We didn’t invent blue light when we made digital devices, including computers, tablets, and phones. High energy wave lengths like blue light are literally what makes the sky look blue!
Today, however, we encounter blue light everywhere. Whether we are using computers or working and living under LED lights, we are surrounded by blue light all day long.
Blue light is even beneficial, regulating our circadian rhythm and boosting our alertness, but just like regular sunlight, we can have too much of a good thing.
Our eyes are not very good at blocking blue light. By experiencing blue light all day long, especially as it comes from our digital devices right into our eyes, this high energy light can contribute to eye strain and eye damage, like macular degeneration, which can lead to permanent vision loss.
Working and playing with digital devices before bedtime can reduce the quality of your sleep. Remember, your body interprets blue light as a signal to be awake and alert!

There’s no reason to panic, but it is a good idea to be aware of how blue light can affect your eye health and to limit your exposure. You don’t have to give up your digital devices, but you might check their settings and moderate their use.
As manufacturers learn more about the dangers of blue light, new computers, tablets, and phones are sure to have new blue light settings, and of course your optometrist can recommend lenses and filters that protect your eyes from blue light.
