The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface.

If UV lamps are used in hospitals and kitchens, they're certainly safe enough to use in the home. UV lamps, even though they use ultraviolet light, don't directly affect you. The lamp only affects whatever is directly in its line of sight. However, it is worth noting that UV lamps can impact the actual HVAC system.

While Corn Snakes don't need UVB to survive, UVA/UVB light has been shown to greatly improve the immune system, health, and wellness of all reptiles, both diurnal and crepuscular. Make sure to place the light over the side with the heat mat to help create that warm side of the thermal gradient.

UVA rays can penetrate your skin more deeply and cause your skin cells to age prematurely. About 95 percent of the UV rays that reach the ground are UVA rays. The other 5 percent of UV rays are UVB. They have higher energy levels than UVA rays, and typically damage the outermost layers of your skin, causing sunburn.

Well, UVB can harm your plants, just like it can humans. Unfortunately, we can't give our plants sunglasses or sun block, but Mother Nature has an answer. ... There is more UVB the higher up you go, so plants that grow there will naturally have more trichomes and higher potency.

UVB light allows the synthesis of vitamin D3, which helps to absorb calcium. UVC light is not required for reptiles, but it can help kill bacteria. It's important to note that at high levels of exposure this light can be harmful to most animals. ... Over time UV output will diminish.

UVA rays can penetrate your skin more deeply and cause your skin cells to age prematurely. ... The other 5 percent of UV rays are UVB. They have higher energy levels than UVA rays, and typically damage the outermost layers of your skin, causing sunburn. These rays directly damage DNA and are the cause of most skin cancers.

UVB light has a much smaller range than UVA with a wavelength of 290 nm to 320 nm. Although it's not as deeply skin-penetrating or omnipotent as UVA rays, UVB light is very powerful, that's why it's directly responsible for sunburn and other visible discolorations to skin's surface.
