Ultraviolet (UV) is a type of electromagnetic radiation with wavelengths ranging from 10nm-400nm. We interact with UV light daily given that it makes up 10% of the sun’s total radiation. UV is widely known for its fluorescing properties for glow in the dark products and apparel, but its application reaches far beyond that.
As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200 nm to 300 nm it is absorbed by DNA, RNA, and proteins. Absorption by proteins can lead to rupture of cell walls and death of the organism.
Darker sunglasses decrease the amount of visible light that passes through the lenses compared with lighter lens tints, but they don't necessarily provide greater protection from invisible UV rays. For adequate sun protection, make sure your sunglasses block 100 percent UV, regardless of the color or darkness of the lenses.
74-UV material: Dynasil 1100 quartz (200 nm - 2 µm*) 74-VIS material: BK 7 glass (360 nm - 2 µm*) Lens barrel: stainless steel with black oxide finish Threads: UNC 3/8-24 * Though the product can be used to 2 µm, it can be configured to "see" only to 1100 nm with our S2000 spectrometer.-1-
Collectively, our studies suggest that far-UVC light (200–225 nm), unlike conventional UV germicidal lamps, has considerable promise to be a safe and inexpensive modality for SSI reduction, while being cytotoxic to both drug-resistant and drug-sensitive microbes (22).
