Cactus Jack 03 Feb 2017, 15:08

N,

You don't need a psychiatrist. It is very likely that you need vision correction and the place to start is an Optometrist or Ophthalmologist for an eye exam. If you have never had an eye exam, you may find the article I wrote "How to Study for an Eye Exam", helpful.

Vision actually occurs in the brain. Your eyes are merely Biological Cameras. Your brain can actually correct small vision problems, but it takes a lot of work and energy. The best thing is to correct the problem optically, if possible. There is nothing to be gained by delaying.

C,


antonio 03 Feb 2017, 14:48

N, and there are simple lenses in blasses to correct it. No mental illness at all.

Besteht regards. Antonio


 03 Feb 2017, 13:30

N, from what you're describing, looks like you have some astigmatism


N 03 Feb 2017, 13:17

I need help to understand my eyes. I can't see very far because it is blurry. I know that makes me nearsighted. But i am afraid to talk about it because I have another problem. I don't see straight lines. When I look ath this monitor in front of me, it bends toward the middle and it curves toward me on the end. I have the same problem with lamps, doorways, any long lines. they look bent. I am afraid maybe i am going crazy so i do not want to go to the doctor and say this. i tell friends i like that tv because it curves around you. they laugh and say it is straight. i get scared and embarased because that is how i see it. but i pretend to see it their way. do i need mental help? i am tired of my friends laughing


Soundmanpt 03 Feb 2017, 10:30

Sue

Unfortunately the store you bought your glasses from is one that doesn't stock anything weaker than +1.25 glasses. many stores do stock +1.00's which would have been slightly better to test your eyes with. But even only wearing your glasses for about an hour while reading in bed must have been relaxing to your eyes or you would have taken them off. And when you did take them off you clearly noticed the difference even though you could still read without them your glasses did make it easier on your eyes which is exactly what glasses are supposed to do. You said that you wore them to the office this morning and you were planning on wearing them all day. So I assume that means you do office type work which involves a good deal of close work. That is a perfect test for yourself. See how your eyes feel by the end of your work day. It makes sense that you don't feel comfortable wearing glasses since you have never wore glasses before and your eyes are still adjusting to your glasses. Also if after wearing them for a few days if they feel a bit too strong but you see an improvement you can always go on line and order a pair of glasses in maybe +.75 from Zenni. I agree with the others that you really don't need to wear glasses full time, That would be your option based on how you feel about wearing glasses and convenience of not having to be putting them on and taking them off and not having to try and remember where you last had your glasses. Let us know how your day of wearing them at work went.


Cactus Jack 03 Feb 2017, 09:44

Specs4Me & Sue,

It is not the Ciliary Muscles that cause Presbyopia, it is the gradual stiffening of the Protein that makes up your Crystalline Lenses over time. When you are young, you Crystalline Lenses typically have the consistency of freshly made gelatin dessert. You can focus incredibly close with almost no effort. This means that you frequently see young children lying on the floor, with a coloring book just a few cm or inches from their eyes, effortlessly coloring away. As you get older, your Crystalline Lenses get stiffer and harder and harder to focus. At some point, usually around 40, you need some external PLUS help focus close. The amount of extra PLUS you need to focus close is strictly governed by the laws of optics that relate focus distance and lens power. It does not matter if the extra PLUS comes from your Auto-Focus system, internally, or from external PLUS lenses, or from a combination of internal and external PLUS.

Unfortunately, wearing external PLUS reading glasses to help you focus close is a two edged sword. The help you focus close, but they also relieve the Ciliary Muscles of some of their work load. For their size (very tiny) the Ciliary Muscles are the strongest muscles in the body. Like all muscles they need exercise to maintain their strength. Wearing reading glasses reduces the amount of exercise they get and they begin to loose some of their strength. This makes your Presbyopia seem like it is increasing faster than it actually is and soon you need stronger reading glasses. Fortunately, you will probably never need more than +2.50 or +3.00 reading glasses or an Add, unless you need to focus closer than 40 or 33 cm (16 or 13 inches).

By the way, the age when Presbyopia becomes a problem depends on your genes, your vision correction, and your visual environment. It can become a problem at any age. These days, even teens are needing help reading the tiny text on their smart phones.

C.


