The Effects of Blue Light

Today people are in front of screens more than ever. The amount of time people spend using digital devices, and how close their eyes are to the screens can increase their risk of damage to their eyes.

The eyes are great at blocking UV rays from reaching the retina at the back of the eyeball. When it comes to blocking blue light the eyes aren't as effective. Almost all passing blue light passes through the lens and cornea and reaches the retina.

An over-exposure to blue light can damage light-sensitive cells in the retina. This can increase the chances of macular degeneration which is the leading cause of vision loss amongst American adults. The increased exposure to blue light from digital devices can increase peoples risk of macular degeneration later in their lives.

The exposure to blue light can decrease contrast which can lead to digital eyestrain. The symptoms of digital eyestrain can lead to sore eyes, headaches, and a disruption to your sleeping patterns.
