Dry eye in children is an increasing concern that can affect their comfort and vision. Recognizing symptoms early is crucial for effective management and treatment.
Dry eye in children is a condition where there is either an insufficient production of tears or the tears evaporate too quickly, leaving the eyes feeling uncomfortable and irritated. Although this condition is more common among adults, an increasing number of children are experiencing dry eye symptoms. It is important to address these issues early, as persistent discomfort can affect a child’s vision and daily activities such as schoolwork.
Dry eye occurs when the tear film that protects and lubricates the surface of the eye becomes unstable. In children, this instability may lead to symptoms that include a burning sensation, a gritty feeling, mild redness, or even blurry vision. Since kids are not always able to precisely communicate what they feel, it becomes essential for parents and caregivers to notice subtle signs of discomfort.
The condition is sometimes referred to as pediatric dry eye syndrome or pediatric evaporative dry eye because the tears evaporate too quickly. Even though dry eye is considered fairly uncommon in children, recent observations suggest its prevalence is slowly increasing, possibly due to lifestyle changes such as prolonged screen time. Our eye doctors emphasize that managing dry eye early can help in preventing further complications in a child’s vision.
There are several factors that can contribute to the development of dry eye in children. While many causes are similar to those seen in adults, some specific considerations are unique to kids and their environments. Recognizing these factors is a key step in helping children find relief.
Here’s one of the most common reasons for dry eyes in kids today. With the advent of smartphones, tablets, and computers, children are spending more hours than ever looking at screens. Studies have shown that when a child is focused on a screen, their blink rate significantly decreases. A lower blink rate increases the evaporation of tears from the eye’s surface, causing discomfort and instability in the tear film.
Our eye doctors have noted that outdoor activities appear to be protective against dry eye. Encouraging children to take breaks from screens is not only beneficial for their overall eye health but also helps reduce the risk of developing dry eye symptoms.
Allergies are another important factor. Many children suffer from seasonal allergies or are exposed to common allergens such as pet dander and dust. Ocular allergies can trigger inflammation on the surface of the eye, leading to tear film instability. When the ocular surface becomes inflamed, it may not produce tears of the necessary quality and quantity needed to protect the eye.
This inflammation can also extend to conditions like blepharitis, where the eyelid margins become irritated. Such inflammatory conditions not only disrupt the tear film but also contribute to a constant cycle of discomfort which might be mistaken for simple eye strain.
Nutrition plays a significant role in eye health. A deficiency of vitamin A, for example, can change the cellular makeup of the ocular surface, a condition sometimes referred to as xerophthalmia. When the cells lining the eye are not functioning properly, tear production can diminish, leading to dry eye syndrome.
Children who have malabsorption issues or who follow strict diets without sufficient nutrients may be at higher risk. It is essential for parents to ensure that their child’s diet includes foods rich in vitamins and omega-3 fatty acids, such as fish, flaxseed, and certain vegetables, which support healthy tear production.
Some medications aimed at treating common childhood conditions can inadvertently cause or worsen dry eye. For instance, certain systemic or topical medications prescribed for acne or allergies may have drying effects on the eyes. Additionally, rare autoimmune diseases such as Sjögren’s syndrome or even chronic conditions like diabetes and thyroid abnormalities, although less common in children, may contribute to dry eye symptoms.
It is important to consider that sometimes dry eye in children can be a secondary symptom related to a more serious medical condition. If the symptoms persist even after addressing the usual environmental or dietary causes, consulting with our eye doctors can help rule out any underlying issues.
While contact lenses are not as common in very young children, older kids and teenagers who require vision correction might use them. Extended use of contact lenses, particularly orthokeratology lenses designed to reshape the eye, can disturb the tear film. This disturbance can lead to symptoms of dry eye, especially during the initial period of wearing the lenses. Regular eye examinations are crucial for assuring that any contact lens-related eye dryness is properly managed.

Children may not always be able to articulate exactly what they are experiencing. Therefore, it is vital for parents and caregivers to watch for visual or behavioral signs indicating that a child’s eyes might be dry. Being observant can lead to early intervention and relief.
Each of these symptoms can be mild on its own, but when several appear together, it may be time to seek guidance from our eye doctors. Early detection helps in creating appropriate management strategies tailored to the child’s needs.
Digital screens have become an integral part of a child’s daily routine, whether for educational purposes or leisure. However, the constant visual focus required by these devices can lead to a significant decrease in blink rate. Normally, blinking occurs about 15 times a minute, but when engrossed in screen activities, this number can drop considerably.
This reduced blinking means that the natural lubrication provided by tears is not distributed as effectively. Consequently, the tear film may break up too quickly, leaving areas of the eye exposed to air and evaporation. Parents might notice that their children tend to take fewer breaks during computer or tablet use, leading to an increased risk of developing dry eye symptoms.
Encouraging periodic breaks and setting limits on continuous screen use can help maintain a healthier tear film. Simple guidelines, such as reminding your child to blink frequently or applying the 20-20-20 rule (taking breaks every 20 minutes to look at something 20 feet away for at least 20 seconds), can be very effective.