Specs4Me 03 Feb 2017, 09:07

Sue,

The recommendation to wear new glasses full time applies mostly to those who have been diagnosed with latent hyperopia, which is not the case for you. You are in the throes of the onset of presbyopia which happens to all of us at some point in our lives. Actually, according to our most knowledgeable poster here (Cactus Jack) presbyopia begins at birth. Therefore, you simply need a little help, +1.25 should be fine, to take the pressure off of your aging eye muscles (remember that they begin aging at birth). The fact of the matter is that it is becoming more common for younger people to need reading help due in large part to the use of smartphones, tablets, gaming devices and the like.

So enjoy some relaxed reading with your new glasses, if you think they are a little strong, keep an eye out for some +1.0 readers. You will probably find as many do, that over time you will acquire numerous pairs of readers that you will leave all over your house so you can find a pair easily.


Sue 03 Feb 2017, 07:57

Thanks!

I am a bit confused. I went to buy +1.00's but the lowest they had was +1.25 so I bought those. I read posts here that suggested that when getting first glasses you should bite the bullet and wear them full time for 2 weeks, so thought I would try that but distance is just too blurry. So I can't wear them all the time..certainly not to drive.

I don't think I really need them, because I can really see close ok. But after reading for about an hour last night in bed, and taking them off the print in the book was much "dimmer" although I could still read the print without them.

I wore them in to my office this morning, and got a few comments..everyone noticed. They thought they looked good, but I am not comfortable with them. When I told a friend I was going to try to wear them all day, she said it's not a bad idea, but I will likely become dependent on them, as wearing glasses (she has since childhood) usually a one way street..once I start wearing them I'll become more dependent on them, and to keep good vision most exams will get slightly stronger till I need them full time. I don't think that I am ready for that yet.

So I guess my choice is to hold off for now, or try them for a while but take the chance that it will weaken my vision such that I will need them.


Soundmanpt 02 Feb 2017, 16:24

Sue

If you look at the "Hyperopia and Presbyopia" thread you may find some answers to your question or at least get an idea about your eyesight. The doctor that examined your eyes is correct that not too far down the road you can expect to be wearing glasses at least for reading and other close things. He is basing this on your answers to the various tests he did on your eyes and even your age. Nearly everyone as they approach that wonderful age of 40, or earlier, can begin to find small print on medicine bottle or even their phone more and more difficult to read or even if they are reading in dim light areas. I assume he didn't write you a prescription for glasses? You should go back, they usually won't give that out over the phone, and ask for a copy of your prescription. You may wonder why? Well once you have that information chances are if you only need a simple plus prescription such as +.75 or +1.00 or +1.25 or whatever. Anyway you can a cheap of over the counter readers at many stores such as Wal-Mart and drug stores for around $10.00. They are marked with the same +1.00 or whatever power you need. They start at +1.00 and go as high as +3.50. Now these glasses are cheap and the lenses aren't the best quality but they would at least give you a pretty good idea if you're ready for glasses or not. Or another option if you have pretty good insurance that will pay the biggest part of your glasses then you should do that and get better quality glasses with better lenses right away. Now you need to know even with the weakest glasses at first you can expect your distance vision to be blurry wearing them. But it is up to you weather you to decide if you want to wear them all the time or not. If you do decide to wear them full time you can expect that things at a distance will be slightly blurry at first but that will slowly go away and you would soon be able to see both distances as well as close up perfectly with your glasses. Or you may just want to wear them when you need them, like when your reading, using your phone or on your computer.So I would say having them is at least better than not having them. How do feel about wearing glasses? If you don't mind wearing glasses full time or part time then you should get them. By any chance did thye maybe give you your prescription? If so post it and we can give you an even better answer.


Sue 02 Feb 2017, 08:58

A store in the mall was offering free exams and I had time to kill so I went in. Last exam was probably 10 years ago. I have never needed glasses. For the distance part he flipped all kinds of lenses, some of which made the chart better and some worse...I had no idea how I did. Then he put up a stick and card with small print, on which I could read even the tiny letters, but when he clicked the lenses I could see the print better. When he finished he said my distance vision is really ok, but if I want I could get glasses for reading. He said I don't really need them yet, but likely will soon and that glasses will just make it easier for me to hold a book comfortably and will tire me less. He said it is up to me. So I am not sure if I should get them or not, or what they will do to my close vision. If found this site but not a similar situation. Should I get the glasses? If I do should I wear them full time? Part time? I am only 37.


