Also referred to as blue light, HEV (High Energy Visible Light) is equally harmful as UVA/UVB rays. Just like UVA/UVB rays, HEV light also steals away your youthful and healthy skin. The visible effect of HEV light has been discovered recently. HEV light is responsible for causing premature aging. It is a high-frequency light which is visible to us in a blue band and ranges approximately from 380 to 500 nanometers. Even reflective surfaces like water glass, snow, sand etc e forms of HEV light. This light is emitted from your electronic gadgets without which you cannot even imagine your life anymore like mobile phones, laptops, computers, tablets etc.
HEV light damage your skin but it differs from UVA and UVB rays. While UVB light causes sunburn and its wavelength varies between 280nm to 320nm, UVA light cause deeper damage and its wavelength ranges from 320 nm to 400 nm. Studies have reported that the damage caused by HEV light is equal to the damage caused by UVA and UVB light together. Blue light is even more harmful. The reason behind the sky being blue even after sunset is the presence of blue light. This means that blue light not only harms your skin deeper than UVA or UVB rays but it is also present in the night and is, therefore, HEV damages skin 24x7.
