4 The hazards of UV disinfection lamps
Ultraviolet light has a strong killing power on bacteria, the human body also has a certain degree of harm, the human body is the most vulnerable part of the cornea of the eye, so at no time should not use the eyes directly on the lit lamp to avoid injury, in case you have to look, the application of ordinary glass (wearing glasses) or light-transmitting plastic sheet, as a protective mask. Never use quartz glass by mistake, because ordinary glass is almost completely impervious to ultraviolet light. Once injured, there is no need to panic, facial burns, a few days after the epidermis off, without medicine and healing. Eye injuries will be red, swollen, tearing, stinging, about three or four days to heal. In any case, it is still recommended to go to a doctor as soon as you encounter an injury.
(A) Injuries to the skin
1, leading to skin allergies: If the exposed skin is exposed to this type of UV radiation, it will damage the skin and cause redness, swelling, flaking, itching, pain, rashes, and other allergic symptoms.
2, lead to skin aging: skin is strong UV radiation, will appear aging, this is because UV radiation will cause the skin tension becomes poor, elasticity dissipation and sagging and another aging phenomenon. UVR will also destroy the collagen fibers in the skin tissue, making the skin appear wrinkles, a sagging phenomenon.
3, leading to skin tumors: UV disinfection lamp irradiation of strong ultraviolet radiation may lead to skin tumors, UV may affect the body’s regulatory immune response and induce skin cancer, resulting in melanoma, skin cancer, etc.
(B) The damage to the eyes
1, caused by electrophotographic ophthalmia: UV disinfection lamp damage to the cornea and conjunctival epithelium caused by inflammation, can also be called electrophotographic ophthalmia. Characterized by redness and swelling of the eyelids, conjunctival congestion, and edema, intense foreign body sensation and pain, symptoms include fear of light, tearing and inability to open the eyes and blurred vision during the onset.
2、Causing inflammation of conjunctiva: The damage to strong ultraviolet light to the cornea is huge, which can easily cause pain in the eyes and lead to inflammation of the cornea and conjunctiva.
3、Produce cataract: Strong UV rays cause the lens to become opaque, thus causing cataracts to occur.
4, lead to retinal lesions: strong UV light can easily cause retinal lesions, UV light containing UVA can penetrate deeply into the eye, directly to the deep part of the eye and cause retinal lesions.
