WHAT CAUSES DIGITAL RELATED EYE STRAIN?
Normally, humans blink about 15 times a minute, but studies show we blink half to a third that often while using computers and other digital screen devices, whether for work or play. Extended reading, writing or other intensive “near work” can also cause eye strain.
Eye Ergonomics Tips:
1. Sit about 25 inches, or arm's length, from the computer screen. Position the screen so your eye gaze is slightly downward.
2. Reduce glare by using a matte screen filter if needed.
3. Take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away, for at least 20 seconds.
4. Use artificial tears to refresh your eyes when they feel dry. Consider using a humidifier.
5. If a screen is much brighter than the surrounding light, your eyes have to work harder to see. Adjust your room lighting and try increasing the contrast on your screen to reduce eye strain.
