The continuous wear contact lenses are designed to be worn continuously for up to thirty nights and don't need to be cleaned. However, your eyes may not be suitable to wear the lenses this long without a break and your optometrist may recommend a different wear schedule – for example a maximum of 6 nights wear.

If you don't want to wear them all the time, these lenses should be cleaned each time you wear them, using the cleaning solution recommended by your contact lens optometrist.
