Eye wear prescription

[gaps87]

Hi, peeps i just went to the eye doctor and got a new prescription for my eyes. However it seems to me like they messed up somewhere. I asked about it and they gave me a response which i didn't understand.

Last year it was

OD: SPH -2.00, CYL -0.50, AXIS 040

OS: SPH -2.50

Now supposedly it is:

OD: SPH -2.50, CYL DS

OS: SPH -2.50, CYL -.25 , AXIS 100


See that last year it show i had astigmatism in my right eye and now it say i don't, but i do on my left eye.

Anyone else see a problem here?

-.25 diopters do make a difference to very certain people. Most of us cannot tell the difference; however, a truck driver that drives only at night can certainly notice the - .25.  Some people get really angry for having to change a lens out for a .25; however, they don't drive truck at night.

The question is:  How do you see with correction?  If you see perfectly well forget about it; if not, go back for a re-exam.  Not all optometrists are equal.  I found one that could not find a -3.50 astigmatism. He said: Oh, I saw a shadow but didn't follow it through. Four pair of glasses later, he finally got it..

Read my post again. There is virtually no difference in the prescriptions. You may not be abe to tell the old glasses from the new. Astigmatism especially of low degress can come and go as the eye changes.

Why pay money to a doctor you don't trust. See someone else next time, ideally an ophthalmologist (Eye MD). From what I can tell you weren't given a diagnosis.

My main concern is that the old prescription said i had astigmatism in my right eye and none in my left.

However the new one says i have in my left, and not in my right eye.

Should i be worried about this?

The doctor gave me a very, very quick check and im terrified at the thought of a bad diagnosis.

Thanks a lot for the help.

There is precious little difference in those prescriptions. The amount of astigmatism in both the new and old prescription is miniscule. The minimum amount of astigmatism is .25 diopter. Each "click" on the phoropter that you look through changes the amount of farsighteness, myopia or astigmatism by .25 diopter. Many people cannot tell differences that small apart.

If that's what you picked the chances are you'll see better with the new prescription. If you compare the new and old RX you likely won't be able to tell a huge difference.
