Screen Time and Myopia: What You Need to Know
Why should we be concerned?
Myopia (short-sightedness) is increasing rapidly worldwide. It often begins in childhood and can worsen over time, leading to a higher risk of serious eye diseases later in life, such as retinal detachment, glaucoma, and myopic maculopathy. One important factor behind this rise is lifestyle changes, especially, Increased time spent on screens and reduced time spent outdoors.
What does recent research show?
A large scientific analysis including more than 300,000 children and young people has confirmed a clear link between screen time and myopia risk.
- Each additional hour of screen time per day increases the risk of myopia by about 20%
- The risk starts to rise from as little as 1 hour per day
- It increases more sharply between 1 and 4 hours daily
- Beyond 4 hours, the risk continues to rise, but more gradually
These findings suggest that there may be no completely “safe” level of prolonged daily screen exposure, especially for children.
Why are screens a problem?
Using digital devices (smartphones, tablets, computers, TV) involves:
- Prolonged near vision
- Reduced blinking
- Less time outdoors
Key message
Screen use is now part of daily life, but too much time on screens, especially in children, can significantly increase the risk of myopia. Balancing screen time with outdoor activities is one of the most effective ways to protect your child’s vision for the future.
