If you use your computer regularly, make sure that the computer monitor is correctly positioned to minimize eye strain. It should stand at eye level or slightly below it but no more or less than that. In addition, staring at a computer screen limits the number of times you blink every minute, according to a recent study, people who stare at their computer blink 3 times less than people who don’t.
Adjust both your screen monitor and the brightness of the screen to a level that feels comfortable.
Take regular breaks while working. Take a 10-minute break every hour and do something that doesn’t involve staring at a screen.
5. Keep your eyes clean.
