The present disclosure provides a flexible film, an eye lens, an eye lens container, and an operation method thereof, in particular, an eye lens, an eye lens container that can change patterns, and an operation method thereof.

In general eye lenses, to make the lens colored is usually coated with a colored film or dyed directly on the lens. For example, Patent Publication No. CN104246580 B discloses a colored contact lens, which contains the central vision zone in the contact lens. Compared with the surrounding display area, the surrounding display area is a colored area. The coloring method of contact lenses is to use dyes to uniformly color the surface of the lens or partially print patterns inside the lens. For example, a colored monomer component is coated on the surface of the lens forming mold where the iris portion is formed, and after the film is formed, the monomer component for the lens is filled and polymerized. The other method is a contact lens in which the colored part is embedded in the lens material. The above methods mainly suppress the dissolution of the colorant and ensure the smoothness of the lens surface.

Patent Publication No. US20170146828A1 discloses a dyeing method for goggles and spectacle lenses, wherein the lens comprises a polycarbonate substrate, and the method includes the following steps: providing at least one component suitable for dyeing polycarbonate A liquid mixture comprising at least one dye or pigment. Dispersion medium, in which at least one dye or pigment is dispersed in the dispersion medium as a colloid; the matrix is immersed in the mixture to make at least one dye or pigment Dip into the matrix; and remove the substrate from the mixture. The method is characterized in that the dispersion medium includes a solvent for dissolving at least one dye or pigment.

However, once these ophthalmic lenses are colored or filled, the pattern is fixed and cannot be changed after the manufacturing is completed. Therefore, it is expected that there is an eye lens that can still change the pattern as required after the manufacturing and leaving the factory.
