SAFER CONTRAST 589, THE TRASPARENT LENS THAT BLOCKS THE NIGHT AND DAY BLIND AND PROTECTS LIKE A SUNGLASSES.

SAFER CONTRAST 589 has been designed to block the night and day blind (day blind: in equal measure obtained with normal sunglasses).

The lens has a double function because it protects our eyes from the visible high-energy blue light (HEV) with a shield at 420nm and makes a selective cut at 589 nm reducing the impact of light on the most dazzling wavelength for human.

Safer contrast reduces the light at 589 nm and provides
