How Digital Devices
Affect Your Eyes
Screen time puts your vision at risk
Nearly 4 in 10 millenials spend at least 9 hours on digital devices each day
Filipinos spend 6 hours online in a computer and 3 hours on a mobile device
Most devices emit high-energy visible (HEV) or “blue light”, which has potential long-term effects to retinal cells.
47% of filipinos use more than one screen at a time.
The retina cannot regenerate or be replaced, Retinal cell damage puts your eyes at risk for long-term visual issues such as nearsightedness, farsightedness, astigmatism

Relief
Follow the 20-20 rule: look away from your screen every 20 minutes, for 20 seconds, at something 20 feet away to recharge eyes and normalize blink rate
Every 30 minutes, step away from the screen and stretch your neck, arms, and shoulders.
Rub your palms briskly together and place them over your eyes to soothe strain
Remember to blink once in a while when working
Prevention
Computer and laptops
should be used at arm’s length
Attach a glare reduction
filter to your screen
Adjust the brightness
of your device: a dim
screen makes it
harder for eyes to focus
Wipe your screens
regularly to reduce glare
If possible, adjust the
text size and contrast
on your device to
optimum levels
Screens should be directly
in front of your face and below your eye level
Lessen (but don’t eliminate)
light that competes with
your device screen
