What is SANDWICH COLORING method?

The sandwich coloring method for producing colored contact lenses involves layering a colored material between two layers of clear material, and then fusing them together. Here's a more detailed explanation of the process:

• Creating the color layer: The first step in the process is to create the color layer that will be sandwiched between the two clear layers. This is typically done by mixing a colorant into a clear polymer material. The colorant used will depend on the desired color and opacity of the lens.
• Coating the mold: The next step is to coat the mold used to create the lens with a thin layer of the clear material. This layer will become the outer layer of the lens.
• Adding the color layer: The colored material is then added to the center of the mold, on top of the clear layer. The amount of colored material added will depend on the desired color and opacity of the lens.
• Adding the second clear layer: A second layer of clear material is then added to the top of the colored layer. This layer will become the inner layer of the lens.
• Fusing the layers: The layers are then fused together by applying heat and pressure to the mold. This causes the layers to melt and fuse together into a single lens.
• Finishing the lens: The lens is then removed from the mold and trimmed to the desired size and shape. It may also undergo additional finishing processes, such as polishing or coating with a protective layer.
