HI i recently had a red dot test for double vision. (You put some special glasses on, they turn the lights off and shine a light into the glasses, you should see a red dot in the middle of the white line)
Initially the red dot was to the left of the white line in my vision.
The doctor put a different lens on the glasses and the red dot was to the right of the white line.
My question is, does changing the lenses help measure how far my eyes are out of sync with each other?
For example, does he have a range of lenses each with a number that says how much its altering what you see?
