Age-related macular degeneration is a blinding eye disease, and there are two types of this disease: dry and wet. Dry macular degeneration predominates in patients with early manifestations of night vision impairment and visual instability. It also presents with vitreous warts. As the disease progresses, the retina becomes thinner. The vitreous warts fuse with pigment abnormalities and the effect on central vision is aggravated, but the visual acuity is generally stable at about 0,5. Wet macular degeneration is the appearance of an abnormal vascular membrane under the retina, often accompanied by hemorrhage, with vision loss. Dry macular degeneration has the risk of developing into wet. Therefore, controlling dry macular degeneration is an important means of preventing vision loss. Although there is no way to cure dry macular degeneration, there are some ways to slow down its development: 1. have regular eye examinations; 2. take antioxidant supplements such as lutein; 3. eat a balanced diet with more fruits and vegetables, especially green vegetables such as spinach and kale; do not eat too greasy; 4. wear protective sunglasses that protect against ultraviolet rays; 5. do not smoke; 6. strengthen exercise.
