Pitcha SPACE-R - lenses with self-tinting lenses instantly adapt to the current light conditions, the lenses darken in the sun and lighten immediately when entering the shade. The lenses react to the intensity of UV radiation. They either brighten or darken accordingly. From the point of view of versatility of use, photochromic lenses seem to be ideal. Currently, these lenses are the absolute top of the market.
The NTS(non temperature sensitive) technology activates the tint of the lenses according to the intensity of UV radiation, not according to the ambient temperature.
Photochromic lenses are more durable, lighter than polycarbonate lenses, and are photochromic for life.
