Circle lenses are a relatively recent phenomenon. Also called “big eye” lenses, they make your eyes look larger than normal to produce a doll-like appearance, inspired by doe-eyed anime cartoon characters.
Issues concerning the safety of circle lenses have been well-documented in the U.S. media in recent years.
Many companies selling circle lenses in the U.S. do so illegally, either without requesting a prescription or selling unapproved lenses — or both.
To help avoid the risk of developing a serious lens-related eye infection, always ensure you are buying contact lenses from a legitimate source.
