Sorry, the last post was to liza.

Mild double vision is pretty common. The general medical term for double vision is Strabismus. At that means is that your eyes do not point in the same direction. There are four compound names for the Horizontal displacement depending on the direction and possibility of fusion : Eso and Exo are the first parts of the names. Eso means that the eyes try to converge or turn inward. Exo means that the eyes try to diverge or turn outward. If you can fuse the images, phoria is tacked on to the first part. If you can't, tropia is tacked on. For example: Esophoria means that your eyes try to turn inward, but you can fuse the images. If your Eye Position Control System (EPCS) can fuse the images pretty easily, most ECPs are reluctant to consider prescribing prism. If it is difficult or impossible for your EPCS to fuse the two images or you can keep the images fused only for as long as you concentrate, Prism in your glasses, Vision Therapy, or Muscle Surgery may be the only solutions.

A while back,I came up with what I call a Simple Prism Test that is based on Sir Isaac Newton's definition of a Prism Diopter. It is on the Vision and Spec web site, but it is hard to find. Would you be interested in measuring the amount of your double vision? I will post it here if you want to try it.

I have a few more questions:

1. What is your occupation?

2. Do you do a lot of close work

3. Can you tell if your eye are trying to turn inward or turn outward?

Cactus Jack

it's horizontal.


It was an annual exam. And i'll order new glasses, mostly because i want new frame.

Soundmanpt 21 Sep 2017, 09:16


I am curious, did you go for an eye exam because you noticed a change in your vision or was it just an annual exam? I ask that because the from your previous prescription to your current one is so slight. I think most people wouldn't even bother getting their glasses changed with so little change. A -.25 is the lowest possible change you can have. But like Cactus Jack said astigmatisms do effect your vision at all distances. Did you get new glasses? Even with such a small amount of CYL it still can take a little getting adjusted to.

Cactus Jack 21 Sep 2017, 09:03


There little if any relationship between a small amount of astigmatism and double vision. Larger amounts of astigmatism can cause what appears to be a small amount of double vision, but it does not go away.

When you see two images, can you tell the direction of the displacement? For example: Horizontal, Vertical, or a combination of both (Oblique).


liza 21 Sep 2017, 05:31

Cactus Jack thank you for answering. Is it possible that -0,25 cyl is reason for double vision? Because i notice that i got double vision on daily basis (for a few seconds), but i could stop it consciously.

Cactus Jack 20 Sep 2017, 19:20


You might see if you can find an eyeglass repair shop. Their primary business is repairing frames that have been broken. They might be able to drill out the fastener and install an optical screw of some type.


aviator-oo- 20 Sep 2017, 17:03

I have a question which doesn't quite fit with any of the themes, but I hope someone will be able to offer advice. When it comes to fitting RX lenses to frames which you buy as sunglasses, the general rule is that plastic frames must be made from the type of plastic which expands slightly under heat. Metal frames must have a screw on the edge of the frame to release the lens. I have a number of metal frames which I would love to have RX lenses fitted to, but the screw position is welded-up and there is no way of releasing the lens. Recently, I have received some metal framed glasses from where the RX lenses are fitted in a welded frame without a screw release. So, is there a way of getting RX lenses into metal frames without a screw? I know it is possible to Ďpop' non-RX lenses out of (and sometimes into) welded metal frames, but RX lenses? Does anyone know how this is done?

Cactus Jack 19 Sep 2017, 09:34


Yes, it frequently happens. -0.25 of Cylinder is very small and nothing to get excited about. Astigmatism affects vision at ALL distances and is particularly noticeable when reading small text.

Astigmatism is typically caused by uneven curvature of the front surface of the Cornea. Astigmatism typically changes very slowly, but unfortunately, it can appear to change significantly from one exam to another.

Often, the appearance of a significant change in the Axis of the Cylinder correction, while alarming, is caused by the lack of experience and understanding of the nature of that part of an eye exam.

