There are several synonyms for the term "extended wear lens" which refers to contact lenses that can be worn continuously for an extended period of time without needing to be removed. Some of these synonyms include: continuous wear lenses, 24-hour wear lenses, extended wear contact lenses, and overnight contact lenses. These lenses are typically made of materials that allow oxygen to penetrate through the lens to the eye, reducing the risk of complications. Extended wear lenses are popular among individuals who need vision correction but do not want to hassle with removing and inserting lenses daily. As with any contact lens, it's important to follow proper hygiene and care instructions to avoid eye infections or other complications.
