Good lens hygiene starts before a lens touches your eye. Wash your hands with soap and water, then dry them with a clean, lint-free towel. Handle lenses over a clean surface, and avoid touching them after applying lotions or cosmetics. Keep the lens case and solution bottle clean, capped, and away from areas where splashes or debris can reach them. Small habits are easier to maintain when you do them in the same order each time.
For reusable lenses, follow the specific cleaning instructions provided for your lens and solution. Rub and rinse lenses only if the product directions call for it, using fresh disinfecting solution rather than water or saliva. Empty the case after each use, let it air-dry as instructed, and replace it regularly according to professional guidance. Never reuse old solution or mix products unless your eye care professional confirms they are compatible.
Keep lenses away from tap, bottled, and recreational water, including showers and swimming pools. Water exposure can introduce microorganisms that may cause serious eye problems. If lenses get wet, ask your practitioner what to do rather than guessing. Remove lenses before sleeping unless your professional has specifically prescribed an approved overnight-wear schedule. Seek prompt advice for pain, redness, light sensitivity, discharge, or changes in vision, and do not put a suspect lens back in.
