How often should a contact lens case be changed to ensure safety and hygiene?

Changing a contact lens case every three months is advisable to maintain optimal safety and hygiene. Over time, contact lens cases can accumulate bacteria, fungi, and other microorganisms, which can lead to serious eye infections if not properly managed. Even with regular cleaning, the materials can degrade, creating an environment that is less hygienic for storing contact lenses.

Regularly replacing the case helps minimize the risk of contamination and ensures that it functions correctly in protecting your lenses. It is also crucial to combine this practice with proper lens care routines, such as disinfecting lenses as advised and avoiding toping off solutions in the case to further safeguard eye health. This routine enhances the overall effectiveness of lens storage and contributes to the user's ocular hygiene.
