Dangers of Overexposure to ultraviolet, infrared and high-energy visible light. This article discusses the exposure hazards to eyes/face associated with specific non-ionizing electromagnetic radiation (EMR) not addressed by OSHA: ultraviolet (UV), infrared (IR) and high-energy visible light (HEV).
In this way, is Visible Light harmful or helpful or both?
Visible light waves also make our TV, computer and cell phone screens work. Visible light is typically pretty harmless. However, some light can be so intense that it can damage the receptor cells in your eye causing temporary or permanent blindness. High powered lasers can also be damaging and will cause burns.
What are the effects of visible light on humans?
Effects of Visible Light on the Skin. Electromagnetic radiation has vast and diverse effects on human skin. Although photobiologic studies of sunlight date back to Sir Isaac Newton in 1671, most available studies focus on the UV radiation part of the spectrum.
Why does exposure to visible light not damage skin?
UV waves are shorter than visible light waves, so UV possesses more energy than regular light. UV photons have the right energies to cause chemical changes. When UV light hits your skin, the DNA in your skin cells can undergo chemical change. By comparison, visible light has wavelengths from about 400 to 700 nm.
