Computer, phone, tablet screens may be keeping you awake

It might seem innocuous, but the glare from the computer screen or cellphone might be getting between people and a good night’s sleep.

While there are many ways to adjust the blue light, the culprit of the problem, one easy fix is f.lux, which adjusts the color on people’s computer screens depending on the time of day.

People can download the app on their computers or mobile devices and adjust preferences to sleep schedule. The program is available for Apple, Windows and Linux.

At night, the screen changes color to reduce the blue light.

Blue light is made up of electromagnetic particles that are emitted from computer and tablet screens and phone displays.

According to The Vision Council, blue light has been linked to numerous health issues such as age-related macular degeneration and cataracts. At night, it can also be the force that keeps people awake.

The Vision Council recommends using light-blocking materials such as blue attenuating anti-reflective lenses or specialty filters.
