When was the last time you replaced your contact lens case? Next to dirty hands contact lens cases are probably the most common source of bacteria that will contaminate your contact lenses. The best time to replace your contact lens case is when you get a new bottle of contact lens solution, or better yet make the move to daily disposable contact lenses and skip the contact lens case and solutions altogether.
To prevent the contamination of your contact lens case the eye doctors at Total Eye Care recommend that you thoroughly rinse the entire empty contact lens case, including the lid or caps with tap water. Next air dry your case by placing it upside down on the counter.
