Some of the ways to improve bad eyesight include eating foods rich in nutrients such as zinc and omega-3 fatty acids, quitting smoking and wearing sunglasses, explains WebMD. People should avoid staring at the computer screen for too long as this can cause blurry vision and dry eyes. The screen should be positioned so that the eyes are level with the top of the monitor or use an anti-glare screen.
Having good vision starts with eating foods rich in certain nutrients, explains WebMD. Foods that contain vitamins C and E can help in preventing age-related vision problems like cataracts and macular degeneration. Other foods that promote good eye health include green leafy vegetables such as collards, kale and spinach; tuna, salmon and other oily fish; nonprotein sources such as egg, beans and nuts; and citrus fruits and juices such as oranges.
Smoking increases the chances of getting macular degeneration, optic nerve damage and cataracts, explains WebMD. Wearing the right sunglasses protects the eyes from ultraviolet rays, as high levels of exposure may lead to cataracts and macular degeneration. People working with hazardous materials should also wear protective goggles or safety glasses to prevent physical or chemical damage to the eyes.
