The Chinese government recently implemented a new policy that’s sparked conversations about childhood myopia and online gaming.
Under the policy, Chinese children and teens under the age of 18 are only permitted to play online video games for one hour on weekend evenings and public holidays — a significant reduction compared to their previous online gaming allotment. This restriction includes all forms of video games, from handheld devices to computer and smartphone gaming.
The government hopes to combat a common condition called online gaming disorder, or video game addiction, which affects more than 30% of children in China. Another potential benefit of limiting online gaming may be a reduction in childhood myopia progression, something we explore below.
The Link Between Online Gaming and Myopia Progression
Myopia, or nearsightedness, is a condition that causes blurred distance vision. Several factors contribute to the onset and progression of myopia, including genetic and environmental.
Several studies have found that screen time, along with other forms of near work, is associated with higher levels of myopia and myopia progression in children.
According to a study published in the British Journal of Ophthalmology (2019), children who engage in screen time for more than 3 hours per day have almost 4 times the risk of becoming myopic. Younger children, around ages 6-7, are even more susceptible to experiencing screen-related nearsightedness, with 5 times the risk compared to children who don’t use digital screens.
Limiting screen time may also encourage children to spend more time outdoors in the sun, a protective factor against developing myopia and slowing its progression.
In The Sydney Adolescent Vascular and Eye Study (2013), researchers found that spending at least 21 hours outdoors per week was more important for delaying the onset of myopia than limiting near work in both younger and older children, although both were effective.
What’s the Bottom Line?
Although online gaming can give children a sense of community and togetherness, excessive online gaming can increase a child’s risk of developing myopia and contribute to its progression.
The good news is that parents can make eye-healthy choices for their children that can have lifelong benefits. Limiting near work activities like online gaming and other screen time, and encouraging your children to play outdoors can significantly reduce their chances of developing high (severe) myopia.
How Myopia Management Can Help
The best thing that parents can offer their children to prevent myopia and halt its progression is a custom-made myopia management treatment plan with an eye doctor.
Whether or not myopia has set in already, we can help preserve your child’s eye health and lower their risk of developing sight-threatening eye diseases like glaucoma, cataracts, macular degeneration and retinal detachment in the future.
