If you still happen to smoke cigarettes, now would be the time to stop. While smoking obviously damages your lungs, it damages your eyes, too. Anyone who smokes long term is at higher risk of eye damage. Quitting cuts down your risk for cataracts and other eye conditions.

Keeping a contact lens in your eye while the eye is irritated can turn this seemingly small problem into something much larger, such as corneal ulcer.
