Is Sitting Too Close to the TV Really Bad for Your Eyes?

too close to the tvIf you grew up with a television in your house, how many times did you get scolded for sitting too close? In the Western world, there probably isn’t a single kid who wasn't told that sitting too close to the TV is bad for their eyes. But is that true? Could it be possible that countless kids heard this warning without warrant?

It turns out, that no, sitting too close to the TV does not impair one's vision. In fact, kids (and grown ups) who do this are probably doing so because they are nearsighted and need a pair of glasses, already.

However, the real danger when it comes to TV and digital screens, is blue light. Blue light, found in the spectrum of visible light, has very high energy (but short) wavelengths. Hence, blue light is also called high-energy visible (HEV) light. It should be noted that blue light is not always bad, but when your eyes are exposed to excessive amounts, thanks to extended time watching TV and/or looking at a digital screen (i.e., your smartphone, your computer screen, etc.), you increase the chances of permanently damaging your eye leading to eye diseases like macular degeneration. Blue light and LEDs are also known to disturb sleep patterns since it suppresses the stimulation of your body to produce the sleep hormone, melatonin.

Thus, if you or your child is on a digital screen for long over 2 hours a day, and you are not sure if the screen comes with a blue light filter, consider investing in filters that you can put on them that do. And if you wear glasses, it's worth the extra investment to get lenses that block blue light. Computer glasses also come available for people who do not need prescription lenses. Note that not all anti-reflection glasses block blue light.
