OKAY! So I have wondered this question for quite sometime and I cannot find the answer anywhere! No one may know the answer, but if you do PLEASE tell me. What exactly is the vision acuity that determines whether you get BCG's or not? For example is it only if you have 20/20 that you do not get glasses? I have 20/25 and I am far sighted. I don't care either way, it is just a question that has been on my mind.
