Always wash your hands before you touch your eyes. Your fingers are covered with bacteria because your hands touch surfaces that other people have touched. If you touch your eyes without washing your hands, you will transfer bacteria to your eyes and cause irritation or even an infection. Therefore, before touching your eyes, wash your hands with soap and water.
If you work for long periods of time on a computer, protect your eyes by taking frequent breaks. You might have noticed that your eyes often feel strained, tired and itchy during regular working hours. This is probably a good indication that you're overworking them. Get up and stretch for a few minutes, offering your eyes some time away from the screen.
