Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging.

What are dangers of infrared waves?
IR raises the internal temperature of the eye, virtually “baking” it. Prolonged IR exposure can lead cataracts, corneal ulcers, and retinal burns. Don’t stare at the sun! The infrared radiation in the sunlight damages skin.
What are the uses and dangers of infrared waves?
Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark. The heating effect of IR can cause burns to the skin.
What are the health effects of infrared?
Infrared therapy has many roles in the human body. These include detoxification, pain relief, reduction of muscle tension, relaxation, improved circulation, weight loss, skin purification, lowered side effects of diabetes, boosting of the immune system and lowering of blood pressure.
What are the effects of infrared waves on the human skin?
Recent work demonstrates that IR and heat exposure each induces cutaneous angiogenesis and inflammatory cellular infiltration, disrupts the dermal extracellular matrix by inducing matrix metalloproteinases, and alters dermal structural proteins, thereby adding to premature skin aging.
Is infrared light harmful to skin?
Intense infrared radiation, or heat, has been shown to be detrimental to the skin. Heat increases the production of melanocyte pigment within the skin, so it can worsen melasma and other skin pigmentation concerns.
What are the disadvantages of visible light?
Disadvantages: They can cause sunburn or even skin cancer if used in large quantities. Visible Light: Visible light is the part of the spectrum you can see. Each different wavelength of light has a different color. Disadvantages: If there is too much exposure to visible light, it may cause blindness or eye damage.
What is infrared and its effect?
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. The balance between absorbed and emitted infrared radiation has an important effect on Earth’s climate.
What does infrared radiation do?
Infrared sensing One of the most useful applications of the IR spectrum is in sensing and detection. All objects on Earth emit IR radiation in the form of heat. This can be detected by electronic sensors, such as those used in night vision goggles and infrared cameras.
Is infrared is safe?
Are Infrared rays safe for people? Far infrared heating is 100% safe and natural for our bodies, and our well-being, as the human body is designed to accept and emit infrared. The feeling of warmth from infrared is particularly comfortable. It is UV that is harmful, not infrared, and so there is no need to worry.
Can infrared also harm the skin like the UV rays?
” Visible and infrared on their own have a small effect on skin damage but their potency is increased dramatically when UV is present.” In contrast, cells from the dermal layer deeper in the skin (fibroblasts) were damaged by UV as expected, but had greater damage from the complete solar light.
