BLUBLOCK is the new coating from IRIDIUM that filters out BLUE LIGHT, light rays with a wavelength between 380 and 500nm. The main natural source of these rays is the sun but they are also present in artificial light, particularly that emitted by the screens of such modern devices as TVs, computers, tablets and smartphones.
The design is optimized computationally using our lens design system SimPAL for a dense grid of setting combinations.
