How do I deal with dry eyes?
user
When you have dry eyes, they’re probably irritated by the natural substances in tears.  It’s hard to avoid these irritants, since tears are constantly being made in our eyes.  One way to help is to apply a tear substitute.  Artificial tears provide the same substance your natural tears would make, but without the natural irritants.

It’s important to keep your eyes moist, so that they don’t get dry again.  In general, people who are sensitive to tear substitutes can get relief by using them two to four times a day.
