Ultraviolet light is basically a type of electromagnetic radiation found in sunrays, which was discovered by German physicist named Ritter in 1801. Besides, there are different types of ultraviolet rays of various wavelengths such as UV-A, UV-B and UV-C.

These rays are the rays coming to the earth surface together with the sunrays. Especially, UV-A and UV-B are the type of ultraviolet rays that most frequently affect earth surface. On the other hand, UV-C rays are completely held in the ozone layer for that reason, it cannot able to reach the earth surface. Actually, UV-C rays are the most affective form on bacteria, viruse, fungi and its spore. At the mean time, several studies have been conducted in this field over the years and its reliability has been proven. UV-C rays are the well accepted way by studies that is actively used in the treatment of some diseases such as neonatal jaundice, vitiligo, blood sterilization, hepatitis infection and so on. Different wavelengths of UV-C rays are used in each of these diseases and sterilization methods. Actually, the main point here is that appropriate level of wavelength of UV-C rays will be effective for medical application and will not harm human health.

UV-C Rays completely destroy all Viruse including COVID-19, Bacteria, Fungi, Mold and Microbe while it deteriorates dna and rna structure of them. It has been used most widely in the world and has been proven by clinical trials.
