Screens are part of everyday family life now whether we like it or not from homework on a laptop to cartoons on a tablet. It is a tricky one to navigate for modern day parenting because we all have different views on it. As a mother myself, I don’t let my two children have much screen time at all; the only screen they are allowed is a bit of TV time and at the weekend, a laptop to do their homework.
In this article you will find some of the latest government guidelines for young children, plus practical eye-health habits parents can actually stick to.
What does safe screen time look like?
When parents ask “How much screen time is safe?” tough one to answer but eye-care professionals usually look beyond the minutes and focus on:
- Distance (how close the screen is)
- Duration (how long without a break)
- Dryness (reduced blinking = irritated eyes)
- Daylight (outdoor time supports healthy visual development)
- Downtime (especially before bed)
That’s because screens don’t “damage” eyes in a simple, instant way. It is a lot more complex than that but heavy near work and long, unbroken sessions can most certainly contribute to discomfort (digital eye strain) and may increase the risk of myopia in children.
UK guidance for under-5s: what the government now recommends
In March 2026, very recently, the UK government published evidence-backed guidance for parents of under-5s.
The key points are pretty practical:
Under 2s: avoid screen time except shared activities that encourage bonding and interaction (for example, video calling family).
Ages 2–5: aim for no more than 1 hour a day.
Avoid screens at mealtimes and in the hour before bed.
Choose slow-paced, age-appropriate content, and ideally watch together and talk about what’s on screen.
Although this guidance is not specifically focused on eye health, it offers sound advice for maintaining eye health by reducing prolonged solo close-up watch time and protecting sleep which is so important for young developing brain.
What screen time can do to children’s eyes and what it usually looks like at home?
1) Digital eye strain (yes, kids get it too)
Children can experience classic “screen fatigue” symptoms, including:
- Sore, tired or itchy eyes
- Headaches (especially after schoolwork)
- Blurred vision that comes and goes
- Watering or dry-feeling eyes
- Squinting, rubbing eyes, or losing place when reading
Why it happens: when we focus on screens, we often blink less and stare for longer. Add close viewing distances and you’ve got a perfect recipe for strained eyes.
2) Dryness and irritation
Even if your child doesn’t complain, you might notice:
- Red rims
- Frequent blinking
- Eye rubbing
A dry, heated classroom or bedroom plus lots of near work can make this worse.
3) Myopia (short-sightedness) risk: the bigger-picture concern
Myopia is influenced by genetics, but lifestyle matters too. UK optical bodies increasingly emphasise two protective habits:
- More outdoor time
- Less intense, prolonged near work
The Association of Optometrists (AOP) highlights that children who spend more time outdoors are at lower risk of myopia, and points to two hours outdoors a day as an ideal target. Did you know that babies are born with long vision? Allowing them to see their mothers and feel secure? It is important for them to maintain this long vision for as long as possible, and the best way to achieve this is through outdoor time, which helps work those eye muscles.
What’s “safe” in real life? A simple UK-friendly screen routine by age
This isn’t about perfection, it’s about building habits that reduce eye strain and protect sleep.
Under 2s
- Keep screens for interactive, shared moments (e.g., video calling grandparents)
- Prioritise play that builds visual skills: stacking, sorting, picture books, outdoor walks
Ages 2–5
- Use the government’s “aim for no more than 1 hour/day” as your anchor
- Break it up into short sessions (think: 10–20 minutes)
- Keep screens out of bedrooms, and avoid them before bed
Primary school age (rough guide)
- Avoid long, unbroken sessions (especially after school)
- Balance homework screens with outdoor time
- Keep a consistent “screens off” wind-down before bed
The “eye-safe” checklist: 8 practical tweaks that make a big difference.
1) Make distance non-negotiable
- Tablets/phones: aim for at least forearm length
- Laptops/desktops: about an arm’s length
If your child is constantly moving their device closer, it’s worth booking an eye test.
2) Use the 20-20 idea
Every 20 minutes, look away for 20 seconds. For younger kids, turn it into a game: “Find something far away that’s blue.”
3) Prioritise outdoor time daily
The AOP points to two hours outdoors a day as ideal. That can be:
- Walk to school and park time
- Scooting
- Football in the garden
- Nature walk
4) Protect the last hour before bed
The UK government guidance for under-5s specifically calls out avoiding screens in the hour before bed.
Swap it for:
- Story and cuddle
- Audiobook
- Puzzle or colouring
5) Set up a “blink-friendly” screen environment
- Good lighting (avoid glare)
- Screen slightly below eye level
- Encourage blinking and mini-breaks
6) Watch for the sneaky signs of vision problems
Book a sight test if you notice:
- Squinting
- Sitting very close to screens
- Head tilting
- Complaints of headaches
- Avoiding reading
7) Don’t forget the free NHS eye test
The AOP advises booking a child’s sight test every two years from age three, or more often if your optometrist recommends it.
8) Remember: content and co-viewing matter
The under-5s guidance highlights that slow-paced content and watching with an engaged adult is better than fast, swipe-style videos watched alone. From an eye health point of view, co-viewing also helps you spot when your child is too close, rubbing eyes, or zoning out.
Quick FAQs parents always ask
Do screens permanently damage children’s eyes?
Screens aren’t typically thought to cause permanent damage on their own, but heavy, close-up, unbroken screen use can trigger digital eye strain, disrupt sleep, and may contribute to myopia risk when it replaces outdoor time.
Are tablets worse than TVs?
Often, yes because tablets and phones are held much closer, which increases focus demand. A TV across the room is generally less intense for the eyes.
Should my child wear blue light glasses?
For most children, the bigger wins are behavioural: distance, breaks, outdoor time, and screen-free wind-down before bed. If sleep is the issue, reducing evening screen exposure (and brightness) tends to matter more.
