144Disinfection of contact lenses serves primariky to
1. ARemove surface protein deposits
2. BKeep the lens surface hydrophilic
3. CPrevent the growth of bacteria, viruses, and fungi
4. DLubricate the area between the cornea and the lens
145Contact lenses are most likely to be contraindicated in individuals who

4. DCornea directly
147A corneal abrasion caused by foreign material lodged between the cornea and the contact lens
