2. INTRODUCTION

3. DEFINITION Digital Eye Strain (DGE) Also referred as Computer Vision Syndrome (CVS) A group of eye- and vision-related problems result from prolonged computer, tablet, e-reader, and cell phone use

4. Prevalence of DGE/CVS 80% American adults report using digital devices for more than two hours/day 59% report experiencing symptoms of DGE

5. pathophysiology When work on a digital device, the eyes have to focus and refocus continously Move back and forth as one read and likely have to look down at papers or other devices and then back up to the screen Constantly reacting to images moving and changing, shifting focus, sending rapidly varying images to the brain, and its worsen with add contrast, flicker, and glare Less frequently blink

6. Risk factors Spend a few hours a day at a computer or on a digital device Viewing computer/digital device screen at an improper distance/angle Poor posture while using the computer/digital device Inadequate lighting causing increase glare from digital device Don’t take breaks while working Have vision problems not fully corrected with glasses or contact lenses (even minor changes in prescription) Don’t blink frequently enough while using the digital devices

7. Symptoms Eye fatigue/tired eyes Headaches Tearing Blurry vision/double vision Eye discomfort Dry eyes/ itchy eyes / irritation Neck pain / shoulder pain Symptoms may vary in frequency, severity, and quantity

8. Treatment Change how to use the computer

9. Treatment Location of computer screen center of the screen 4-5 inches below eye level 20-28 inches from the eyes

10. Treatment Lighting position the screen to avoid glare (from overhead lighting or windows) Anti-glare screens Consider using screen glare filter, if there is no way to minimize glare from light sources

11. Treatment Seating position chair should be comfortably padded and comfort to the body Chair should be adjusted so the feet rest flat on the floor

12. Treatment Rest breaks 15 minutes after 2 hours of continous computer use 20/20/20 rule Blinking Effort to blink frequently Use artificial tears

13. Treatment Adjust the devices raise the contrast make text larger Change brightness: lighter/darker than the surroundings Lower the color temperature, giving less blue light

14. Treatment Correct the refractive error properly
