Practical steps to reduce blue light exposure and protect your eye health
Follow the 20-20-20 Rule
Every 20 minutes, look at something 20 feet away for at least 20 seconds to reduce eye strain.
Use Night Mode
Enable night mode or blue light filters on your devices, especially in the evening.
Blue Light Blocking Glasses
Consider using blue light blocking glasses, particularly if you spend long hours on screens.
Natural Light Exposure
Spend time outdoors in natural light daily to help regulate your circadian rhythm.
Device Distance
Keep screens at arm's length (about 25 inches) from your eyes when possible.
Screen-Free Time Before Bed
Avoid screens for at least 1-2 hours before bedtime to improve sleep quality.
