Before removing the contact lens, how should you clean your hands?

• A. rinse with only water
• B. use hand sanitizer to disinfect faster
• C. wipe with a towel
• D. with soap and dry well, do not use hand sanitizer (can causing burning to patient!)

Answer: (D)

Clean hands with soap and water, rinse away all soap, and dry thoroughly with a clean lint-free towel before touching a contact lens. This approach effectively removes oils, dirt, and microbes and leaves the hands free of residues that could irritate the eye or contaminate the lens. Using only water doesn’t remove oils or microbes well, wiping with a towel can transfer dirt, and hand sanitizer can leave chemical residues that may sting the eye or irritate contact lenses. Drying well after washing minimizes the chance of moisture-related contamination and ensures a safe handling surface for the lens.
