As screens have come to monopolize the vast majority of our time day to day, there has been an increased focus and consideration placed on the impact that screen time has on children. While some studies and opinions may differ on the pros and cons, we do know that more screen time increases the chance of vision related problems.
Impacts of screen time on eyesight
Myopia- a rise in nearsightedness (myopia) is a global concern with more cases in adults and children than ever before. Per a 2017 study, nearly 42% of people in the United States are nearsighted. There has also been a noticeable trend of kids developing myopia at younger ages. The connection between myopia and screens is more screen time causes a decrease in children using their distance vision and requires them to spend much more time using their near vision.
Dry eye syndrome- eyes dry out and may burn, sting and turn red. When looking at a screen, kids blink less often and their tear ducts might not produce enough moisture to keep eyes from becoming dry.
Computer vision syndrome or digital eye strain- children can develop difficulties shifting their eyes from near to far, and experience headaches, blurred vision or dry eyes. These are all symptoms of computer vision syndrome which results from excessive screen time.
So, what can be done?
While many of the same remedies for eye issues relating to screen time apply to kids as well as adults, the best solution for children is to reduce their screentime and encourage other forms of play. It is especially important for children to get outside where they can utilize both their near and distance vision, get a break from blue lights and work on motor skills and hand-eye coordination.
For children ages 2-5, try to limit screen time to only 1 hour per day. For older children, enforce one hour of screen-free time before bed.
Remember the 20 - 20 - 20 rule: Every 20 minutes, take a 20 second break and look at something 20 feet away.
If you have any questions or concerns about your child's vision or eye health, be sure to speak to your optometrist or pediatrician.
