3.What is UV400?

UV 400 means that the lenses will block Ultraviolet (UV) waves shorter than or equal to 400 nano-meters (nm). All UV waves come in different lengths as shown in the chart below.

UVA: 320-400 (nm)

UVB: 290-320 (nm)

UVC: 200-290 (nm)

Since all of these UV rays are shorter than or equal to 400 nm, they are blocked by the lenses - keeping your eyes safely protected.

This also explains why you can still see color. The color red has a wavelength of 680 nm. Since it is greater than 400 nm, it is not blocked by the UV 400 lenses.