The most subjective part of an eye exam is that of determining the Axis of the Cylinder correction. The way that is done is by using a supplemental Cylinder lens mounted with a pivot at 45 degrees. The lens is flipped back and forth on each side of the selected Axis and you are asked to judge relative blurriness of the letters you see. It is very difficult to do even if you have had many eye exams.

A while back, I wrote a piece "How to Study for an Eye Exam". In it, I described a method I use to improve the accuracy of the prescribed Axis. You may be able to find it online either here or on the Vision and Spex site. I am currently revising it and hope to post it again in the next few days.


Tom 19 Sep 2017, 06:47

Liza, my partner had the same "surprise" at her last exam, when her spheric correction did not change but she got a small cylinder prescribed for both eyes.

However, after getting her new glasses, for which I accompanied her on a Saturday morning, she exclaimed when still at the optician how the new cylinder/astigmatism correction made a huge positive difference for her. She is only -1.5 spheric, but now she wears her glasses more often than before, especially in the evenings, even at home and not only for driving.

Hope you enjoy the same beneficial change!

liza 19 Sep 2017, 02:57

i got new rx and includes low astigmatism, even if i never had it before. is it normal? im 32 yo .

The previous rx was:

R: -4

L: - 4

New rx is:

R: -4, -0.25, 170

L: -4.25

I was just thinking about what prescriptions people consider strong. When I first got glasses I was Plano in my right eye and +1.25 in my left eye. I considered it a mild prescription. My mom considered it very mild. In my head anything below 1.00 was very mild, but anything above 1.00 was just mild. I couldn't understand why my eye doctor made such a big deal of it. When my prescription increased to +1.75 in my left eye I still didn't think it was a big deal. Eventually I realized that prescription was too weak for me. I even tried wearing my +1.75 glasses on top of my +1.25 glasses. I enjoyed the vision it gave me. I conveniently didn't do the math and just considered it +2.00 or something. I didn't consider +2.00 strong. I was shocked when my next prescription was a bit over +3.00. I considered +3.00 a strong and thick prescription. When my next prescription was over +4.00 I didn't have the same shock. But my dad did. It seems like his cutoff was 4.00, while mine is 3.00.

Mr Jules 18 Aug 2017, 16:46

Presbyopia is advancing again. For several years, I thought my eyesight had stablised at +1.50 distance, with an addition of +1.75. But over the last 12 months, I've had two eyesight tests and as I could tell my reading vision was getting worse again.

Now my prescription is +2.00 for distance and an addition of +2.25. I didn't think my distance vision had got worse, too. It was only the last eyetest that I finally realised I was going to need new lenses. I've been wearing progressive lenses for some years.

Well, I've got my glasses reglazed with the new prescription. And what a difference the new lenses make. But I notice that I have to move my head more and learn to target my eyes through the centre of distance portion of lense to reduce peripheral distortion.

But the middle and close up vision is where there's most new benefit. But with these stronger lenses comes depedency. Without glasses, my distance vision hard to tolerate. And my close up vision is now horribly blurry!

I also have a separate pair of prescription single vision reading glasses at +4.25 which I prefer for extended periods of reading. It's taken about a week to get used to them.

I started wearing +1.00 reading glasses when I turned 40, for occasional use. I am completely fine with being dependent on glasses now. They are an intergral part of my appearance. They only thing I miss is not being able recognise someone in the distance, without my glasses. Worsening close-up vision is one thing, but worsening distance vision is harder to deal with (I think).

