Aging and vision problems don’t have to go hand and hand. Maintaining a healthy lifestyle that includes exercise, weight management, sun protection and not smoking can help you age-proof your vision and avoid some of the eye diseases common in older people—such as glaucoma, cataracts and macular degeneration.

While some people’s bad eyesight can be addressed with corrective lenses or surgery, not all vision problems are correctable. Low vision, for example, is a common chronic problem that interferes with quality of life. And though it can’t be corrected, there are services available that can help make daily activities easier.

All age-related vision problems are best treated when they’re caught early. Practice prevention by getting regular eye exams and encouraging loved ones to do the same. And be sure to tell your doctor about new symptoms.
