Extended wear contact lenses are, most typically, contact lenses that can be worn continuously for up to six nights and seven days. With the advent of silicone hydrogel lenses, which are better at letting oxygen through the lens to your eyes, there are now also continuous wear contact lenses that can be worn up to 30 days straight.
Most extended wear contacts are thinner than daily wear lenses and are made of silicone hydrogel. This advanced soft lens material enables EW lenses to “breathe” better than most daily wear lenses, allowing more oxygen to reach the cornea. This is especially important when lenses are worn continuously for extended periods of time.
Extended wear contact lenses can be really helpful for people with unpredictable or highly active lifestyles.
