Polycarbonate Injection Molded Polarized Lenses
These polarized lenses are manufactured using an injection molding process. In addition to the other benefits of the polycarbonate lenses such as light weight and high impact resistance, we can eliminate distortion by using this process.
Also our high quality polarizing films in the lenses filter the waves of light by absorbing the reflected glare. It showed 99% of the polarizing efficiency at our performance test. Injection Molded lenses are ideal for the middle to high end collections of the sports and fashion sunglasses.
Color availability : GS(Gray Smoke), BBW(Brown) and DR(Driver)
*Additional coatings such as mirror coat, AR coat are also available.
