Computer Glasses for Children: From What Age and What Doctors Advise

In short: according to the American Academy of Ophthalmology and the American Academy of Pediatrics, separate blue light glasses are usually not needed for children: there is no evidence that blue light from ordinary screens harms children's eyes. The 20-20-20 rule, time outdoors, breaks and a vision check with a doctor help. If a child complains about their eyes or sees poorly, they need an eye doctor, not "computer" glasses.

What ophthalmologists say

The American Academy of Ophthalmology notes that blue light does not "blind" children and is not the cause of rising short-sightedness, and natural sunlight contains far more blue light than screens. AAO article on myths about children's eyes. The American Academy of Pediatrics also sees no evidence of harm from the blue light of ordinary screens to children's eyes, and special screen glasses are generally not needed.

Children may complain of dryness, eye tiredness, headaches and blurred vision, but such symptoms are usually temporary and do not mean the child needs glasses. AAO: screens and children.

From what age

There is no age limit for "from what age blue-filter glasses" because their benefit is not proven. If the question is vision correction, a doctor prescribes it at any age.

What actually helps

1. The 20-20-20 rule. Every 20 minutes look at something 6 metres away for at least 20 seconds. For children make it a game or a timer.
2. Breaks and movement. See how long to play without a break.
3. Time outdoors. According to research, outdoor activity is linked to a lower risk of developing short-sightedness in children. Ask a doctor for specific advice.
4. Distance and posture. The screen at arm's length, see monitor height and posture.
5. Lighting. Without glare, see monitor brightness.
6. Sleep. No screens 30–60 minutes before bed, see late gaming and sleep.
7. Limiting time. The Academy of Ophthalmology does not name a universal number of hours; discuss a routine with a paediatrician and the family.

When to see an eye doctor

• the child squints, leans towards the screen, rubs their eyes or complains of headaches;
• blurred vision that does not go away;
• a squint, watering or redness;
• there is short-sightedness or other eye disease in the family;
• a routine vision check on a doctor's advice.

Early diagnosis helps because vision problems can be corrected.

Should you buy "children's" computer glasses

Not necessarily. If a child needs correction, the doctor prescribes glasses with the right power, see computer glasses with or without prescription. Non-prescription glasses for children without vision problems have no proven benefit.
