SETO 1.67 Blue Cut Lens HMC/SHMC
1.67 high-index lenses are made from materials—MR-7(imported from Korea), that allow optical lenses to be made ultra thin and ultralight-weight by bending light more efficiently.
Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.
