Tac lens can effectively reduce glare, eliminate dazzling reflected light and scattered light, turn messy light into parallel light and make things clearer and softer.
The polarization angle and radian of tac lens are professionally designed and processed, so the wearer will not feel distorted and dizzy.
Tac lens consists of seven layers of materials. The first layer is the polarizing layer, which is the core of the lens, providing more than 99% polarizing effect and effectively absorbing glare. The second and third layers are adhesive layers, which can effectively resist cutting, baking, bending and cutting and stand the test of harsh environment. The fourth and fifth layers are ultraviolet absorption layers, which can absorb more than 99% ultraviolet rays. The sixth and seventh layers are ultraviolet absorption layers.
Tac lens material
Tac lens is made of cellulose triacetate film, which is an optical film used to manufacture polarizer. Generally speaking, cellulose triacetate with esterification degree greater than 2.7 is cellulose triacetate, and some people think that cellulose triacetate means that the acetic acid content is not less than 59%(DS2.75), but most cellulose triacetate has acetic acid content greater than 665,438+0% (DS 2.85), and its components include cosolvent, wetting agent and so on.
