Lenses that can be used as both regular glasses and sunglasses in one pair of glasses!
We offer "photochromic lenses" that change color in intensity depending on the amount of ultraviolet light. In bright outdoor sunlight, they reduce glare as sunglasses, while indoors they ensure a bright field of vision. 【Features】 ■ We possess two types of photochromic processing technologies: Top Spin Coat and In-Mass. ■ Top Spin Coat can be applied to a wide range of substrates with an INDEX of 1.50 to 1.76. ■ In-Mass SF allows for a photochromic coating layer of approximately 0.8mm on the surface. ■ Contract coating processing is available. *Coating on UV420 substrates is also possible from substrate supply. ■ We also have photochromic coating materials that develop color in the visible light range. ■ Cuts blue light by 30%. *For more details, please download the PDF or contact us.
