Why do my eyes sensitive to light? And why can't focus well?

[Ancho]

When I look up to light, my eyes get blur and wired,and the pain even get to my head. My pupil even get bigger these days. Why do this occur? Is it because that I watched 3D TV several days ago?

I suppose it has nothing to do with the 3D TV and I watch 3D TV always but never occur your problem. Maybe something wrong is happening in your eyes, I suggest that you see an opthamologist or at least an optician ASAP.

I don't know why you pupil get bigger but I may know why your eyes get sensitive to light. Maybe, your pupli is not dialating and constricting properly. The light is entering your pupil at to high of an intensity. This could be a reaction to medications, allergies, or nerve damage. Drugs can also cause this to occur. This will cause a delay in the pupils reaction time. I suggest you wear a pair of sunglasses to limit the light entering your eyes and maybe the sensitivity will go away. If it doesn't, i would recommend you to see a optometrist.
