Did you know that blue light emitted from digital devices can be harmful to your eyes?
What is blue light?

It’s a type of light that gives off a blue color. Outdoor exposure comes from the sun. Indoor exposure comes from artificial sources of blue light, such as computers, tablets, cell phones, and televisions.

Why is it dangerous?

Blue light is harmful because it’s the highest energy wavelength of visible light, able to penetrate all the way to the back of the eye. Although blue light is nothing new, the issue for concern is the amount of blue light exposure that we get each day through technology use. Over time, blue light can impair visual daily performance, disrupt our ability to sleep, and contribute to the development of macular degeneration.

How to protect your eyes.

Try to limit your digital device use, especially before bed. Secondly, see your Eye Consultants of Atlanta physician about BluTech lenses that filter out blue light. Now available at our Optical Centers, these lenses can help minimize the direct blue light exposure you get throughout the day.
