Anti-UV and anti-glare RayBlocker coating: The lenses include the RayBlocker-HD Optical MultiCoat Technology that filters the light wave length to the 400-600nm range and makes for the most comfortable viewing. The RayBlocker-HD lenses absorb ultraviolet (UV) radiation that has been linked to cataract formation and also absorb much of the blue light spectrum (also known as blue blocking) to provide a more soothing, comfortable viewing experience. The glare relief function of the RayBlocker-HD is achieved by filtering the shorter wavelengths of the visible spectrum, which scatter within the eye causing glare. Reducing the shorter wavelengths also provides the benefit of highlighting visual distinction and enhancing contrast.

What you see is not what they see: The Optical Multicoat RayBlocker technology causes an unexpected effect that the view from the 'outside looking in' is very different from the 'inside looking out'. Compare the actual Dive Gear Express test photographs at right. From the point of view of others looking at the mask on the diver, they will see a color that shifts across the red/orange/yellow portions of the spectrum depending on the viewing angle. However, looking from the divers point of view, the lens is clear.
