Question: I just recently had a vision exam and i'm curious?

Since the board with the letters are far away, does it accurately evaluate the level of severity especcially when some people are near sighted and others are far sighted? As in a person who can only see far might get a perfect 'score'? Could anyone explain this to me? Thanks XD

That was just one part of the exam, right? You should also have been given a card with paragraphs in different size type, and been asked to read that up close. Plus there should have been additional tests with colors and shading and flipped letters. It's the combination of all those that make the tests accurate. Your are correct that one could get a perfect score on reading letters on the wall, but not be able to read the card up close. Or vice versa. That's why a good exam takes awhile and involves several different tests.