Soundmanpt 07 Jul 2017, 08:17


It would seem that if your eyesight doesn't seem to be quite as good as it was 8 months ago when you first started wearing -3.00 correction after having wore -3.50 that there has been some change in your eyes. I think since your still nursing it would be best if you can manage to hold off getting your eyes examined until you're finished with that. Having children for many women often does change your eyesight. I have mentioned in here about someone I know quite well that became pregnant. She had perfect eyesight, but with each passing month of her pregnancy her eyesight was getting worse. When she was about 7 months along she wasn't able to drive at night because she couldn't see well enough. I went to see her where she was working and I had several pairs of women's glasses in various prescriptions that I use for the vision group I work with. The strongest pair i had was only -1.50 I believe. All the weaker ones wasn't much help to her. But the -1.50 glasses seemed pretty close to what she needed. I gave them to her because i knew I could replace them. I didn't see her again until a few months after she had her baby. She was wearing a very nice looking pair of glasses that looked really good on her. Of course being a proud momma she wanted to show off her baby boy. She quickly offered to return the glasses I gave her and thanked me again for letting her borrow them. I told I didn't need them back. I complemented her on how nice her new glasses looked on her. She said she thought that once she had the baby her eyesight would return to normal which didn't happen. But she said she was okay with wearing glasses.

 06 Jul 2017, 19:01

I don't think your wearing your glasses full time made your vision worse. I mostly did not wear my glasses as a child and my eyes got worse. When I finally wore my glasses full time my vision still got worse for several years and then stopped getting worse. At that point I was -10 plus a lot of astigmatism. It seems that nearsightness (myopia) takes it's course whether we wear glasses or not.

NNVisitor 06 Jul 2017, 10:23


While I don't and never have worn soft contact lenses due to my astigmatism level I'm certainly familiar with the experinces of quite a number of soft contact lens wearers. Many wear them from morning to before going to bed every day. For years until in many cases they have a problem and then a trip to the eye care professional where they are told to stop wearing contact lenses for a few weeks, a few months or permanently.

Soft contact lenses can dry up during wear. That is not good for the eyes especially over a long period of time it can take it's toll.

While I wear gas permeable contact lenses I'm very careful not to overwear them day in day out. Each day typically morning and later evening I wear my glasses to give my eyes a break and to avoid eye problems from occurring. I've worn lenses over 30 years and by not overwearing them and allowing my eyes to rest I've avoided contact lense related eye problems and have not damaged my eyes.

SoCal 06 Jul 2017, 08:01

I'm pretty much -3.0 across the board, contacts included, with the exception of the very minor astigmatism. I'd say I've had this rx for about 8 months now and just starting to notice that it wasn't as good as when I got it, and even then it wasn't perfect. I had gone about 2 years previously without an exam and living off hoarded contact lenses, haha. Prior to the -3.0, I was a -3.5, again, not very much difference, but I did notice that there was one. Between the two different rx, I had two children and that really threw my vision all over the map. I am still nursing and partially weaning my youngest and I am wondering if that is changing things and making my eyes stabilize to my previous pre children rx. Like I said, this pretty negligible but I was curious. I have been wearing my glasses more recently for sure and I'm kind of liking it. My eyes feel like they can breathe. I am partial to the Moscot frames currently have and was looking into getting sunglasses to combat this California sun but decided against it. I decided to order a different brand of contacts that my dr prescribed (he gave me two options) to me and continue wearing my regular sunglasses.

Soundmanpt 06 Jul 2017, 07:16


So I assume when you say that you feel like you may have been under prescribed coming from -3.50 in both eyes to -3.00 both eyes you're referring to your contact lens prescription in both cases? That is very strange to happen. But if your eyesight has improved a bit it is going to take a little time for your eyes to adjust because they are used to the stronger prescription. So I would suggest giving it a try for maybe 2-3 weeks and if you still feel like you still need your lenses to be stronger go back and tell your optometrists that you would be happier with the stronger lenses. They are their to please you and shouldn't have any problem putting you back in -3.50's again if your more comfortable with them. Sounds like your eyes are starting to rebel against your contacts if you're having trouble wearing them for 14 hours or more like you used to do. But if you're really wanting to start wearing your glasses more often to the point where your about 50/50 between glasses and contact wear that should help a lot. Maybe try wearing glasses for your everyday life and only wear contacts for special occasions, working out, doing sports and maybe going out for the evening. You have shown several really nice looking pairs of glasses that you bought so you're glasses are trendy enough.

