Thank you everyone for your support.
I have an ophtamologist appointment at Stanford this Monday. My main symptom is chronic headaches and light sensitivity in my left eye and I also feel that my left eye doesn't focus properly in conjucntion with the right eye. I've had my eyes examined before and they did say that I still have 20/20 vision.

Can you guys give me some tips on questions to ask my Ophtamologist on these particular issues? Do you think wearing prisms in my glasses will help me? Thank you.
