Get your eyes checked at least once a year if you wear glasses or contact lenses, or if you’re over the age of 40. Keeping your glasses and contact lenses up-to-date helps keep your eyes from straining more than they have to. And an eye doctor may be able to spot early signs of eye disease. The best way to stop eye damage is to catch it early.

Even if you have perfect vision, it’s a good idea to have an eye exam every 2 to 3 years.
