Answer 1

First, your question isn't very clear....and you didn't put the + or - signs in front of those numbers either.

The visual acuity doesn't tell the Dr. what prescription you need, just like seeing the prescription doesn't say what your visual acuity is.

It is safe to assume that your visual acuity would be much worse than 20/200 WITHOUT glasses on. That 1.50 astigmatism correction can affect the visual acuity by a great amount.

But what your acuity is WITH glasses on , only the Dr. while doing the exam would know for sure.

Unless you have an eye disease, or cataracts starting, you are probably close to 20/20 with them on , but some unknown factors may not make that possible.

If you are needing exact numbers for some reason, then the Dr. who did your exam will have that in his charts and can tell you.
