Ultraviolet disinfection lamp shall be operated carefully to avoid eye injury

This kind of eye disease usually rarely occurs immediately, and the incubation period is 6 8 hours. After the disease, the eyes will suddenly feel burning and sharp pain, accompanied by photophobia, tears, eyelid spasm, headache, flushing and burning of eyelid and facial skin, and conjunctival congestion and edema in the eye fissure. Patients often wake up in the middle of the night with pain, and some sensitive patients even faint with pain.

The radiated ultraviolet energy is large. If effective protective measures are not taken, it is very easy to cause great harm to the human body.

"For example, after the exposed skin is irradiated by this kind of ultraviolet lamp for a certain period of time, the light ones will appear redness, swelling, itching and scaling; the heavy ones will even cause canceration and skin tumors." Experts remind that ultraviolet light is the "invisible killer" of the eyes. If you irradiate the eyes, it will cause conjunctival and corneal inflammation, and long-term irradiation may lead to cataract.

Importantly, UV sterilization is only suitable for clean and flat object surfaces. If you want to disinfect a sofa, dust on the cloth surface may affect the disinfection effect. If you want to disinfect clothes, you should disinfect them one by one, close to each other from the inside to the outside. If there is a position with rough surface or covered by folds, the disinfection effect is not guaranteed.
