Dry Eye in Children & Screen Use — Protecting Your Child's Eye Health

Yes — and an increasingly significant one. Dry eye disease has historically been considered predominantly a condition of middle-aged and older adults. That picture is changing. The dramatic increase in screen time among children and adolescents over the past decade has produced a corresponding increase in dry eye symptoms in younger age groups.

Children are not simply small adults when it comes to screen use and eye health. Several factors make them particularly vulnerable:

Immersive screen engagement Children tend to engage with screens — particularly games and video content — with intense concentration. This produces a more pronounced reduction in blink rate than many adult screen use patterns. A child absorbed in a game may blink as infrequently as three to four times per minute for extended periods.

Extended duration Screen time among children has increased substantially. Many children now spend four to six hours or more per day on screens across devices — smartphones, tablets, computers, and televisions. The cumulative daily exposure to reduced-blink conditions is significant.

Developing ocular surface The paediatric ocular surface is still maturing. The meibomian glands are present from birth but gland function develops through childhood and adolescence. Chronic reduced blink rate during this developmental period may have consequences for long-term gland health that are not yet fully understood.

Outdoor time deficit Reduced outdoor time — itself partly a consequence of increased screen use — removes the natural daylight exposure that supports healthy eye development and reduces the near work demands that drive blink rate reduction.

What are the signs in children?

Children often don't articulate eye discomfort clearly — they may not have a reference point for what comfortable eyes feel like. Signs to watch for include:

• Frequent eye rubbing
• Complaints of tired, sore, or itchy eyes — particularly after screen use
• Redness of the eyes or eyelid margins
• Screwing up or squinting at screens
• Avoidance of reading or screen use that was previously enjoyed
• Headaches associated with near work or screen use
• Blinking excessively or irregularly
• Crusting of the eyelids in the morning

These symptoms warrant an eye examination — and if dry eye is suspected, a proper ocular surface assessment.

What can parents do?

Manage screen time actively Current guidance from the Royal College of Paediatrics and Child Health recommends negotiating screen time limits with children based on age, with particular attention to screen use before bed. For eye health specifically, regular breaks from screens are more important than total daily limits — a child who takes a five-minute break every 30 minutes is in a better ocular surface position than one who uses screens for the same total time without breaks.

Encourage outdoor time Regular outdoor time benefits both eye development broadly and dry eye specifically — natural light and varied focus distances give the visual system a rest from the near work demands of screens.

Teach conscious blinking Older children can be taught to be aware of their blink rate during screen use and to take blink breaks — pausing briefly to blink fully several times. Making this a habit during screen use is a simple and effective protective measure.

Maintain lid hygiene where indicated If a child has blepharitis or significant lid margin disease, a gentle age-appropriate lid hygiene routine can make a meaningful difference to comfort.

Limit screens before bed Screen use in the hour before bed reduces sleep quality and exposes the eyes to prolonged reduced-blink conditions at a time when the ocular surface should be recovering. Establishing a screen-free period before bedtime benefits both eye health and sleep.

When to seek assessment

If your child is regularly complaining of eye discomfort, rubbing their eyes frequently, or showing signs of ocular surface irritation — particularly associated with screen use — a proper eye examination and ocular surface assessment is the right step. Dry eye in children is treatable, and addressing it early is better than allowing symptoms to persist and worsen.
