Abstract: This invention relates to an optical lenses, which includes a lens substrate, a multi-layers film is set on one side of the lens substrate to block partial blue light and infrared light. The multi-layers film is formed by interactive stacking a plurality of layers of a low refractive index film (such as silicon dioxide film, the mix material film which is composed of silicon dioxide and alumina or the mix material film which is composed of silicon dioxide and silicon oxide) and a high refractive index film (such as zirconium dioxide film, trititanium pentoxide film, titanium dioxide film, tantalum pentoxide film or the mix material which is composed of zirconium dioxide and titanium dioxide), and each layer of film is used a specific thickness. So that, the optical lens can produce the effect of blocking partial blue light and infrared light without overly increased in color, allowing the user's eyes to keep cool due to partial infrared light blocking.
