PC lens is polycarbonate (polycarbonate) abbreviation, PC lens is also known as space film is very light.The main performance is safety explosion-proof, you even use hammer hit it is not necessarily brokenThe history of PC material lenses is relatively shorter, but thanks to the application of high quality raw materials, and ordinary resin lenses have essential differences!At the same time, it also inherits the excellent characteristics of super impact resistance of raw materials, so this material is also commonly known as bulletproof glass after thickening
 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.Progressive lens can realize the addition of near-use positive lens through the change of the lens center line of sight, so as to solve the problem of using different lens degrees for long distance objects, medium distance objects and close objects, and reduce or compensate the use of adjusting force. It enables the wearer to realize the vision of distant, medium and close continuous images without paying too much adjustment force.

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.
