Tips to maintain eye health
Wearing sunglasses: Sunglasses have an important role in protecting against ultraviolet rays as they block them by 99 to 100 percent, delay the occurrence of cataract and prevent damage to the retina, and they also protect the delicate eyelid skin to prevent both wrinkles and skin cancer around the eyes. .
Smoking cessation: Smoking is directly linked to many eye problems and diseases, including age-related macular degeneration (AMD). Studies show that current smokers and ex-smokers are more likely to develop age-related macular degeneration disease than people who have never smoked.
Proper nutrition: A lack of vitamins can affect retinal function. As our mothers have always told us that eating carrots improves vision, but not carrots alone but rather a variety of vegetables, especially leafy greens, they should be an important part of your diet.
Be careful of eye fatigue: If you spend a lot of time at the computer or stare at your phone for a long time, you can easily not forget about blinking, which has an important role in moisturizing the eye, and forgetting this may damage your eyes and cause dry eyes.
