Product Description

Progressive multifocal lenses are also called progressive lenses, which have multiple focal points on one lens as the name implies. If the lens is divided from the focus, it can be divided into single focus lens, double focus lens, multi focus lens.
The most common type of lens is the single-focus lens, which has only one luminosity; Bifocal lens is bifocal lens, many old people used to solve the problem of seeing far and seeing near at the same time, but because of its own major shortcomings and the popularity of progressive multi-focus, bifocal lens has been basically eliminated; As a milestone in the history of lens development, multi-focus lens will also be the main direction of research and development and market popularization in the future





Color-changing lenses are also known as "photosensitive lenses". Because the chemical substance of silver halide is added to the lens, the original transparent and colorless lens will become colored lens in case of strong light irradiation, so it is suitable for indoor and outdoor.
