Which of the following options promotes the safe use of contact lenses?

A. Contact lens storage cases should be replaced every 3 months: Regular replacement of lens cases prevents microbial contamination, including bacteria and fungi, which can cause keratitis or other serious eye infections. Over time, biofilm can accumulate in cases even with routine cleaning, so replacing them quarterly is a key preventive measure. B. Dispose of used contact solution daily: Reusing old or contaminated solution can introduce pathogens to the eye. Daily disposal ensures lenses are stored in fresh, sterile solution, reducing the risk of microbial keratitis, conjunctivitis, or corneal ulceration. C. Remove lenses prior to using ocular medications: Administering eye drops over lenses can alter drug absorption, reduce efficacy, and increase risk of lens contamination. Removing lenses first ensures the medication reaches the cornea directly and prevents potential damage to the lenses. D. All of the above: All listed measures collectively promote safe contact lens use by reducing infection risk, ensuring proper medication delivery, and maintaining lens hygiene. Each component is an essential part of evidence-based contact lens care practices.