Soundmanpt 01 Feb 2017, 15:23

Catwoman

I was wondering if you noticed any change in your vision during pregnancy or not. Yes what you read is correct but like you read it effects some but not others. I told this before but several year ago a friend I knew from one job she worked at changed jobs and I hadn't heard from her for a while. I did see her sister every so often and when I saw her sister she told me that her younger sister wanted to see me about glasses. I went to where she was working which was a Walgreens drug store. I was completely shocked when I saw her because she was extremely pregnant. She knew i was ordering glasses for people and had sample glasses in various prescriptions. She told me that her eyesight was so bad that she wasn't able to drive at night anymore and could barley drive during the day. Anyway she was hoping i might have glasses she could buy or borrow from me. I went and got several with different prescriptions and i had her start with the weakest ones first and left her go to each one until she found something that might help. She went through tham and finally when she came to the last pair I had she said they worked the best. They were -1.25. I just gave them to her and she was so happy to be able to see. She siad as soon as she had her baby and her eyes went back to normal, she always had perfect vision, she would return my glasses to me. I think I stunned her when i told her that her eyes were going to go back to her perfect vision anymore and that she would be needing glasses from then on. I saw her a few months after she had her baby and she was wearing new glasses. She asked me if I wanted the glasses back that I gave her and I told her no. She pointed to her glasses and said that I was right. She went and got her eyes examined about a month after she had her baby and she already knew that she couldn't see without glasses so she knew going in she would be getting her own glasses. She said that her glasses were -1.50 so only slightly stronger than the ones she was wearing. i asked her if she planned on getting contacts and she said once she got used to wearing glasses she really kind of liked wearing glasses. So if you had a change in the in between year it was likely due to being pregnant. That is if your eyes were already stable and then you needed an increase.


Catwoman 01 Feb 2017, 14:26

I read about how myopic women (such as I) can become more myopic during pregnancy. I do not recall having noticed any changes in my vision during my 2 pregnancies, but in my biennial eye exam between births, my prescription did become more negative as it were, by a half diopter or so. After that, my vision stabilized until the last 8 years when the "minus" has decreased.

Jacey,

Sorry to be slow getting back to you. You are doing the right thing. Few of us here are Eye Care Professionals (ECO). I am not and don't pretend to be. I am an Amateur in the original French sense of the word as someone who studies a subject out of love. My background is Electronic and Computer Engineering. My interest is vision and optics is related to my own vision problems and the inability to get satisfying answers from all but a very few ECPs.

Most very young children react unfavorably to anything on their face, but quickly discover that whatever those things are, they let me see better and become very upset when you have to take them off at bedtime.

We wish your daughter the very best. If we can help with answer more questions, please feel free to ask.

C.


Jacey 09 Jan 2017, 11:36

Her new prescription for her left eye is -10.25, and everything else is the same. She jas loved her glasses from the moment her dad put them on her. Both doctors basically said because she is so young, her myopia is most probably developmental issue. They both reccomended we keep a close eye on her vision, and get her eyes checked regularly because it is very likely her prescription will need frequent adjustments. This doctor was a bit concerned about the difference between both her eyes.


Cactus Jack 07 Jan 2017, 16:47

Jacey,

I am very curious what the doctors have said and your daughter's new prescription. How has she reacted to the glasses. Most very young children initially try to reject the glasses, because they are a strange thing on their face. Once they discover that there is an amazing world out there that they can see with their glasses and it disappears without them, they are very unhappy when you take them off.

If the glasses allow your daughter to visually explore the world around her, I would urge you to consider learning teaching her Baby Sign Language. It is amazing what that can do to speed mental development and learning to talk. At first I was skeptical about the latter, but it turns out that once the baby learns that she can communicate her wants and needs more quickly and efficiently with the sign language, it ends the inefficient crying. It doesn't take long before the baby can hold conversations with the mother using sign language for one side and voice for the other and then not much longer for both sides of the conversation to be spoken, when the speech centers develop.

Of course decent vision is necessary to clearly see your hands as you teach her the sign language.

