Answer 1

Eye glasses correct the incorrect refraction of your own eye lens refraction.

So imagine looking through a magnifying glass and you move it back and forth to get the best view. This is what your optometrist does when getting your baseline vision then asking you 1 2 or 3 a bunch of times. They are testing different angles of lenes to hone in your corrected vision with contacts or glasses.
