An improved ten-layer performance polarized lens for sunglasses. The lens design
maximizes visual acuity while minimizing blue-light transmission using a multi-layer
dielectric mirror to reduces glare and overall light transmission, two layers of
high-contrast blue-blocking amber CR-39 plastic or polycarbonate, sandwiching a
polarizing layer. An outer hydrophobic overcoat is also provided to protect against
haze, delamination, and smudging, The foregoing layers are arranged to provide
a balanced light transmission profile optimum for use on the water in which 100%
of UV-A & B light is absorbed to at least 400 nm. The resulting dielectric-mirrored
sunglass lens reduces both overall light transmission and ocular photochemical damage.
