Glasses
So I went to the doctor a few weeks ago during a check up could not see well out of my left eye. At the time I thought it was allergies as my eyes were running. During the first week of school I have been having trouble reading boards and getting a head ache from reading my books. So figured it could be my eyes. Turns out my right eye sees perfectly even better than 20/20, I think it was 20/10, but my left eye sees worse than 20/50. Which means my brain has been getting 2 different immages and using my right eye for most of my vision. Its interesting I now have glasses and realized the work is now in 3d again. I think they are a little off as there is small bluriness left. But very noticable difference.
