Popularity Of Circle Lenses This new fashion trend has emerged mainly because circle lenses have become more effective and affordable. It is known that over 800,000 girls in Japan, Korea and Taiwan alone, are wearing circle lenses for cosmetic purposes. People do not only want to change the color of their eyes, but they want to be noticed. One way they can do this is by wearing circle lenses. There is currently no other way to make a person's eye appear larger other than wearing circle lenses. New technological innovations have allowed circle lenses to be much more flexible and porous, allowing more oxygen to the cornea, therefore making contact lenses much more comfortable to wear. It is very common to see many actors, models and the like wear circle lenses for appearance, and it is a growing trend among young teens and adults in North America.
