What is lurking in your contact lens case?? I don’t think anyone would consider getting into a bathtub with used water…but it is surprising how many people will top off solutions in their contact lens cases or reuse the solution that is already in their contact lens cases~ gross! If you are a contact lens wearer, contact lens case hygiene is a must. It is an area that is often overlooked. It is recommended that a contact lens case be replaced every 3 to 6 months. I feel better recommending to my patients to change the case every time you start a new bottle of solution. So the case looks clean, is there really any harm? YES! Biofilms are continuously building in the case. Biofilm is a collection of free floating microorganisms that secrete its own protein-polysaccharide complex. Biofilms flourish in contact lens cases if not properly cared for. Others organisms often found in the contact lens cases are Staphylococci, Bacillus, and fungi.
Proper care of your contact lens case is crucial: after removing the contacts, the case should be cleaned and rinsed with your solution (NOT tap water~ there are plenty of micro-organisms in there too,) and dried after each use. Bonus: if you are in a bathroom environment, store your cases away from toilet areas to avoid air-borne sources of contamination. Lastly, change out your case regularly to avoid any contamination that may result in eye infections!
