Over the last 50 years our focus of vision has been reduced to arm’s length because of computer work, recreation and video games. These changes can produce eyestrain, nearsightedness and suppressed vision. Computer users experience visual stress because of an increase in the number and complexity of eye movements and focus skills, poor lighting conditions, screen flicker rates, and extended hours in front of the screen.[1]
To avoid eyestrain try simple exercises like scanning objects in the room to increase eye flexibility and palming (placing your palms over your eyes for complete darkness for 15-20 seconds) to relax your eyes.
