Which of the following actions is recommended to prevent burning or discomfort when cleaning hands prior to lens handling?

• A. wash with soap and dry well, and avoid hand sanitizer
• B. use hand sanitizer to disinfect faster
• C. keep hands wet with water
• D. wipe with a damp cloth

Answer: (A)

Washing hands with soap and water and drying them thoroughly is the safest way to prepare for lens handling. Soap removes oils, proteins, and other residues that can stick to lenses or rub on the eye, helping to prevent burning, stinging, or discomfort once the lens is in place. Drying completely is important because moisture or residue on the hands can transfer to the lens and irritate the eye. Hand sanitizer, especially alcohol-based kinds, can leave a film or residue on the skin that may transfer to the lens and cause stinging or irritation, so it’s generally not recommended before handling lenses. Keeping hands wet with water won’t remove oils or debris, and wiping with a damp cloth may leave residues or fibers that could transfer to the lens.
