You'll go blind if you watch TV in the dark.

You can go blind if you look into the eyes of your mother-in-law.

You'll go blind reading under the covers.

You'll go blind reading in a dark room.

Cross your eyes and they'll stick that way for life.

You get sties in your eyes from peeing in the road.

If someone presses on your neck, your eyeballs will pop out.

There must be 100 ways to put your eye out.
