One in six Americans over age 65 has a visual impairment that cannot be corrected with glasses or contact lenses. This is often caused by common eye conditions and diseases. Among older Americans, visual impairment is one of the most significant contributors to loss of independence; it is also associated with a higher prevalence of chronic health conditions, falls, injuries, depression and social isolation.

The American Academy of Ophthalmology recommends that seniors follow these seven tips to help protect their vision:

1. Get an eye exam.

Adults age 65 and over should get a medical eye exam every one to two years. Regular eye exams are crucial in detecting changes in vision, which may be a symptom of a treatable eye disease or condition. Seniors who have not had an eye exam in the last three years and for whom cost is a concern may qualify for EyeCare America. This is a public service program of the Foundation of the American Academy of Ophthalmology, which delivers eye exams and care at no out-of-pocket cost for eligible seniors age 65 and older through its corps of more than 6,000 volunteer ophthalmologists.

2. Know the symptoms of vision loss.

Signs of vision loss may become apparent as reading, writing, shopping, watching television, driving a car and/or recognizing faces become more difficult. Vision loss that may be noticed by friends and family include missing, bumping into or knocking over objects, stepping hesitantly, and squinting or tilting the head when trying to focus.

3. Make eye-healthy food choices.

4. Quit smoking.

High blood pressure, cholesterol and blood glucose (sugar) levels all increase the risk of vision loss from an eye disease. Keeping these under control will not only help one’s eyes but also overall health.

6. Get regular physical activity.

Not only does 30 minutes of exercise a day benefit one’s heart, waistline and energy level, it can also do the eyes a world of good! Many eye diseases are linked to other health problems, including high blood pressure, diabetes and high cholesterol levels.

7. Wear sunglasses.

Exposure to ultra violet (UV) light raises the risks of eye diseases, including cataract, growths on the eye and cancer. Always wear sunglasses with 100 percent UV protection, and a hat while enjoying time outdoors.
