See your eye doctor. It sounds like the pressure in your eyes may be high, and could possibly be glaucoma. I'm not a doctor though, I just have glaucoma and I know the symptoms you are talking about. But definitley see your doctor.

The term "bifocal" refers to eyeglasses with two distinct optical powers, typically used to correct both nearsightedness and farsightedness in a single lens.
