Abstract
A prepackaged disposable towelette and saline solution each separably held within separate sealed chambers or compartments of a disposable sealed package. The towelette is presaturated with a neutralizing solution so that, as finger residue is rubbed off and absorbed into the fabric of the towelette, the finger skin pH is also substantially neutralized which minimizes eye irritation each time a contact lens user reinstalls each contact lens. The saline solution rewets each contact lens before contact lens installation to further reduce eye irritation.
