No need: Just make sure to blink frequently and look away for a brief time or give yourself short breaks. We tend to stare at the monitor and forget to blink. Blinking stimulate tear production otherwise you will dry up. When we look up close we contract our eye muscles which after a while it will cause eye strain. You need to look away to relax muscles.
