Description
Technical Field

Background
Color shifting lenses, also known as "photosensitive lenses". According to the principle of light color interconversion reversible reaction, the lens can darken rapidly under the irradiation of light and ultraviolet rays, block strong light and absorb ultraviolet rays, and absorb visible light in a neutral way; the transparent state can be recovered quickly after the lens is returned to the dark place, and the transmittance of the lens is ensured. Therefore, the color-changing lens is suitable for being used indoors and outdoors simultaneously, and prevents the eyes from being hurt by sunlight, ultraviolet light and glare.
The color-changing lenses are divided into a substrate color-changing lens and a film color-changing lens according to different color-changing positions of the lenses; the substrate color-changing lens is a technology that silver halide chemical substances are added into a lens substrate, silver and halogen are decomposed under strong light stimulation by utilizing the ionic reaction of the silver halide, so that the lens is colored, and after the illumination is weakened, the silver halide is combined, the color is lightened, and the glass color-changing lens is multipurpose; the film color-changing lens is specially treated in the lens coating process. For example, a spiropyran compound is adopted to carry out high-speed spin coating on the surface of the lens, and the effect of passing or blocking light is realized by utilizing the inversion opening and closing of a molecular structure according to the intensity of light and ultraviolet rays.
The color-changing coating is the most important part of the color-changing lens, generally, the color-changing liquid is coated on the surface of the lens substrate, and then the color-changing liquid is cured into a film by adopting a heat curing technology, so that the color-changing coating is formed.
For this reason, we have developed a new method for manufacturing a coating for a color-changing lens.
