Everyone was obsessed with the harmful effects of UVA/UVB damage to the skin thanks to more knowledge we currently have about sun exposure and tanning beds. Just like those fads of tanning, technology has become something of a blindly harmful obsession. UVA/UVB light does not hold a candle to what HEV light can do. Researchers are finding that "Blue" or "HEV" (high energy visible) light exposure from television, computer/laptop, tablet screens, and cell phones are harmful to the skin and especially to the human eye. All light is made up of electromagnetic wavelengths. The shorter the wave, the more energy it emits. Blue light has the shortest wavelength of visible light caliber making it damaging to the human body and brain.
HEV light majorly affects the eyes and skin but also has internal body effects such as disrupting circadian rhythm, increasing depression, susceptibility to cancers, headaches, etc.

Eyes
The human eye is sensitive to all visible light. HEV light being the shortest wavelength makes it the most damaging to the retina over time. Unfortunately, with technology, our eyes are pointed straight at it all the time.

Skin
Alike UVA rays that have been shown to cause premature aging in the skin, HEV rays are showing the same, if not, worse effects by causing oxidative stress. Unfortunately, due to the very short wavelength, blue light has the ability to penetrate deeper than UVA and UVB rays. It is said that it can reach the dermis of the skin where our collagen and elastin thrive. This damage may present itself in sagging skin, volume loss, and pigmentation.
