Kids and Computer Vision Syndrome

Most of us remember being told not to sit too close to the TV because it would ruin our vision. Well, that may have been an exaggeration of the actual dangers of sitting too near a tube television, but new risks are at play when it comes to electronic screens and the eyes of our children.

Historically, old tube televisions and things like handheld games relied on much different electronics and lights to power their screens. It wasn’t until much more recently that we have moved to bright LED and plasma screens that use a lot of blue light to show unimaginably crisp images. Whereas sitting pretty close to and older style screen twenty years ago probably wasn’t a good idea, it’s likely that prolonged and extreme use of screens nowadays is more problematic.

We know that using a computer can improve school readiness and academic achievement. Children learn digital tools quickly, and have relatively little trouble using them for educational games, math, reading, and more. These devices aid cognitive development when used appropriately, and will not harm your child’s vision. The risks associated with using a digital screen come from prolonged use, improper ergonomics, and developmental problems caused by getting too much screen time instead of getting social interaction and physical activity.

When children use a digital device for long periods of time, they do not “flex” their eyes by focusing on distant objects, as well as looking in the near and intermediate fields. This causes eyestrain. Additionally, sitting for too long and making repetitive movements with hands (like clicking a mouse or controller) or sitting in a position with bad posture or an unsupported upper body can lead to problems like carpal tunnel syndrome and muscle soreness. Everyone knows that kids need time to burn off energy, build gross motor skills, and strengthen their muscles and bones through exercise and play. When they get too much time sitting down while indoors, other important activities like outdoor play, conversation, spacial reasoning, and other skills suffer.

To reduce your child’s risk of computer vision syndrome:

• Limit their time on computers and devices
• Encourage them to take breaks regularly (this is a good habit for many activities)
• Make sure they are sitting in a comfortable, supported position
• Opt for anti-glare protection on their eyewear to reduce eyestrain
• Teach them to view digital screens at arm’s length and not too close
