Why Does My Contact Lens Case Smell? Fix It

Quick Answer

A smelly contact lens case usually means bacteria or protein buildup. Clean it thoroughly with the right method and replace it regularly to prevent eye irritation.

Diagnose and Fix the Smell

• Symptom: You notice a musty or sour smell from the case even after rinsing it with solution. Do not wear lenses from a smelly case. Stop and clean the case now.
• Likely Cause: Bacteria or protein buildup from not rubbing and rinsing the case daily, or from leaving it wet when closed. If the smell persists after cleaning, the case is likely contaminated beyond repair.
• Corrective Action: Empty the case, rub the inside and outside with your fingers using fresh contact lens solution (never water), rinse thoroughly, and air-dry upside down on a clean tissue with the caps off. Do this daily and replace the case every one to three months.
• Stop or Choose Another Option: If the smell remains after a thorough cleaning, or if you see cracks, scratches, or cloudy residue, throw the case away and start with a new one. When in doubt, replace the case—it is inexpensive compared to an eye infection.
