Blue Light and Children’s Eye Health
Blue light is a high-energy visible light with a short wavelength between 380nm and 500nm. It can pass through the cornea and lens and reach the macula directly, potentially damaging light-sensitive cells over time.
Remember the BLINK Rule
Pediatric ophthalmologists recommend the BLINK rule to help protect children’s eyes during screen use.
Blink: Every 20 minutes, look at something far away for 20 seconds and blink several times to reduce eye strain.
Lubricate: Use artificial tears and consider a humidifier in dry environments.
Inches away: Keep at least an arm’s length distance from the screen and position it slightly below eye level.
Near device breaks: Take a 5 to 10 minute break every hour and avoid screens one hour before bedtime.
Know your sources: Always seek advice from doctors and nutrition professionals.
Lutein vs Zeaxanthin What’s the Difference
Lutein and zeaxanthin are carotenoids essential for eye health. The body cannot produce them, so they must be obtained through diet or supplements.
Both accumulate in the macula and act as natural blue light filters, supporting retinal health and reducing oxidative stress.
Other Eye Supporting Nutrients
Anthocyanins, astaxanthin, vitamins A, C, E, zinc, selenium, and omega-3 fatty acids all play supportive roles in maintaining eye health.
