60% of people spend more than 6 hours a day in front of a digital device*. What about you?

An important and extended exposure to electronic devices (TV, smartphone, tablet) tends to cause short to long-term damages such as glare, digital eyestrain and also sleeping disorders or ocular diseases. For example: blue light was recently identified as being harmful to retinal cells.
