I remember that, about one to three years ago, there was a news story regarding colored contact lenses. After examining all the colored contact lenses available on the market at the time, it reported that only one brand adopted a "sandwich" design. Like a sandwich, this design has multiple layers and it put the colored layer in the middle. It protects the eyes better by reducing the risk of infection caused by peeling pigments. Can you please tell me which companies are using this sandwich design now?
