Hi guys, I'm going to be joining up soon. But I have pretty weak eyes. I can only see third line up on the chart at the opticions. However, my vision cannot be corrected any better. They tried putting lenses in but I could not see any better. I'm ok for driving and can see most things pretty well, but i can't see the bottom 2 lines with either eye. Is this acceptable for the Marines? Thanks in advance. I've tried searching for info but can't find anything that says exactly what the standards are.
