This light could be driven from sunlight, and the sun is the main resource of it, however, our daily exposure to various screens and indoor lighting can increase absorption of this harmful light. Several studies examined the effects of blue light on the skin and resulted that it can manipulate the natural function of the skin and could deliver harmful impacts on our skin. Blue light is also known as High Energy Visible (HNV) that does not come only from sun exposure but also from computer monitors, cell phones, tablets, and other digital devices.

There are no clear statistics about how much of our time would be consumed staring at screens, but according to some studies, we spend about 50 percent of our lives staring at screens. It is already known that this can be dangerous for eye health and could contribute an important role in various diseases related to the eyes. It should be noted that blue light is not a bad thing by itself, and it helps our body to have a regulated natural sleep-wake cycle.

How blue light damages?

 

Today it is accepted by dermatologists that blue light triggers certain skin diseases like melasma, in which the skin is stimulated to produce more pigment. Other evidence shows that as blue light absorbs the skin, skin generates reactive oxygen species that lead to DNA damage, thus it can cause inflammation and low production of healthy collagen and elastin.

As we mentioned earlier, this topic is fairly new, and few studies are done to understand its different aspects. It is known that blue light can cause damage to the skin, but it is not clearly understood how digital devices deliver these damages. At this time, there is no truly understood threshold for when time spent on screens starts to damage the skin. Depending on the screen device that is used, a wide range of estimations is available.

They think computer screens are not worrisome because people sit farther away from them.
