    Extended wear contact lenses, is not like the normal contact lenses, which you can wear overnight. Its function is similar to the other types of contact lenses. However, some people would think it's too risky to wear the extended contact lenses due to some shortcomings. Because it's easy to accumulate bacteria and other potential dangerous microorganisms on the extended contact lenses. Also it reduces the oxygen supply to eyes thus it increases the risk of infection.
