LUMALENS PH (Photochromic) J.Red ION
15%-58% (automatically adjusts according to UV intensity)
A versatile lens color suitable for use from nighttime to sunny days. Based on a very light blue tint, it adjusts to the intensity of ultraviolet light. Recommended for those seeking a bright and natural tone.
PHOTOCHROMIC (photochromic/light-adjusting) technology changes the brightness of the lens in response to the amount of ultraviolet (UV) light. The lens darkens in sunny conditions with high UV levels and brightens in bad weather with low UV levels.
This photochromic function has been added to the conventional JAPAN LUMALENS, which are specially adjusted to suit the eyes of Asian people and Japan's climate with its frequent bad weather. This has successfully enabled them to handle a wider range of weather and time periods, from strong sunlight that was previously not fully covered to low-light conditions at night.
