What are the effects of long-term exposure to ultraviolet disinfection lamps? 3 effects to understand
2020-03-25
The main function of ultraviolet disinfection lamp is to disinfect the air. At present, most indoor disinfection in our country will use ultraviolet disinfection lamp or ultraviolet disinfection device. The method is simple and feasible. The wavelength of ultraviolet lamp is 200-270nm, and the wavelength of sterilization center is 253.7nm. It belongs to short wave ultraviolet. This ultraviolet ray mainly kills microorganisms and other pathogens by radiation damage and destroying the nucleic acid function of microorganisms (bacteria, viruses, spores)) to achieve the purpose of disinfection.

So, what are the effects of long-term exposure to ultraviolet disinfection lamps?
1. Pigment deposition
If it is irradiated by ultraviolet disinfection lamp for a long time, it will cause serious skin pigmentation and rough skin. Individual people will also experience skin aging. If the treatment is not timely, it may cause precancerous lesions, such as more common Skin cancer or cataract. Therefore, we must avoid being radiated by ultraviolet light for a long time.
2. Electro-optic ophthalmia
In addition, we must also understand that short-term exposure to ultraviolet disinfection lamps will also have a certain degree of impact on the body, which will lead to electro-optic ophthalmia.

After the emergence of this kind of disease, patients often have symptoms such as red and swollen eyes, dry eyes, and tears. In severe cases, it will cause a certain degree of damage to vision. Under normal circumstances, if the ultraviolet irradiation lamp is irradiated for 30 minutes to 60 minutes, it will lead to the appearance of electro-optic ophthalmia, which is mainly caused by the absorption of a large amount of ultraviolet rays by the cells of our corneal epithelium and the tissue of the conjunctiva.
This kind of disease caused by ultraviolet radiation generally has an incubation period, and it will occur within 6 to 8 hours after irradiation. Therefore, hospital emergency departments often accept such patients in the middle of the night.

3. Damage to the cornea of the eye
Short-term ultraviolet disinfection lamp irradiation, corneal damage is shallow, the main damage to the epithelium, generally 24-48 hours to repair itself. For patients with unbearable pain, doctors usually use chloramphenicol and local anesthetic drops to achieve analgesic and anti-inflammatory effects. At this time, patients and friends must pay more attention to rest, avoid excessive use of eyes, must pay attention to eye hygiene, especially do not easily rub eyes with dirty hands, otherwise it is easy to cause the loss of cornea and prolong the recovery time.
