Keep your lens case clean.

Rinse your lens case after each use and leave it open and return to dry. Store in a clean, dry place. The American Optometric Association recommends changing case at least every three months. The same advice applies to Canada.

Do not sleep with contact lenses that are not designed for extended wear.
