The best way to prevent glaucoma is to take routine comprehensive eye exams and talk to an eye doctor about your risk factors to catch the disease early. Though preventing glaucoma isn’t always possible, early treatment can prevent significant vision loss. Talk to your doctor often about risks and treatments and encourage family members to get screened for glaucoma if you’re diagnosed. Generally, eating a nutritious diet rich in vitamins like vitamin A and getting regular moderate exercise may keep your eyes healthy for longer. Protecting your eyes from injury during sports, work, and home improvement projects can protect you from secondary glaucoma, too. Wear protective eyewear whenever neccesary. Remember: The best prevention is early detection.
