UV Light Isolation Filters

Ultraviolet light refers to the light with a wavelength of 10 nanometers to 400 nanometers (nm) in sunlight, which can be divided into UVA (ultraviolet light A, wavelength 320~400 nanometers, long wave), UVB (wavelength 280~320 nanometers, medium wave), and UVC (wavelength 100~280 nanometers, short wave). UVA is the most carcinogenic, and the sunburn and sunburn effects are 1000 times that of UVB. UVC can be blocked by the ozone layer. IR (Infrared) is infrared light, which can cause sunburn, microvascular dilation, dermatitis, and promote the carcinogenicity of ultraviolet light. Ultraviolet light exposure will cause the skin to produce a large number of free radicals, leading to peroxidation of cell membranes, causing melanocytes to produce more melanin, and distributing it upward to the epidermal stratum corneum, causing black spots. Ultraviolet light can be said to be the biggest culprit for skin wrinkles, aging, sagging and dark spots.

To isolate ultraviolet light, you can choose the LP-430nm long-wave filter, which can control the light in the ultraviolet band to OD3, and the average transmittance is only 0.01%. Then the visible light band can pass normally without affecting normal vision.
