so i had to get a physical done and when it was time to get the eye part done i thought i was going to rock it... my eyes have 20/20...well as it turned out my right eye is now 20/30... but both eyes i now have 20/15. so i was talking to my girlfriend and she thinks that maybe i was straining my eye so much that i am losing vision? is that possible? anyone know anything like this? please let me know cause i dont want to wear glasses! thanks!