SoCal 04 Jul 2017, 23:37

Thanks everyone! I actually think I was slightly under prescribed having come from a -3.5 in both eyes but I'm okay with it for now. I'm actually enjoying the small amount of cyl correction in my glasses, It definitely is having me in my glasses more than contacts. I'm hoping for a 50/50 split between contacts and glasses because I can tell that I'm having a harder time wearing contacts for 14 hrs or more like I used to.

Soundmanpt 04 Jul 2017, 17:36


What your doctor did is very common for them to do and in nearly every case you're going to see better with your glassses having the full complete prescription tan you will with your contacts not having the CYL and adding slightly to your SPH in that eye. You of course have the option if you don't mind the added cost of going to a toric" lens for that eye and including your CYL. But I warn you that "toric" lenses are about 3 - 4 times more expensive than your normal lenses are. So unless it really bothers you I think you're better staying with what the doctor prescribed you.

NNVisitor 04 Jul 2017, 17:17

Cactus Jack, SoCal

Yes -3.25 is just slightly higher so it might do the trick. I think you can also get soft contact lenses for astigmatism so if you ordered contacts on line you can try ordering online at first just for the eye with astigmatism and use that lense with the -3 in the other eye and see how it works.

I've worn RGP lenses for my -10 myopia and astigmatism in the -2 range. My vision has been absolutely great and sharp in those contact lenses but not each time they were fitted. Those lenses have to sit on the eyes a certain way. If they rotate somewhat the astigmatism correction is off and thus vision is not so clear. Also those lenses work together with the tear flow under the lense for the optimum correction. In your case Socal with just a little astigmatism in one eye only you probably don't need the more complicated fittings that I had with multiple visits to get the fit right.

Cactus Jack 04 Jul 2017, 15:20


With a sphere correction around -3.00, Vertex Distance effects are negligible, so there should not be much of a difference in the sphere department. With only -0.50 of Cylinder, it is common to add 1/2 of the Cylinder to the sphere and avoid fitting topic contacts with all their associated costs and problems.

You might consider some -3.25 contacts and see if you like them better.


Cactus Jack 04 Jul 2017, 15:14


That is a pretty good increase. What was the interval between the -0.50 and the -1.25. Astigmatism usually changes slowly. Axis is often more critical than the actual Cylinder correction. Listing of the Cylinder without the Axis number is meaningless.

Have you read my post on "How to Study for an Eye Exam". There is a section in there about improving the accuracy of the Cylinder/Axis part of your prescription.


SoCal 04 Jul 2017, 15:05

My current rx is -3.0 and -2.75, -0.5. Could there be a difference in my vision from glasses to contacts. Dr gave me -3.0 contacts for both eyes saying it will cover the minor astigmatism. I feel like my glasses give me better vision but that could just be that glasses give me better vision in general.

Rob 29 Jun 2017, 05:52

I recently had an eye test and found that the cyls have suddenly increased in both eyes from -0.5 to -1.25, the sphere remains much as before at -1.25/1.50 I got new lens fitted but i'm finding them to feel rather strange and hard to get used to. The vision is very sharp though. They feel like they're pulling my eyes. Is this something that I will adapt to over time?



NNVisitor 23 Jun 2017, 22:44


I don't think your wearing your glasses full time made your vision worse. I mostly did not wear my glasses as a child and my eyes got worse. When I finally wore my glasses full time my vision still got worse for several years and then stopped getting worse. At that point I was -10 plus a lot of astigmatism. It seems that nearsightness (myopia) takes it's course whether we wear glasses or not.

One advantage we do have is close reading vision while others absolutely need reading glasses. This usually happens in our forties.

