Often asked: How Are Infrared Waves Dangerous?

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 the dangers of infrared waves?

Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.

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.

Can infrared light hurt you?

All infrared, visible or ultraviolet electromagnetic radiation can cause injury to the eye in sufficient concentrations, but this is very rare. The infrared light needs to be extremely intense to cause harm. Infrared lamps and incandescent bulbs are not powerful enough to cause such harm.

How does infrared waves affect Earth?

Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface, thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation.

Which is more harmful ultraviolet or infrared?

When you look at the EM spectrum, UV waves are quite a bit smaller in wavelength than infrared, and x-rays/gamma rays are even smaller. Therefore, UV waves are probably causing more harm than infrared waves, and x-rays/gamma rays are probably doing even more damage.

How are IR rays harmful to the atmosphere?

The earth’s surface and the clouds above it absorb radiation from the sun’s rays and re-emit it as infrared radiation back out into the atmosphere. The trapped radiation causes increased temperatures and changes in weather that could be harmful to people and animals.

Is infrared light safe for humans?

Infrared light is delivered to the site of injury or inflammation at certain wavelengths, promoting cell repair. The key characteristic of infrared light is its ability to penetrate even the deep layers of the skin, providing better pain relief. Also, infrared light is safe, natural, non-invasive, and painless.

Are infrared microwaves and radio waves harmful to us?

Over-exposure to certain types of electromagnetic radiation can be harmful. The higher the frequency of the radiation, the more damage it is likely to cause to the body: infrared radiation is felt as heat and causes skin to burn.

Does infrared have radiation?

Infrared radiation (IR), or infrared light, is a type of radiant energy that’s invisible to human eyes but that we can feel as heat. IR is a type of electromagnetic radiation, a continuum of frequencies produced when atoms absorb and then release energy.

Is infrared LED harmful to eyes?

Infrared, visible or ultraviolet electromagnetic radiation, in sufficient concentrations, can cause damage to the human eye. To date, Light-emitting Diodes (LEDs) have not been found to cause any damage. The human eye can withstand only a finite amount of optical radiation, beyond which it can be irreversibly damaged.

Why can’t human eyes see infrared light?

The human eye can detect the visible spectrum of the electromagnetic spectrum — a range of wavelengths between 390 to 700 nanometers. Because infrared light has less energy than the colors we see in the visible spectrum, it can’t activate photoreceptors in the eye.

Is infrared camera safe?

Most important to know, for those who are worried about safety, is that infrared cameras, like any other cameras, capture energy emitted from the body and do not generate any radiation themselves. So there is no risk from them.
