Have you been to a neuro-ophthalmologist or a neuri-optometrist? That is the only way to know that your eyes are really okay. I had my eyes checked directly after my accident, and nothing was wrong with my actual eyes. It's the connection between your eyes and your brain that could be the problem. There are several possible treatments, including vision therapy.

I have to wear sunglasses all the time. I can only be on the computer for short amount of time, though it's getting better. I also use eyedrops, and that does help me. I had nine different things wrong with my vision per the neuro optometrist. Other people can speak to other possible reason for your symptoms, but it really could be your eyes.