Jen 23 Jun 2017, 15:38

@julia yes it would be ok if are eyes stayed at -1 or -2 so we would only need glasses for distance and not need for reading. But the problem is when we get use to seeing clear with glasses on and then we relie on them all the time until we can't go without. Maybe if I just wore mine when I really needed to my eyes wouldn't of got so bad. I'm with -7.00 and been wearing glasses for 40 years is not a problem. Is better I'm not looking for reading glasses of trying to squint without to read something

Delilah 04 Jun 2017, 14:19


My boyfriend wears glasses and contacts and he has a very interesting prescription. He asked me to order him new glasses and this is his prescription. I have never seen a prescription like this. Will someone please explain to me what this all means.

OD: SPH +2.50 CYL-0.50 AXIS 150 ADD1.50

OS: SPH +4.00 CYL-1.25 AXIS 135 PRISM1 6 BASE1 BO ADD1.50


Julia 03 Jun 2017, 12:13

Is there any problem with being shortsighted? I've never had a problem with it and now I think it's great I don't need reading glasses and I'm 45. But have worn glasses full time for the last 30 years with a -6.00.

The optician says it's better if you have low shortsighted then would only need glasses for distance and none for reading?

SC 21 May 2017, 10:23

Just had a regular test. Age 52 and astigmatism doubles!


OD +1.5 0.5 x80

OS +1.75 0.5x173

Add 2.25


+1.75 1.00 x80

+2.00 1.50 x173

Add 2.25

Left eye really +4.50 but brain can't handle it so cosmetic lens

Soundmanpt 16 May 2017, 13:36


You never have stated what you age is and that is an important factor here. I can only assume that you might be in your early 40's based on what is going on with your eyesight. So based on that assumption you need to understand that your near vision isn't going to get better. It just doesn't work that way. Almost certainly it is going to worsen no matter what glasses you decide to get. Even though your nearsightedness seems to have improved, it really hasn't changed hardly at all because of the addition of astigmatisms you now have. Visually you are only about -.25 better now than you are with your current -1.25 glasses. I don't have to tell you that -.25 is practically nothing. So I doubt that trying to wear your glasses less is going to be any easier for you than it would now by taking your glasses off. For some reason you seem to think that wearing glasses is somehow going to make your eyesight worse. That is not the case. No matter which way you go you need to accept that your eyesight is going to continue to change and not for the better.

R 16 May 2017, 11:54

Basically can't read with glasses on so now need to take them off to read. Can read fine with glasses off unless very small print on a label. I am

Surprised how quickly near vision has got worse, feels like just a few weeks!

Worsening of near vision now more bothersome than blurred distance vision, that's why I am wondering should I just try to wear glasses less. And it's only in last year that I started wearing glasses much more during the day.

NNVisitor 16 May 2017, 09:59


Wearing your glasses shouldn't make reading more difficult if you pick one of the three options below.

Are you comfortable taking off your glasses to read? Or do you have to strain your eyes if you read a lot? If you're straining your eyes to read then reading glasses will work for reading if you don't mind switching glasses to read. Progressives and bifocals have a separate area with the add for reading. You would need to adjust to the fact that such glasses require looking through different parts of the lens for distance and another for reading.

R 15 May 2017, 21:04

It seems that the add might push me from wearing glasses a lot to fulltime if reading might be more difficult even though distance if anything is better?

Should I maybe try to reduce glasses use to stop dependence?

Or am at I a point were I have to accept that a combination of factors make full time glasses wear inevitable?

KL 15 May 2017, 14:42


If you were to get bifocals, the reading segment (or single vision glasses for reading) would be SPH +0.5 CYL -0.5 and SPH +0.25 CYL -0.5 (algebraically adding +1.25 to your distance prescription) which will be more comfortable than just removing your -0.75 -0.5 and -1 -0.5 glasses. Your astigmatism is pretty small, but they'll correct that, and you'll have some plus sphere that means less accommodation necessary for you.

Which also means that yes, if you wear bifocals (or single vision reading glasses, for that matter) it will make it harder to read without them because the ciliary muscles responsible for your ability to accommodate will get weaker when they donít need to work as hard as they have been.

