The human body is a wonderful machine, but it’s different from many other machines. Our systems are related in complex and sometimes mysterious ways. Solving the problem of a car’s flat tire usually requires nothing more than changing the tire. Replace a dead battery in your tape recorder, and you'll soon be listening to your favorite books and music again.

When something goes wrong in the human body, many systems may be involved. And the solution isn't usually as easy as replacing a part.

The eye, for example, can’t be replaced. Cornea transplants are possible, but this involves replacing one small part of the eye. Many people don’t realize how vision problems can be related to other health issues. Here are some brief examples. Talk with your doctor about any of the information that you think may pertain to your individual situation.

Diabetes:

• Health Risks: According to the American Diabetes Association, diabetes has reached epidemic proportions in the U.S., with more than 17 million estimated to have it. Diabetes is now the nation’s sixth leading cause of death. Doctors believe diabetes is the #1 risk factor for cardiovascular disease (heart disease and stroke).
• Vision Risks: Diabetes is one of the leading causes of blindness. Nearly half of all diabetics will develop diabetic retinopathy to some degree during their lifetime.
• Risk Reduction: The Diabetes Prevention Program released findings in 2002 showing that modest weight loss (5 to 7 percent of body weight) and increased physical activity (such as brisk walking for 30 minutes per day) can cut a person’s risk of developing diabetes by more than half. Start making these changes today!

Nutrition:

• Vitamin Deficiency: A good diet is necessary for maintaining healthy eyes. Even if eye disease has begun, a healthy diet is important since it may help slow the disease process. A diet high in antioxidants won’t cure your eye problems, but it may slow some of the degenerative processes that lead to macular degeneration and cataracts, for example.
• Vitamin Supplements: It’s best to get as many nutrients as possible through your diet. Fresh foods are cheaper and more enjoyable than pills! And your entire body, not just your eyes, will benefit from good nutrition. Talk with your doctor about whether additional supplements may be necessary.

Exercise:

• Risk Reduction: Moderate physical exercise (such as brisk walking for 30 minutes each day) can dramatically cut the risk of developing diabetes and cardiovascular disease.
• Weight Control: Exercise helps with weight reduction and control, especially when paired with a healthy diet rich in sources of vitamins and minerals.
• Other Benefits: Moderate exercise can help build or maintain muscle and bone (important in fighting osteoporosis). Many people with balance problems find that exercise and strengthening help improve balance and prevent injuries from falls.

Smoking:

• Reduce Risk: Smoking is a major risk factor for cardiovascular disease and cancer, and is thought to be a significant factor in eye health. It’s believed to be a risk factor for macular degeneration. Stopping smoking has definite benefits for any age, not just for younger people.
• Reduce Second-hand Risk: Second-hand smoke is also a significant risk factor to other people around you. If you smoke, quit. If you don’t smoke, don’t start.
