  1. Too much screen time. If you work for long hours on the computer or read on your smartphone, your eyes will feel dry, blurry, and have other health concerns. So, if you spend too much time on digital screens, your eyesight can be affected. If you need to work for a long time on the computer or other digital screens, you can try to wear screen protection glasses.
  2. If you don’t drink enough water, your eyes are more likely to become dehydrated. This will result in puffy, dry, red eyes, leading to bad eyesight.
  3. Bad eyesight can be caused by the food you intake. A bad diet is bad for your eyes. Foods our eyes love include leafy greens, eggs, nuts, and seafood.
