In Asia, the shape of the contact lens market is changing due to demand for specific types of lenses. One such segment is circle lenses, a type of lens that covers an area larger than the iris, giving the appearance of a larger eye. Users wear these lenses to create a childlike, doe-eyed appearance similar to that of a Japanese anime character. This trend is very popular in Asia, but will probably not expand much beyond the area due to strict regulations on contact lenses in other countries.
