During long periods between uses, how should rigid lenses be stored?

Rigid lenses should be stored in a dry state during long periods between uses to prevent the buildup of moisture and potential contamination. Storing rigid gas permeable (GP) lenses dry helps maintain their shape and structural integrity. When kept dry, these lenses are less prone to developing deposits or being affected by growth of microorganisms, which could occur in moist environments.

While other solutions like cleaning solution, hydrogen peroxide solution, or wetting solution may be useful for short-term storage or immediate use, they are not suitable for long-term storage of rigid lenses. Using moisture-based solutions can lead to lens distortion or degradation over extended periods if the lenses are not regularly cleaned and disinfected. Therefore, ensuring that rigid lenses are stored dry is the best method to preserve their quality and longevity when not in use.