May I as your daughter's name?

I am very happy that you have been able find out about your daughter's situation and have taken action to do something about it.

Please keep us posted about her progress.

C.


Jacey 06 Jan 2017, 16:53

We went in this morning, and the doctor basically confirmed everything the other doctor said. He did however come up with another prescription for her left eye. Her new glasses should be ready tomorrow.


Cactus Jack 05 Jan 2017, 14:20

Jacey,

Just some thoughts. Hopefully, you will get some answers tomorrow. Please let us know the results.

She was a full term baby, and her pregnancy was my best and easiest. I never got sick, however as usual my asthma came out of hiding and started acting up again. My mom came over from the UK and stayed with us for the end of the pregnancy until the baby was a month old. Also, my in-laws stayed with us for a couplr of weeks during the pregnancy, and they are from France.

Cactus Jack 05 Jan 2017, 01:56

Jacey,

Did you have any illnesses while you were carrying your daughter? Was she premature? Were there any problems during the pregnancy? Did any close family members travel overseas and return during the pregnancy?

Some diseases are notorious for causing eye development problems during gestation. For example, Rubella, also known as German or 3 Day Measles, is famous for causing eye development problem, but not usually Myopia. Often it disturbs the development of some of the lenses in the eye that results in extreme Hyperopia.

Eye development problems do not happen as much in the North America, but it its is more prevalent in South America. The father of one of our members sponsors an eye clinic in the area in eastern Brazil near the equator. They have discovered an unusual number of people who are very nearsighted. One a young boy of about 10 who has myopia in the -20 range and a young woman in here early 20s who needs -29 glasses. Unusual in a thin population. The two are biologically un-related. The cause is unknown.

There could be other Virus effects that we really don't know much about. A good example of a Virus causing fetal development problems is the Zika Virus that apparently started in Brazil, but has been brought to North America by mosquitos or returning travelers.

C.


Jacey 05 Jan 2017, 00:06

Thabks for the suggestion,I made her an appointment for Friday. To answer your question, no, I cannot think of anyone with myopia let alone high myopia in my husband's family, and in mine all I can think of is my nephew who is nearsighted but not much at all. I don't mind you asking me questions on here. Feel free to ask, and if something is too personal I will either respond via email or the website you mentioned.


Cactus Jack 04 Jan 2017, 22:23

Jacey,

It is highly likely that your daughter will become more myopic as she grows up. but it depends on the cause of the high myopia. I don't want to get too deep into optical physics here, but all refractive errors are fundamentally caused by a mismatch between the total power PLUS power of the eye's lens system and the length (size) of the eyeball.

There is no way for us to know exactly what is going on with your daughter's vision. It will be interesting to see what her reaction will be to the glasses. Initially, she may not like them and try to pull them off her face, but if she soon realizes that there is something more to see out there, that is a good sign.

The biggest danger with high myopia is that if the eyeball is growing too fast. That excess growth may put stress on the tissue that attaches the Retina to the back of the eyeball. That stress can cause Retinal detachment and loss of vision. Fortunately, there are ways to re-attach the Retina if caught in time.

I strongly urge you to make arrangement for her to be seen by a Pediatric Ophthalmologist as soon as possible to find out exactly what is going on.

At this point, if excess growth is causing the problem, we have no way to slow down that growth or speed it up, either. Eyeball growth seems to have a very strong genetic component. Do either you or your husband have any ancestors who were extremely myopic?

I don't know the actual numbers, but high myopia is not very common, but that is possibly because the high myopia is not discovered this early. We have had a few mothers who posted here asking about a 4 to 6 year old that has been discovered to need glasses in the -6 to -10 range. High Hyperopia seems to be more common because it is often caught by the eyes trying to turn inward or cross. Usually children with significant Myopia do not have the eyes turning inward problem. One of the problems in dealing with high refractive errors in children is hat they don't have any way to describe what they are seeing. An ophthalmologist who specializes in children's vision problems can do the best for your daughter.

I would like to ask a few more questions, but I think it would be best if you contacted me privately at cactusjack1928@hotmail.com or as a private message on the Vision and Spex site.

C.


