We use a cellulose acetate lens to help with anti scratch and UV protection which is produced in Italy.
Ultraviolet A (UVA) is made up of wavelengths 320 to 400 nanometers (nm) in length.
Ultraviolet B (UVB) wavelengths are 280 to 320 nm.
Ultraviolet C (UVC) wavelengths are 100 to 280 nm.
Only UVA and UVB ultraviolet rays reach the earth's surface. The earth's atmosphere absorbs UVC wavelengths.
Our lens check has filtered in the 300-380 range. So it blocks out most of UVA and UVB wavelengths. UVC wavelengths are 100% blocked out.
