Vision loss or change can happen to anyone, and can go unnoticed if you do not take some of the necessary steps to ensure eye health and prevent vision loss. 

Have you eyes checked: Many serious diseases have no symptoms, and early detection is critical to ensuring you can receive treatment that could save your sight. 

Quite smoking: People who smoke are up to four times more likely to develop AMD. 

Eat healthy and get fit: Diets high in fats and low in nutrients heighten the risk of developing AMD. Keep active and increase your intake of omega-3 fatty acids and leafy greens. 

Protect your eyes from sunlight: Exposure to sunlight is associated with a higher risk of developing AMD and cataracts. Wear sunglasses with at least 99 percent UVA and UVB protection whenever you're outside. 

Wear eye protection: When playing sports or working with power tools, protect your eyes with safety googles or glasses. 

Consider vitamin supplements: If you've been diagnosed with dry AMD, talk to your optometrist about high-dosage vitamin supplements that are effective in lowering the risk of vision loss. 

Prevent diabetes: People with diabetes are at a higher risk of developing diabetic retinopathy (one of the major eye diseases that cause vision loss) and other vision problems. 

Manage your diabetes: To lower your risk of diabetic retinopathy, it's important to control your blood pressure, sugar and lipid (fat) levels.

Keep alcohol to a minimum: Heavy drinking of alcohol is a known risk factor for developing cataracts and other eye diseases. 

Educate yourself: Many eye diseases are related to hereditary or ethnicity, so getting to know your family history can help you understand your risk.
