UV420 Technology

The UV420 filter blocks wavelengths between 380 and 420 nanometers, corresponding to the most energetic and potentially harmful portion of visible blue light. This selective filtering preserves color perception and avoids the yellowish tint characteristic of lower-quality filters.

SWISSLENS® technology eliminates the unpleasant yellow tint of early generations of blue light blocking lenses, providing a neutral base and natural aesthetic.
