It’s alarming that, since 2007, new screens emit an average 5 times more high energy visible light (HEV) than previous technologies. The American Optometric Association named Computer Vision Syndrome (CVS), or Digital Eye Strain, the group of eye and vision-related problems that result from prolonged computer, tablet and cell phone use. Up to 80% of screens users report suffering from these symptoms.
Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods, even after stopping work at a computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen with future digital screen use.
Numerous studies, such as the ones led by Harvard Medical School, link the emission of blue light to decreases in melatonin levels. This hormone regulates the circadian rhythm (our biological clock), that’s why more exposure to high energy light can affect our sleep negatively.
Worse, the studies have linked working late at night and direct over-exposure to high energy visible light can lead to certain types of diseases: breast and prostate cancer, diabetes, heart disease and obesity.
You are not aware of it, bu tour eyes are exposed to permanent damage and other symptoms that can mean serious consequences.
