UV also carries a risk of eye damage.
UV-A can cause damage to the lens, possibly leading to cataracts.
This damage is cumulative — the lens, once damaged, does not “grow back.” UV-B can damage the retina and cornea but we don’t have to worry about UV-B from those case lights.18 Apr 2005
Are UV lights harmful to humans?
The UV spectrum thus has effects both beneficial and harmful to human health. The lower wavelength limit of human vision is conventionally taken as 400 nm, so ultraviolet rays are invisible to humans, although some people can perceive light at slightly shorter wavelengths than this (see below).
Are UV light bulbs safe?
Hazard and Risks from UV Lamps
UV lamps produce light radiation from ultraviolet through visible to infrared radiation. The biggest hazard comes from the UVR. UVR cannot be seen and is not felt immediately, but it is harmful to both the eyes and skin.
Can UV light bulb damage eyes?
UV rays may lead to macular degeneration, a leading cause of vision loss for older Americans. UV rays, especially UV-B rays, may also cause some kinds of cataracts. A cataract is a clouding of the eye’s natural lens, the part of the eye that focuses the light we see.
How can UV rays be harmful?
UV exposure is a powerful attack on the skin, creating damage that can range from premature wrinkles to dangerous skin cancer. Damage from UV exposure is cumulative and increases your skin cancer risk over time. While your body can repair some of the DNA damage in skin cells, it can’t repair all of it.
