Daily (single use) contact lenses are not meant to be cleaned and should be discarded after every use. Single use contact lens materials are not intended for prolonged exposure to cleaning/disinfecting solution and some materials may even break down when exposed to these cleaning solutions for the duration of a cleaning cycle (approx.. 6 hours). Do not clean daily (single use) contact lenses other than rinsing them with all-in-one cleaning solution to aid in insertion if desired.
