One should try to have normal blinking while working on computer, should look away from screen after every 10 minute , should take rest for 10 minute after every 2 hours& should wear antiglare glass. Software professionals should use lubricating eye drops 4-5 times daily (Systane ultra)&genteal gel once at bed time.
