Between homework, apps and downtime, screens are part of everyday life for kids and teens. They open up great opportunities, but long screen sessions can bring tired eyes, poorer sleep and trouble focusing.
This guide covers what parents need to know about screen time and blue light, and simple ways to help.
1. Blue light and young eyes
Blue light is a high-energy part of visible light. The sun is the biggest source, but phones, tablets, computers and LED screens emit it too.
- Digital eye strain: long screen sessions can cause dry or itchy eyes, blurred vision and headaches, mostly because we blink less and focus up close for too long.
- Sleep: screen light in the evening can delay melatonin and make it harder to fall asleep.
- Focus fatigue: staring at small text for long periods tires the eyes.
2. Screen-time habits that help
The 20-20-20 rule
Every 20 minutes, look at something 20 feet away for 20 seconds. It lets the focusing muscles relax.
Screen-free bedrooms and cut-off times
Put devices away 1–2 hours before bed and keep them out of bedrooms overnight.
Time outdoors
Daylight and distance vision are good for growing eyes. Research links more outdoor time with a lower risk of developing short-sightedness (myopia). Aim for at least an hour outside a day, with sunglasses on sunny days.
3. Screen glasses for teens
When screen time can't be avoided, for homework for example, glasses with blue-light filtering lenses can make long sessions more comfortable. They work best alongside breaks and good habits, not instead of them.
OLIVIO&CO screen glasses, sized for ages 12 and up, offer:
- Blue-light filtering: lenses filter up to 40% of blue light from digital screens while keeping colours natural.
- Light, flexible TR90 frames: bend instead of breaking and stay comfortable through long homework sessions.
- Mediterranean-inspired colours in an easy oval shape.
