Hey doctors , Thought I'd post my concerns here since I'm usually too nervous to ask my own Ophthalmologist--and they always sugarcoat their words anyway. I've always had poor eyesight--glaucoma runs in the family, in fact, and it's basically a matter of when I get it. My prescription for contacts is currently OS -6.5 and OD -7.00 ....I have bad astigmatism too. My eyes have always been weak, and though my prescription stayed virtually the same in high school, they have progressively gotten worse in college, due to many all-niters, straining my eyes when I'm viewing cells through the microscope, etc. Of course, I'm expecting further worsening in vision during med school. My question is, how bad can your eyes get before you really can't function effectively anymore? What about becoming a surgeon (what I've always wanted to be). I can't imagine an incredibly near-sighted person being a fast and precise surgeon. Sigh. I can still move around the house without my glasses/contacts, but outside, I'm totally lost. I don't want to spend the latter half of my life in a blurry world. What do you guys think? Are there any preventive eyecare methods that I should start practicing? Do you think limiting my time watching TV, computer, and reading would help? Thank you all for your input!!
