True or False: Enzyme and protein remover recommended should be rinsed before application.

• A. False
• B. True
• C. Sometimes
• D. Not specified

Answer: (B)

Enzymatic or protein-removing cleaners work by breaking down residues on the lens, but they don’t automatically leave the lens completely free of residues. If you wear the lens after cleaning without rinsing, any remaining enzyme or chemical residues can come into contact with the eye, causing irritation, stinging, or more noticeable discomfort, and may affect comfort and tear film interaction. Rinsing removes these residues and helps ensure the lens is safe and comfortable to wear. Always follow the manufacturer’s guidance, but the standard practice is to rinse before applying to the eye.
