Do you remember the last time you replaced your contact lens case? Using the case month after month can subject you to painful contactsinfections that can damage your vision. Our Lawrenceville, Plainsboro and Freehold, NJ, ophthalmologists, Drs. Chirag and Angana Shah, discuss the ideal contact lens case replacement schedule and explain why it's important to buy new cases periodically.

How often should I replace my cases?

Contact lens cases should be replaced at least every three months. Visit a Lawrenceville, Plainsboro or Freehold store and replace the cases sooner if they're exposed to chemicals, such as spray cleaners in the bathroom or are noticeably dirty.

Why is it important to replace contact lens cases when they look fine?

Contact lens cases that look clean may actually harbor bacteria. If you continue to use the cases, you may transfer the bacteria to your eyes, which can cause an infection. Bacteria can move from your hands to the case and may also accumulate if you fail to change the solution in your cases. Replacing your cases regularly is the key to reducing bacteria.

How should I care for contact lens case?

Good cleaning techniques will help prevent bacterial and fungal eye infections. Before you handle your contact lenses or your cases, be sure to wash your hands with soap and water. Empty both sides of the case every day and rub them with your fingers to remove biofilm build up. Rinse the wells with fresh solution, not tap water. Using tap water to clean your case can increase your risk of developing Acanthamoeba keratitis, an eye infection that affects the corneas.

Turn the case upside down on a paper towel and allow it to air dry completely before refilling it. When you buy new cases, look for cases that are produced by the manufacturer of your contact lens solution. Bacterial levels may be higher if you mix and match cases and solutions.

Frequent replacement of contact lens cases, in addition to daily cleaning, can help protect your vision.
