Eye doctor- Big difference between contacts and glasses perscription?!
Question: I went to the eye doctor today and I definately felt like my vision had gotten worse. Well I was right. When my doctor refracted ( i think that is the word he used) my vision went from being -1.25 in my right and -1.00 in my left both with -.5 astigmatism to -1.75 in both eyes without astigmatism. At least that is what he told me and what the glasses perscription said. When I went over to the contacts people, I already wore contacts I have for about 4 years, they had me put my old ones on and said since I could still read the 20/20 line with those they didn't need to give me a stronger perscription. I could read it but it probably could have been clearer. I know what I saw when I was with the doctor was clearer than that. So my question is why would they do this I mean .5 and .75 is enough to make a big difference right? Should I go back and have them fix it or am I just worrying over nothing? Thanks so much for your help!

With your old prescription of - 1.25 with a -.050 cylinder ( astigmatism correction)...that means your contact lens should be - 1.50 on the right, and a -1.25 on the left eye.
With no more cylinder now, your contacts should be -1.75 in both...according to the numbers you have given. You don't say what power your contacts are.
A 0.25 or 0.50 is quite a noticable difference in the lower power range like you have.
So, if your old contacts are .25 or .50 weaker than the 1.75 you need now...they really should be changed.