GreginColo 04 Jan 2017, 17:34

I don't know what the process or procedure would have been to diagnose the need for such a high level of myopic correction in an infant, but hopefully the Optometrist also made a recommendation for some much more specialized and higher level of diagnosis and evaluation, as suggested by Cactus Jack, to help all involved better understand the situation, and what options, if any, may exist.


Jacey 04 Jan 2017, 11:01

We went to an optometrist. We live i America. I have a few questions. I have some questions, will my daughter's eyesight get worse as she grows up? Is she close to blind, or in danger of getting there? Is there anything out there that can fix her eyes. Not glassed which only provide a fix while you have them on, but a real permenant fix? Also, how uncommon or common is this?


Cactus Jack 03 Jan 2017, 21:46

Jacey,

Your 6 year old son is a little bit Hyperopic (far or long sighted), which is not unusual. Most babies are born with Hyyperopia and gradually grow out of it. The +1.25 glasses will make it easier to focus close. He was probably born with much more Hyperopia than he presently has and he has grown out of most of it.

You are right to be concerned about your 7 month old daughter. She is very Myopic (near or short sighted). That occasionally happens and there is likely nothing you could have done to cause or prevent it. From the practical vision side, she cannot see anything beyond about 10 cm or 4 inches, very clearly. It is good that the situation was discovered early. About 80% of the knowledge a child gains is through vision. The glasses will enable her to see more normally, but that may not be a full prescription. She may see the world as colored blobs without correction.

I have a few questions:

1. Was the eye exam appointment with an Optician, Optometrist or Ophthalmologist?

2. May I also ask where you live?

If the Eye Care Professional (ECP) you saw was not an Ophthalmologist, I urge you to make an appointment with a Pediatric Ophthalmologist or an Ophthalmologist who specializes in High Myopia.

C.


Jacey 03 Jan 2017, 15:19

Her prescription is -12.75 and -9.5 and she has -2.00 astigmatism in her right eye. My son that got glasses is 6 years old. His prescription is +1.25 in both eyes.


Cactus Jack 03 Jan 2017, 14:23

Jacey,

There are lots of reasons for a 7 month old to need vision correction, but without having the prescription, it is not possible to offer any explanation. A lot of visual development occurs in the first few months after birth and it is very important to take care of any problems ASAP.

Could you provide her complete prescription and if possible, your son's prescription and his age.

C.


Jacey 03 Jan 2017, 12:26

Just got the news that my baby girl and older son need glasses. I took the kids in for an appointment and the doctor said they both need glasses. They will be ready tomorrow. I just cannot imgaine my baby wearing glasses. She is 7 months old. How does a 7 month old wear glasses. More important how does a 7 month old's eyesight go bad? I don't give her any tablets, phones, ot laptops to play with. She only started watching TV last month, and that is only on Fridays for 1 hour. She eats healthy. I did not get glasses until I was 31, and my husband still foes not wear glasses.


Cactus Jack 14 Dec 2016, 15:17

dodgy eye,

When you go to the independent ECP, be sure and explain your visual history and the discomfort you have had during exams. Independent ECPs are of course professionals and they are also in business. Their long term livelihood depends on your satisfaction with their services, your repeat business, and possible referrals of other patients. An exam may cost may cost a little more than a chain, but it has been my experience that it is worth it.

If you have not seen one in a long time, you might consider an Ophthalmologist to make sure that your eyes are healthy and you are not showing signs of other health problems. The eyes are windows into the body and many "silent" killers are first discovered during an eye exam.

If there are any lurking eye problems, you are very fortunate to have one of the best eye hospitals in the world, Moorfields, in London. However, it is unlikely that you will need them at this time.

C.


dodgy eye 14 Dec 2016, 14:28

I go to a chain but thinking it may make better sense to go to an.independent who may have more time to spend, always feel incredibly rushed and with my eyesight issue I don't think they are able to spend the time needed. I work in HR mainly office based.


Cactus Jack 13 Dec 2016, 16:34

dodgy eye,

Yes. I suspect that the partial blockage of your Right eye kept the vision center in your brain from developing fully. It is important, when you are young, to get the full visual stimulus needed for that to happen. Fortunately, the tumor was removed soon enough for you to not develop full Amblyopia and complete loss of vision in that eye.

May I ask if you are using an independent Eye Care Professional (ECP) or a Optical Chain for your eye care? Also, your occupation?

