Due to the global outbreak of coronavirus disease (COVID-19) caused by the novel coronavirus SARS-CoV-2, various sanitation strategies have been adopted worldwide so that the spread of the virus and the disease can be prevented.
One such strategy which is adopted for sterilization in offices and homes is the use of consumer-grade UV lamps or the germicidal lamps. The light from the germicidal lamps is radiant energy which can inactivate microbes such as bacteria, viruses, mold and fungi. But, while the UV light from these germicidal lamps might kill the viruses and bacteria, it’s improper use can be harmful and dangerous.
During the height of the pandemic, there was a significant increase in the number of patients with irritation and painful inflammation in the cornea of their eyes known as photokeratitis. This happens due to direct exposure to the germicidal lamps which emit UV light within the C range to kill bacteria and viruses. Due to overexposure to UV rays for a few hours, patients experienced burning and intense sensitivity in their eyes. It’s quite painful but with prompt use of eye drops for lubrication and use of antibiotics for preventing the infection patients recover and do very well.
Moreover, some UV-C emitting germicidal lamps are proven to be effective in killing various microbes and viruses but till date, there’s no evidence that they’re effective specifically against the COVID-19.
Thus, before using these germicidal lamps one needs to be fully aware of their proper usage and also pay close attention to the recommendations by the manufacturer to prevent eyes and skin damage or any kind of injury.
