Long-term lens storage should be wet or dry?

• A. Wet
• B. Dry
• C. Neither
• D. Both

Answer: (B)

Long-term storage for rigid gas permeable lenses should be dry. GP lenses keep their precise shape and edge profile, and leaving them submerged in storage solution for long periods can encourage deposit buildup and microbial growth on the lens surface or inside the case. Storing dry in a clean, dry case minimizes these risks. When you’re ready to wear them again, rinse and re-wet as needed before insertion. Wet storage is more common for short-term soaking, but for extended storage dry storage helps maintain lens integrity and cleanliness.