C.


dodgy eye 13 Dec 2016, 16:11

I live in the UK, left eye sph -0.75 cyl -0.50 axis 10 and right eye sph -0.75 no cyl.

Its not a large prescription but with it, my Left eye corrects very well. With my right eye, the lens just seems to sharpen things up a touch but it still.doesnt see as well as left does.

What I described, does it make sense that my right eye woukd cause this difficulty and uncomfortable feeling during the eye test?


Cactus Jack 13 Dec 2016, 15:58

dodgy eye,

Absolutely! You and your examiner need to work as a team to get the best results.

There are two phases to an eye exam.

The first phase is the Objective phase. That is where the examiner either looks in your eyes with a Rentinoscope or an Auto-refractor while changing some lenses. This phase gives an approximation of your refractive needs.

The second and most important phase is the Subjective phase where you tell the examiner what you see. Remember, the examiner has no way to tell what you are actually seeing, only what you describe.

Also remember that Vision actually occurs in the brain. Your eyes are merely biological cameras. You brain has the ability to do some amazing image processing and can actually correct what you see, IF it knows what something is supposed to look like. The problems with doing the image correction takes quite a bit of effort and energy. It is much more efficient to correct the delivered images optically so little processing is required.

May I suggest reviewing the piece I wrote "How to Study for an Eye Exam" before your next exam. I have posted it several times here and on the Vision and Specs web site. Let me know if you can't find it or if you have more questions.

Don't be afraid to talk to the examiner before the exam starts. Most ECPs want to provide the most accurate prescription possible and are happy to have your active participation. If they seem reluctant to cooperate, find another ECP.

I am particularly in favor of "fine tuning" the Axis angle at the appropriate place in the exam and comparing the two images for sharpness when you are first shown both eyes working together, during the check for muscle problems. Those are both covered in "How to Study . . "

May I ask a few questions?

1. Where do you live? (country)

2. What is your complete prescription.

I have a question about why I find the refraction bit of an eye exam with one of my eyes incredibly hard.

A bit of background: I had a tumour above my right eye and it didn't get removed until I was 4. The tumour pretty much covered my right eye so I could only see out of it a small amount. There is no physical damage to the eye but for most of my life I have never seen as well out of this eye as the other and always feel it's my worst eye, I feel as though I do more ďseeingĒ out of my left eye. I am also left eye dominant(,I found this out during am archery lesson), it's fine detail that i find hard to discern no matter how hard I squint to see clearly. I have had optometrist in the past tell me that I have an amblyopia right eye. I am 30years of age now and have had a very light short sighted prescription in both eyes for many years- in fact a slightly larger prescription in my left eye than right but it corrects further down to 20/15 whereas my right eye corrects to just about 20/20.

I hope I can explain myself clearly, When I have an eye test where they keep both eyes open and viewing the chart instead of testing and blocking off one eye at a time, and they put a lens in front of the eye that's not being tested( makes the chart look blurred and fuzzy) and they start testing the right eye, I really struggle and feel that the blur from.the left lens is somehow encroaching onto my right eye and making it even harder for me to see/concentrate on the lens changes when they ask which one is clearer and feel like I have to shut my left eye to ignore the blur and help me concentrate on the lenses being presented to my right eye. When they test the left eye, I don't seem to have that problem. Ive also had eye tests where they test one eye at a time and block off the other eye and find that much easier to cope with especially for my right eye. Is the difficulty that I am having with my right eye because of the amblyopia/lazy eye and my other eye being quite dominant? Am I able to mention to the optometrist next time I find that method difficult and uncomfortable and ask them to block off the left eye when testing the right eye in future

That may explain why I haven't heard that term used for some time.

I believe that today, it is NOT wise to wait until cataracts "ripen", unless you are one of those rare people who need to have complete Crystalline Lens AND Capsule removal.

Before the development of IOL type surgery, cataract surgery was extremely serious as described. I have often thought that there was a hope that the patient would die before cataract surgery was actually necessary. Of course it might have been easier to remove the Capsule if the Crystalline Lens had become hard.

