In today’s digital age, children are exposed to screens at a younger age than ever before. With tablets, computers, and smartphones becoming part of daily life, understanding how screen time affects children’s eye health is essential for parents. Dr. Andrew Satran of Advanced Pediatrics of Rockland in Pomona, NY, discusses the common vision problems children may face, the potential impacts of prolonged screen exposure, and strategies for preserving eye health in a screen-focused world.

Why Children’s Eye Health Matters

Good vision is fundamental to a child’s development, as it directly influences their ability to learn, interact, and participate in daily activities. Undiagnosed vision issues can lead to difficulties in school, lower confidence, and challenges in sports and other physical activities. While some eye conditions are hereditary or developmental, lifestyle factors, such as screen time, also play a significant role in children’s vision health.

Regular eye exams are crucial for identifying and addressing any potential issues early on. Eye health assessments, often starting around age three, allow professionals like Dr. Satran to detect common vision problems and recommend corrective measures if needed.

Common Vision Problems in Children

1. Nearsightedness (Myopia)
   Myopia, or nearsightedness, is increasingly common among children. With this condition, objects nearby appear clear, while distant objects are blurry. Early signs of myopia include squinting, difficulty seeing distant objects, and sitting too close to screens or books. Research suggests that increased time indoors and on screens is contributing to a rise in myopia cases.
2. Farsightedness (Hyperopia)
   Hyperopia, or farsightedness, is less common in young children but still affects a significant number. It causes difficulty focusing on nearby objects. Signs include headaches, eye strain, and avoidance of reading or other close-up activities. Unlike myopia, hyperopia is often present from birth and can improve as a child grows.
3. Astigmatism
   Astigmatism results from an irregularly shaped cornea, causing blurry vision at all distances. Symptoms include difficulty reading, eye discomfort, and frequent squinting. Astigmatism is generally detected during a routine eye exam and can be managed with corrective lenses.
4. Amblyopia (Lazy Eye)
   Amblyopia, or lazy eye, develops when the brain favors one eye over the other, leading to reduced vision in the weaker eye. Early treatment is essential, as it can lead to long-term vision impairment if left untreated. Treatment often includes patching the stronger eye to strengthen the weaker one.
5. Strabismus (Crossed Eyes)
   Strabismus occurs when the eyes do not align properly. One eye may look straight ahead while the other turns inward, outward, up, or down. If not corrected, strabismus can lead to amblyopia. Treatment options include corrective lenses, vision therapy, and, in some cases, surgery.

The Impact of Screen Time on Children’s Vision

Screen time is an unavoidable part of modern life, and while technology offers valuable learning and entertainment tools, excessive use can strain young eyes. Prolonged screen exposure has been linked to several eye health issues in children, including:

• Digital Eye Strain: Staring at screens for extended periods can cause symptoms like eye discomfort, dryness, and blurred vision. Children may not be able to communicate these symptoms effectively, making it essential for parents to monitor screen time.
• Blue Light Exposure: Screens emit blue light, which can disrupt sleep cycles and potentially contribute to eye strain. Although research on the long-term effects of blue light is ongoing, limiting exposure, especially before bed, can help minimize any potential risks.
• Reduced Blinking and Dry Eyes: When focused on screens, children tend to blink less frequently, which can lead to dry eyes and discomfort. Ensuring regular breaks can help mitigate this effect.
• Myopia Progression: Studies have shown a link between increased screen time and the progression of myopia in children. Spending more time outdoors has been found to reduce the risk of developing or worsening myopia, as natural light helps regulate eye growth.

Screen Time Recommendations and Tips for Parents

1. Follow the 20-20-20 Rule
   To reduce eye strain, encourage children to follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps relax the eye muscles and prevents prolonged strain.
2. Prioritize Outdoor Activities
   Studies indicate that outdoor time, especially in natural sunlight, plays a role in preventing myopia progression. Encourage your child to spend at least one hour a day outside, participating in activities that don’t require close-up focus.
3. Limit Screen Time
   The American Academy of Pediatrics (AAP) recommends no screen time for children under 18 months (except for video calls) and no more than one hour per day for children aged 2-5. For older children, the AAP advises setting consistent limits to prevent excessive screen exposure.
4. Adjust Screen Settings
   Reducing screen brightness, increasing text size, and using devices with anti-glare screens can lessen eye strain. Additionally, many devices offer “night mode” or “blue light filter” options, which can reduce the amount of blue light emitted by the screen.
5. Encourage Proper Posture and Distance
   Ensure that your child maintains a comfortable viewing distance from screens—about an arm’s length for computers and handheld devices. Good posture and ergonomics can also reduce eye and neck strain.

Recognizing Signs of Vision Strain or Problems

Since children may not always recognize or communicate their eye discomfort, parents should watch for signs that may indicate vision strain or problems, such as:

• Frequent rubbing of the eyes
• Complaints of headaches, especially after screen use
• Squinting or closing one eye to see better
• Avoiding activities that require focus, like reading or puzzles
• Difficulty maintaining focus on schoolwork or screens

If you notice any of these signs, consider scheduling an eye exam. Early detection can make a significant difference in managing vision problems.