Soundmanpt 15 May 2017, 14:09


Bifocals in your case shouldn't make it anymore difficult for you to read without glasses because all they are doing is eliminating the -1.25 distance. So what you would be really seeing is 0.00 through the add segment of your glasses. But you do need to understand that the reason this is happening to you now is because your eyes are beginning to change as for as needing reading help so it probably won't be long no matter what you do before you're going to need reading help.

It doesn't matter what most people would do if this were their first glasses. They aren't your eyes what matters is what you want. It's really very simple if you get single vision glasses then you will have to constantly be removing your glasses to see small print. If you get bifocals you won't need to take your glasses off to see small print.

R 15 May 2017, 13:35

If go with bifocals will it make it more difficult to read without glasses?

If this was first time glasses would most people go for bifocals or single vision?

Soundmanpt 15 May 2017, 09:10


Apparently if you have been wearing your -1.25 glasses nearly full time for a good long while without any vision problems close up, but now you are starting to experience difficulty with seeing close up it means your eyes crystalline lenses are starting to harden which is why your eyes aren't as able to ficus close up anymore. You didn't state your age but this generally starts to occur in your early 40's.

As far as what to do about getting glasses is really up to you. Since you seem to be pretty used to wearing your glasses almost full time anyway I think it would be much more handy to go ahead and get the full prescription so you don't have to be constantly removing your glasses to see things close up. By putting the +1.25 in your glasses what that is in effect doing is cancelling out your -1.25 distance prescription. So it would be the same for your eyes as having no prescription for the reading add. Also you are in fact slightly less nearsighted, however, you now have a bit of astigmatisms to deal with that you apparently don't have in your current glasses. So astigmatisms effects your eyesight at all distances. I hope to not confuse you but if you were sya only considering getting contact lenses with just your new distance prescription the contacts would be -1.00 / -1.25. The doctor would take half the value form your astigmatisms and include that in your distance correction. So really only a very slight decrease in your prescription. But having the actual astigmatism correction in your glasses would still provide you with slightly better vision than contacts would.

So after all that what you're left with is to decide if you want to only get single vision glasses for distance with your new prescription not including the +1.25 add and have to remove your glasses for seeing close or get get bifocals / progressives and not be needing to remove your glasses to see close up.

R 15 May 2017, 00:09

I have had a prescription of -1.25 and have been wearing glasses almost full time for a while. Recently up close is a bit blurred. New prescription is -0.75 -0.5, -1 -0.5 with +1.25 both eyes! Option was to get the prescription or just take off glasses for reading? Should I get glasses with the new +1.25?

As my distance need has apparently lessened, which I didn't notice do I need to continue full time glasses or should I try to wear less?

Soundmanpt 14 May 2017, 08:22

Maria Et

To fully answer your question about your boyfriend's eyesight is really a bit complicated. But you are correct in thinking that + glasses are commonly thought of as reading glasses and not needed for seeing distances. However + glasses are also often wore for farsightedness as well which is a bit different than just being reading glasses anymore. In your boyfriends case he also has a very high amount of astigmatisms which is the -3.25 and -4.25 numbers you see on his prescription. That alone would cause him to need his glasses for everything.

Maria Et 14 May 2017, 01:29

Can someone please explain my boyfriend's prescription to me?

left eye is +5.75-3.25x165

right eye is +5.50-4.25x170

His glasses magnify his eyes, I was always thought + was for reading but he wears his glasses or contacts for everything.

I want to understand his eyes more...

MKWL 10 May 2017, 22:09

Thank you guys!

I finally got my new glasses. They look thicker, but everything looks super clear with them. Also, the reading ones really help.

