Can Screen Time Affect a Child’s Vision?

Screens are everywhere - from tablets and smartphones to laptops and classroom smartboards. While technology offers educational and social benefits, many parents wonder how increased screen time may affect their child’s vision. The concern is valid: excessive screen use can contribute to eye discomfort, visual fatigue, and long-term vision issues if not properly managed.

Understanding how screen time impacts children’s eyes - and how comprehensive eye exams play a role in protecting their vision - can help parents make informed choices for their child’s eye health.

How Screen Time Affects Children’s Eyes

Children often use screens for long periods without breaks. Unlike adults, they may not recognize symptoms of eye strain or know when to rest their eyes. Prolonged screen use can lead to a group of symptoms often referred to as digital eye strain, which may include:

• Eye fatigue or discomfort

• Headaches

• Blurred vision

• Dry or irritated eyes

• Difficulty focusing

When children stare at screens, they tend to blink less frequently, which can dry out the eyes and contribute to irritation. Poor posture and improper screen distance can also increase strain on the eyes and neck.

Screen Time and Myopia (Nearsightedness)

One of the biggest concerns associated with increased screen use in children is myopia, also known as nearsightedness. Myopia occurs when distant objects appear blurry while close objects remain clear. This condition has become increasingly common in children over the past few decades.

Research suggests that extended near work - such as reading, using tablets, or playing on smartphones - may contribute to the development and progression of myopia. When combined with limited time spent outdoors, the risk appears to increase. Natural outdoor light and distance viewing play an important role in healthy visual development, especially in young children.

If left unmanaged, myopia can worsen over time and may increase the risk of more serious eye conditions later in life, such as retinal detachment or glaucoma.

Signs Your Child May Be Experiencing Vision Problems

Children don’t always realize their vision isn’t normal. Parents should watch for signs that may indicate a vision issue, including:

• Squinting or covering one eye

• Sitting very close to screens or holding devices too close

• Frequent eye rubbing

• Complaints of headaches or tired eyes

• Difficulty concentrating on schoolwork

• Declining academic performance

If you notice any of these behaviors, it’s important to schedule an eye exam as soon as possible.

The Importance of Comprehensive Eye Exams for Children

Comprehensive eye exams are essential for detecting vision problems early - often before symptoms become obvious. These exams go beyond basic vision screenings performed at schools or pediatric offices. A comprehensive exam evaluates eye health, visual acuity, eye coordination, focusing ability, and early signs of conditions like myopia.

Early detection allows for timely treatment, which may include prescription glasses, lifestyle recommendations, or myopia management strategies designed to slow progression. Addressing vision problems early can support a child’s learning, development, and overall quality of life.

Tips to Reduce the Impact of Screen Time

While screens are a part of modern life, parents can take steps to help protect their child’s vision:

• Encourage regular breaks using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds

• Ensure screens are positioned at a comfortable distance and slightly below eye level

• Promote outdoor play and physical activity

• Limit recreational screen time when possible

• Make sure your child has proper lighting while using screens

These habits can help reduce eye strain and support long-term eye health.