Today,, with IOLs, the Capsule is NOT removed. Instead, the Crystalline Lens is emulsified using a very tiny ultrasonic "jack hammer" through a very small incision on the side of the Cornea. A friend of mine, following the old ideas, waited too long. The surgeon was finally able to emulsify his Crystalline Lens, but it was not easy. That made the surgery take longer and be more risky than if he done it sooner. My cataract surgery done in 2001, took about 10 minutes. It was the closest thing to a non-event I have ever experienced.

At the surgeon's recommendations for Engineers, I opted for Mono Vision with single focus IOLs because of their better Visual Acuity. For the best vision, I wear Trifocals, but I can function quite well for most "less than precision" work, without my glasses. With Mono Vision, you use one eye for distance and the other for moderately close work. For extensive reading, because I have some Astigmatism, I have a pair of single vision reading glasses.

I was quite nervous about the first surgery. As I mentioned, it was a non-event. When I went back the next day for a check up, one of my questions was, "How soon can we do the other eye". Answer, "Two Weeks". Because I knew what to expect, it was even more of a non-event. I have never regretted it for an instant.

First of all you can't even think about cataract surgery until they "ripen" in other words until they are ready to be removed. So that really depends on how fast your cataracts are developing. But your optometrists needs to refer you to an ophthalmologist that will do the surgery. Now for what its worth you don't know how lucky you are to be living now as opposed to say 50 years ago. I remember my grandmother getting her cataracts removed and it was so much different back then. She was in the hospital for 4 days and she had lay will sandbags on each side of her head so she wouldn't move her head. And when she did go home she couldn't do anything fro weeks. Then she had to get her eyes examined and she came away with really thick plus glasses that made he eyes look like saucers. Then in the late 80's my mother had to get her cataracts removed and it was so much different. She didn't have to stay even a day in the hospital and the operation only took a couple minutes. I don't know what my mother's glasses prescription was but I know she wore glasses from when I was very young. And her glasses were bifocals as well. She had the ICL's and she came away with perfect eyesight and didn't need glasses at all. But like you she had worn glasses for so long that she wanted to continue to wear glasses. She talked the doctor into prescribing her glasses which did have some type of prescription that she wore until she died. The only issue she ever had was that she had become very light sensitive and besides having the changeable lenses, these were lenes that was before transitions, and she even had a pair of what thye call solar sunglasses that cover the eyes from all angles that she would wear over her glasses. Without a doubt i'm sure they have made numerous improvements since then as well. As far as how strong your current glases are and how much they can correct is not something I can answer. B ut I can tell you that about 8 years ago I was talking to an optician friend and she told me that her eyes were too bad for lasik. She was -14.00 and she got ICLs and her one eye was was slightly better than perfect 20/15 and the other eye needed -.50 correction and of course she was thrilled with the results. So it's very possible that they can correct your eyes to a perfect 20/20. And if you still want to wear glasses I have feeling the doctor will understand and fit you with some type of prescription for glasses.

Hi,

I know I have to have surgery at some point, itís not a pleasant thing but Iím not terrified of it. Iíve had surgical procedures twice before on my eyes for retinal problems. I just want to choose the right option as itís something Iím going to have to live with for the rest of my life. I want good distance vision and I love reading so itís important to me to be able to see very close up. Iím happy to wear reading glasses if thatís what it takes but I was led to understand that multifocal lenses can correct for near vision and far. My vision isnít perfect with glasses, especially in low light so I donít drive at night which is a limitation I would like to address. After surgery I would hope this could change.

My prescription is in excess of -20 in both eyes with some astigmatism on top of that plus an additional +3 for reading. I am very compromised without my glasses, there is very little I can do while not wearing them. When I wake up I canít see my alarm clock, even though it has digits 2 inches high and is right at the edge of my beside table as near to the bed as possible. I canít see my glasses at all and have to feel for them in the position I know I left them but even so when my hands touch them I usually blindly grab at the lenses and get finger prints all over them. Just this morning I went to retrieve my glasses and knocked a glass of water over that I had forgotten about and just didnít see. These are minor annoyances but as a 61 year old woman living alone I do feel vulnerable with such limited vision. I have a friend with a prescription of -6 and she can do lots of things without her glasses. She can walk around her house, go to the bathroom in the night, make a cup of tea, she even often reads with the book held closer than normal. Iíd be very happy with this level of vision.
