First I need to do a vision test (don’t know if this is the term in English) in two days and I have to be able to see 20% from one eye, 40% from the other and 40% from both. I think this is not too hard given my prescription is not high: -0.75 sph; 1.5 cyl in both.
Before the test, should I use my normalized (with the exact prescription), my differentials (without the sphere), or nothing at all? Which of the possibilities is the best to prepare the eyes for the test?
When I look through the upper part of my eye, so, looking just under the eyebrows, and with the face facing down (hard to explain…), I see almost 20/20. Do you know why this is? And can it have anything to do with active focus?
Thank you very much,