GreginColo 26 Apr 2017, 18:30

MKWL; it looks like you have already gotten a o]possible interpretation of your new Rx by someone more informed about such than myself. It does sound like a fairly complex Rx. However, you also asked about your + Rx, which could be part of the normal aging process, for most people beginning in their early to mid 40's, were they/we loosse some ability for close up focus, hence the need for reading glasses, which I think is basically what the weaker of your new Rx's is intended to accomplish. You didn't mention your age to help confirm that. Also has you distance Rx stabilized or has it continued to increase from your prior?. You ECP should be willing and able to answer your questions, but if not there are many helpful and well-intended people who contribute to this site. Best of luck adjusting to your new RX. Do you always wear glasses, or sometimes contacts?

 26 Apr 2017, 15:07

MKWL, I could be wrong but I think you have left something out, because what you have written doesn't make any sense. However I am guessing that what you left out might be the reading for the right eye distance. I have taken a wild guess and I think this might be your full prescription:

OD: -16.75 x -3.75 x 120 with 12 D base out prism distance

: -15.50 x -3.75 x 120 with 14 D base out prism mid range

OS: -14.50 x -3.25 x 135 with 12 D Base out prism distance

: -13.25 x -3.25 x 135 with 14 D base out prism mid range

with a +1.25D ADD.

If I am reasonably close, you do have a strong prescription. You require R-16.75D spherical and L-15.50D sph. with another R-3.75D at 120 degrees and L-3.25D at 135 degrees of cylinder for your distance correction. You also require 12 degrees of base out prism for each eye.

For your mid range vision your distance correction is reduced by -1.25D Your astigatism stays the same, however your prism is increased by 2 degrees base out.

The additional prism in your mid range vision is required to bring your eyes to focus up close. No further increase is needed for your reading so it is indicated by a +1.25D ADD.

If you did not require cylindrical or prism correction your prescription would likely have been written as:

OD - 16.75, OS - 14.50 with + 2.50 add multifocal

Maxim 26 Apr 2017, 14:17

I totally agree with Tom.

The correction needed is very low indeed, and you could give a try to the simple lenses without astigmatism.

Best wishes!

I'm not that expert but your astigmatism sounds low esp in the right eye, which can easily survive without cylinder.

I'm sure you'd be ok with -1.5 and -1 sphere, no astigmatism at all.

Let see what others think.

I had recent eye test, astigmatism went up. I'm debating trying contact lenses for occasional use but heard that toric contacts are not very comfortable and are more expensive. Is the optometrist likely to give me toric contacts with this prescription

Well, I had an interesting appointment today. The appointment was a little different today. At the end the doctor opened up both eyes and asked if I saw one or two images, and I saw two. He then did some weird stuff, like kept waving something in front of and away from my eyes, and back and forth between my eyes and held this ruler looking thing to my eye. This was then done by looking at a hand held card. Also, after that the doctor pulled out a smaller chart and had me try to read it with the black glasses thing, and I couldn't read it all. He switched some stuff up, and it became clear and easier to read. When I went to pick out glasses they told me I needed two, One for far, and one for reading. The girl also said something about a prism and presbyopia. I am so confused. When I looked at the paper with my prescription, there were two joined charts there, and one on the bottom of the page instead of the usual one. The the top part of the joined chart is distance and the bottom half is near. I don't know how to really understand a prescription, so was hoping some one can help me. All I know is I am very nearsighted, and the bigger the number the worse my prescription, and my numbers are pretty high. My prescription is: the distance part has the following numbers in the first row: . The second row in the distance part : -14.5, -3.25, 135, 12, and out. Now for the near part of the chart, the first row: -15.5,-3.75,120,14, and Out. The second row of the near part: -13.25,-3.25,135,14 and out. The other chart on the bottom of the page is longer, with more columns, but only has two rows. It reads mostly the same, but the extra columns, which I think just blends the other charts into one, but has this +1.25 in both rows under the ADD column. Why is there a + I thought I was nearsighted? What is the plus doing, and why isn't there a plus in the other merged chart?

Sorry for being so long, just really confused. Hope someone can help.
