I remember being told by my parents that if I sat too close to the television, I would ruin my eyesight (not exactly true). I also remember having a television with only seven channels, so while I did watch a lot of television, it was still a limited viewing experience. While the same holds true that computer screens won’t damage our eyes, there are some differences we should consider, including the fact that digital devices demand near-vision viewing.


With today’s generation having access to any program at any time, a screen usually within arm’s reach at any time, and the ability to view multiple screens at the same time, it may be worth taking a closer look at the dangers of being too close to the screen for too long.

Extended screen time in front of a glowing monitor makes us blink less than we would if we were performing another near-vision task, such as reading a magazine or writing a letter, and that results in eye strain or fatigue. Symptoms of eye fatigue include sore, tired, burning or itchy eyes; watery or dry eyes; and blurred or double vision. Physical symptoms include headache, sore neck and sensitivity to light.

It makes sense that adults who spend their days in front of a computer (guilty!) are more prone to experiencing these symptoms. But, children today also spend a lot of time in front of a screen. Schools are increasingly using technology in the classroom, and after-school hours are spent playing computer games, using social media, texting, and yes, watching television. A recent report from The Vision Council found 64% of children and teens spend more than five hours a day looking at digital screens.

In addition to eye strain, the blue light that devices emit can disrupt sleep and has been linked to retinal damage, including age-related macular degeneration and cataracts. If links are found in adults, you have to wonder what damage will occur over the long term in this generation of eyes.
