Is it difficult to clean the contact lenses?

It is not difficult once we have some practice. For contact lens wearers, it is best to remove lenses before showering, swimming, or using a hot tub. Contact lenses should never be rinsed or stored in water. It is important to wash and dry hands well before handling lenses and to clean contact lens cases with solution rather than water to avoid contaminating the lenses with germs found in water like Acanthamoeba.
