He prescribed prism lens as a means of correcting this condition. My son wore them briefly but grew resistant since he didn't notice any difference when he wore them and thought they slightly obscured his vision. This optometrist predicted that our son's school work and athletic performance would be effected if he didn't correct this problem. Recently we've seen a drop off in both and are now wondering if we should revisit the correction of his vision. Can anyone comment on the affectiveness of prism glasses? Could one's vision really be a factor in a drop off in performance even if they have 20/15 vision? Thank you for sharing your thoughts and experience.

I just had my eyes checked two days ago, the Rx is a lot different than the one from two years ago. The one from two years ago says: OD +25 cylinder -.75 x 002 OS +50 cylinder 1.00 x 177 The new Rx from two days ago says: OD -25 cylinder -1.00 x 007 OS Plano cylinder 1.25 x 011 I don't understand the change. I understand Plano means no power, but my left eye has always been weaker than the right eye for few years. Can someone explain how I could go from having a power +75 in my left eye to plano in two years. Could anyone explain that. I don't have glasses w/the new Rx yet. I do have trouble seeing near and far without glasses especially driving. It's hard to read street signs w/o glasses. When I had the eye exam, and I had to look at an eye chart with my left eye with my right eye covered, I had trouble focusing on the letters. Shouldn't the sphere have a higher power than two years ago? Can anyone answer my question for me? I would appreciate if someone can help me. Thank you Laura I have a question about my Rx.

The person said something about there being a difference between the way that Optometrists (they might have said opticians) and Ophthamologists record the same thing. I indicated that this sounded odd to me. When I got home I checked the last several years and all of them have a significant difference like the one shown above....... but I can't figure it out. I would think that all prescriptions are the same so that any lab, doctor or vision center would know what the other was talking about. Can you shed any light on this? I just took my Mom to the Ophthamologist and she got a prescription as follows:

R Sph: – 4.50 Cyl: + 3.00 Axis: 180 Add: + 3.00
L + 1.75 + 2.50 165 + 3.00

When we got to where she wanted to get her glasses, WalMart Optical, the paperwork had translated the numbers to:

I would like to get a pair of swim goggles with a drugstore quality prescription, but my eye exam is over a year old, and I forgot to write it down, so my optometrist cannot tell me my prescription. Is there a way to try on reading glasses at a store and translate the number form "+" to "-"? My glasses are still fine, and I cannot afford an exam right now, but I would like to see better when I am in the pool. Thanks for your help. I have a question.

I've worn glasses for about 15 years (I'm 37) and I've never had this problem before. I was wondering if later displacement is normal? The Optometrist mentioned that displacements greater than 5 diopter can be a sign of an underlying neurological problem but because mine was 3.5 I should be fine. So, I was wondering if lateral displacements are rare and if I should consider having additional testing such as a neurological exam.

First, my Rx from 7/07 is OD: +1.00 -1.75 x 010 ADD +1.50 OS: plano -0.50 x 170 ADD +1.50 Yesterday, I 8/14/08, I got my eyes checked at a different optometrist's office. The Rx is OD: +0.75 -1.50 x 010 ADD +1.75 OS: +0.25 - 1.00 x 175 ADD +1.75 I'm concerned that the optometrist got the AXIS wrong on my left eye. Shouldn't the AXIS still be 170? Why would/could the AXIS change? Should I be concerned about the jump of the ADD POWER after only 1 year? In the new Rx, my right eye has less correction since last year's Rx. Does that seem odd or peculiar to you? I got my eyes rechecked after only 1 year because I'm thinking about either getting bifocals or Varilux progressives and wanted to make sure any new glasses I get would last as long as possible, considering how costly they are. I currently have a pair of polarized progressive sunglasses and a regular pair of progressives, noting that I bought both of those from Lenscrafters at the same time. However, while the progressive sunglasses have been fine, the regular progressive pair has not been all right. Is it possible that my eyes can't adjust to regular progressive lenses or is it more particularly the maker of the Lenscrafters Scotchguard Complete progressive lenses that my eyes can't handle? Thank you very much, looking forward to your reply. I have a few questions, if that’s all right.

First, my Rx from 7/07 is
OD: +1.00 -1.75 x 010 ADD +1.50
OS: plano -0.50 x 170 ADD +1.50

Yesterday, I 8/14/08, I got my eyes checked at a different optometrist’s office. The Rx is
OD: +0.75 -1.50 x 010 ADD +1.75
OS: +0.25 – 1.00 x 175 ADD +1.75

I’m concerned that the optometrist got the AXIS wrong on my left eye. Shouldn’t the AXIS still be 170? Why would/could the AXIS change?

Isn’t there normally one value per eye (when people tell me their prescription it is usually just one value)? My prescription is: OD: +25 OS: +050/025/75 Add +100 Is this a pretty mild prescription? Any help would be greatly appreciated! Thanks! Nette I just got a prescription for progressive lenses and don’t really understand my prescription.

Is this a pretty mild prescription?
