How to Preserve Your Eyesight

Many Americans aren't aware of the dangers of eye diseases that can develop as they age. Eye diseases can include glaucoma, cataracts and visual loss due to diabetes. It's estimated that 43 million Americans will suffer from such diseases by 2020, reports the American Academy of Ophthalmology. Without treatment, blindness can result. However, it's possible to help protect your eyes as you age and prevent debilitating vision loss.

Instructions

• 1

  Know your family history and whether family members suffer from any eye diseases. For example, African Americans over 40 have a higher risk for developing eye diseases, indicates All About Vision.

• 2

  See your doctor.

  Notice any visual disturbances you develop, which can include floaters or double vision. Visit your ophthalmologist.

• 3

  Always protect your eyes.

  Wear glasses if you have an eyeglass prescription. Use sunglasses to shield your eyes against UV light, recommends Bausch and Lomb.

• 4

  Use glaucoma eye drops when you've been diagnosed with the disease. Even if you haven't developed symptoms, adhering to your doctor's treatment plan can prevent irreversible eye damage, according to the Glaucoma Research Foundation.

• 5

  Take care of your diabetes.

  Treat your diabetes. While vision disturbances occur when you're first diagnosed with diabetes, continued visual disturbances require a modification in treatment, according to the Joslin Diabetes Center.

• 6

  Keep your blood pressure under control.

  Monitor your blood pressure with diabetes. High blood pressure can cause damage to the blood vessels in your eyes. Aim for a blood pressure of 130/80, advises the Joslin Diabetes Center.

• 7

  Keep your body fit.

  Exercise more. Exercise increases your blood flow, as well as helping to reduce diseases such as macular degeneration. Macular degeneration causes blurring and blind spots.

• 8

  Eat foods that will benefit your sight.

  Incorporate healthier foods into your diet. Omega-3 fatty acids found in foods such as fish can help reduce the risk of developing cataracts. Foods containing antioxidants, such as red berries, and leafy green vegetables can also provide protection for your eyes.
