Description

Flexible film, spectacle lens, spectacle lens holder, and method of operation thereof

The present disclosure proposes a flexible film, spectacle lens, spectacle lens holder, and operation method thereof, especially spectacle lenses with variable patterns, spectacle lens holder, and operation method thereof.

In general spectacle lenses, to make the lenses have color, it is usually coated with a layer of colored film, or directly dyed on the lenses. For example, the patent notification number CN104246580 B discloses a colored contact lens, which includes a central vision area in the contact lens. The surrounding display area is the colored area, and the coloring method of the contact lens is to use dyes to uniformly color the lens surface or partially print patterns inside. For example, the surface of the lens molding die where the iris portion is to be formed is coated with a colored monomer component, and after forming a film, the monomer component for the lens is filled and polymerized. Another method is a contact lens in which the colored part is embedded in the lens material. The above-mentioned methods mainly suppress the dissolution of the colorant and ensure the smoothness of the lens surface.

In the patent publication number US20170146828A1, a method for dyeing goggles and spectacle lenses is disclosed, wherein the lenses include polycarbonate substrates, and the method includes the following steps Step: providing a liquid mixture of at least one component suitable for dyeing polycarbonate, said mixture comprising at least one dye or pigment. a dispersion medium in which at least one dye or pigment is dispersed as a colloid; immersing a substrate in the mixture so that the at least one dye or pigment is impregnated into the substrate; and removing the substrate from the mixture. The method is characterized in that the dispersion medium comprises a solvent for dissolving at least one dye or pigment.

However, once these spectacle lenses are colored or filled, that is, the pattern is fixed and cannot be changed after the manufacture is completed, so it is expected to have a spectacle lens that can still change the pattern according to requirements after manufacture.
