Whether or not your contacts can be used again after they have dried and soaked depends on the situation, for example, if they have been in contact with air for a short period of time and have not been contaminated with dust, they can be used, but when they have been air-dried for a long time and have become severely deformed, they cannot be used. The difference between contact lenses and ordinary contact lenses is that contact lenses are transparent and contacts have a color or pattern that is aesthetically pleasing. 1. The contact lens is an elastic contact lens that directly touches the cornea, and its own elasticity will return to its previous state after it is re-bubbled, not affecting its use again. As the process of drying for a long time may be contaminated with bacteria, using them again after softening may cause eye infections. In addition, protein and lipid deposits on the surface of the lens may cause giant papillary conjunctivitis. Secondly, when the water in the contacts evaporates, the elasticity is destroyed and the original shape is changed, so that they do not fit the eye again, causing eye discomfort and even affecting vision.
