Wearing sunblock, a protective hat, and a shirt while outside has become common place for many looking to reduce their exposure to the sun. People also need to remember to protect their eyes by wearing sunglasses, reports the Mayo Clinic Women's HealthSource.

People who don't wear protective sunglasses may be putting themselves at increased risk of getting a cataract or other eye damage. The U.S. Environmental Protection Agency says that billions of dollars annually are spent on medical care to treat eye conditions, such as cataracts.

"It's best to wear sunglasses any time you're outside and need sun protection," says Dr. Amir Khan of May Clinic Women's HealthSource.

To help lessen the effects of the sun, people should wear sunglasses that offer 99 to 100 percent UV protection.

The Mayo Clinic Women's HealthSource also reminds people looking to purchase sunglasses not to confuse price with protection level. Pairs of glasses are usually more expensive because of their style, not because of the protection they provide, they say.

People who take proper preventive measures to stay in good health will find that they end up paying less on health insurance and related care fees.
