What is the recommended practice regarding replacement of disinfection solution and the lens case?

• A. Replace solution daily and case regularly.
• B. Replace solution yearly and case never.
• C. Replace both only when damaged.
• D. Replace only the solution, not the case.

Answer: (A)

Keeping eye health with contact lenses relies on two simple habits: use fresh disinfection solution every day and replace the lens case regularly. Daily renewal of the solution ensures the storage environment stays properly disinfected, rather than sitting in a reused mixture that can lose potency or become contaminated over time. The lens case, even with good cleaning, can develop biofilms and harbor microbes after repeated use; swapping the case regularly helps prevent these organisms from transferring back to your lenses and eyes. Together, this approach minimizes the risk of irritation or infection and supports safer lens wear. Replacing only the solution or only the case, or doing so infrequently or only when damaged, misses the ongoing contamination risk present in both components.
