The quality of lens film used in Guangming optical shop is better. We have high-quality lens film, especially aspheric lens. In order to pursue the thinness of lenses, we changed the curved surface design of lenses and abandoned the traditional spherical design of spherical glasses, which is not natural and clear enough. The use of aspherical lenses will not happen, and the lenses will become lighter, thinner and flatter. Thank you for your concern?
