UVC LED, the main body of ultraviolet radiation on human body is the eyes and bare skin. Short term high-intensity irradiation can burn the eyes and skin. Severe long-term high-intensity irradiation can even cause skin cancer.
UVC LED ultraviolet ray penetrability is very weak, ordinary transparent glass, clothes, plastic, dust and so on can be completely blocked. Therefore, wearing glasses, such as without glasses, avoiding eyes looking at ultraviolet lamp, and covering the bare skin as much as possible, can protect eyes and skin from UVC ultraviolet damage.
Ultraviolet radiation in a short time is just like burning in the scorching sun. It is no harm to human body, but it is beneficial. UVB LED ultraviolet rays can promote mineral metabolism and vitamin D formation in vivo.
To prevent UVC LED UV damage principle: 1) glasses (glass or resin lenses can be); 2) to avoid the eyes of ultraviolet lamp; 3) wear long sleeved clothes, covered hands and other exposed skin; 4) with things around UV blocking, such as walls, furniture, curtains, books and newspapers; 5) to avoid long time irradiation of ultraviolet radiation on human harm, not a short time.
