Researches Determine that Blue Light Discourages Sleep

Studies have shown for a while that blue light from electronic devices disrupts the body’s natural circadian rhythm and cause sleep disorders and problems.

Researchers from the University of Manchester in England have been studying the spectrum of blue light to determine what specific shade impacts the sleep cycle.

The most recent study determines that cyan blue light, which falls between a green and blue hue, decreases the production of melatonin, the hormone involved in sleep.

Cyan is also used to create other shades, including certain green tones, but researchers determined that the same green colors are easy to duplicate without the use of cyan.

The study was published in “Sleep” and included having people watch a film where the colors included and excluded cyan while measuring the amount of melatonin in the participants’ eyes.

The results of this study are a breakthrough, allowing researchers to know that regulating exposure to cyan can influence how sleepy people feel.

BluTech Lenses are designed to filter cyan hues, which can help people experience a more restful sleep.
