ジョイカジノ 系列erials
ジョイカジノ 系列erials are mainly used for eyeglass lenses, including lenses for regular eyeglasses as well as sunglasses. Lenses made with ジョイカジノ 系列erials are ideal for both indoor and outdoor use. When exposed to the strong ultraviolet rays of outdoor sunshine, photochromic lenses turn to gray or brown to protect the wearer from glare and ultraviolet light, and return transparent indoors.
Tokuyama is actively involved in the development of dyes. The company offers a variety of colors, allowing lenses to go from transparent to gray, brown, blue, and pink. We have also achieved the world’s highest level of quality in terms of performance, including in color density and durability. We will continue to use our advanced technological abilities to develop products that meet the needs of our customers.
