Early detection of vision problems may offer more effective treatment options: Have periodic eye exams (every 2-3 years for healthy patients under 50, yearly for patients over 50 or those with known health risk factors). Know your family's history for any eye problems. Follow a healthy lifestyle. Eat a nutritious diet for eyesight. Wear durable eye protection when involved in activities that could cause traumatic risk to your vision, such as sports, dealing with firearms, playing paintball. Occupations where hammering, cutting, sawing, drilling, or working overhead are other examples.
