Crizal Prevencia coating can be added to Blue UV capture lenses to “boost” the filtering of blue-violet light by up to 35%. However by adding Crizal Preventia coating, it will cause the Blue UV Captuire lenses to have more annoying blue light reflections off the surface and also cause the lenses to be more yellowish. This defeats the purpose of Essilor Blue UV Capture which is supposed to provide aesthetically transparent lens with low residual tint .

On the other hand, ZEISS BlueGuard is able to provide more blue light protection while maintaining high lens clarity (with less yellowish tint) with less annoying blue reflections. In addition, with ZEISS BlueGuard lenses, ZEISS AntiVirus coating can be added with no extra cost . In our opinion, ZEISS BlueGuard is more superior in blue light protection and offers better value.
