What are the effects of UV sterilization lamps and UV tubes on the human body?

What are the effects of ultraviolet germicidal lamps on the human body? Guangzhou Weigu will take you on a comprehensive journey to find out.

1. Damage to the eyes caused by UV lamps
Improper use of ultraviolet lamps can, in severe cases, cause “photokeratitis.” The main symptoms include eye pain, stinging, and a gritty sensation, as if countless tiny particles were grinding against the eyes. Patients find it difficult to keep their eyes open; when they do open them, tears flow uncontrollably, and they become extremely sensitive to light. Vision may also decline. From a medical perspective, the primary clinical manifestations include redness and swelling of the eyelids, redness of the eyeball, conjunctival congestion and edema, and shedding of squamous epithelial cells from the corneal surface.
2. How to safely protect yourself from UV lamp exposure
Ultraviolet germicidal lamps emit light with wavelengths ranging from 200 nm to 270 nm. The wavelength at which germicidal effectiveness is maximized is 253.7 nm, placing it within the mid-to-short ultraviolet spectrum. Since mid-to-short ultraviolet light cannot pass through ordinary glass, wearing prescription glasses can effectively help protect your eyes from UV damage. Of course, you should still minimize direct exposure of your eyes to ultraviolet light as much as possible.
3. How to Properly Use UV Lamps
When using ultraviolet light for indoor disinfection, be aware that the ultraviolet light emitted has high energy due to its radiation. Therefore, during use, we must avoid direct exposure to the light source. As soon as the lamp is turned on, everyone should immediately leave the area. The recommended disinfection duration is between 30 minutes and one hour. After disinfection is complete, allow the space to air out naturally for at least 30 minutes before re-entering.
4. Remedial Measures in Case of Damage
If your eyes happen to be directly exposed to ultraviolet light, the condition is usually treatable—much like getting accidentally exposed to sunlight. At this moment, it’s recommended to apply an ice pack to help reduce discomfort. Then, put on an eye patch, close your eyes, and take a moment to rest and relax, minimizing eye movements.

The above is a guide on how to protect yourself from UV germicidal lamps. We hope it’s helpful to you.
