The preferred method for storing a contact lens when not in use is in contact lens solution. This solution is specifically formulated to clean, disinfect, and keep contact lenses hydrated, which is crucial for maintaining the integrity of the lens material. It helps prevent the growth of harmful microorganisms that could lead to eye infections when the lenses are reinserted.

Contact lens solutions provide an appropriate pH balance and osmolality that mimic natural tears, ensuring that the lenses remain comfortable and safe to wear upon insertion. Proper storage in contact lens solution contributes to the longevity of the lenses and preserves their optical qualities.

Other storage methods, such as saline solution, are typically not recommended for long-term storage as they lack the necessary disinfection properties. Tap water can lead to contamination and potentially cause serious eye issues due to microorganisms present in untreated water. Likewise, using a permissible household liquid is not advisable, as many common liquids do not have the appropriate properties for lens care and could damage the lenses or distort their shape. Therefore, utilizing contact lens solution is the best practice for safe and effective storage of contact lenses.
