Contact lens cases are prone to dirt and grime?

How long have you not cleaned your contact lens case?
We all know that contact lenses need to be cleaned and disinfected every day, but we often ignore the lens case for contact lenses. Although the box is small, if it is not cleaned properly, it may become a breeding ground for bacteria, causing eye infections.

► Why are contact lens cases so dirty?

▫ Humid environment: The residual care solution in the contact lens case provides a humid environment, which is very suitable for bacterial growth.

▫ Biofilm formation: A layer of biofilm will form on the inner wall of the lens case that has not been cleaned for a long time, and bacteria will hide in it, making it difficult to completely remove.

▫ Cross-contamination: If you do not pay attention to hygiene, the lens case is easily contaminated by hands or other items.

► What harm will a dirty lens case bring?

▫ Eye infection: Bacteria in the lens case can spread to the eye through the lens, causing eye infections such as conjunctivitis and keratitis.
▫ Ineffectiveness of care solution: The presence of biofilm will reduce the bactericidal effect of the care solution, making it impossible to effectively clean the lens.

► How to clean the contact lens case correctly?
▫ Daily cleaning: After each use, rinse the lens case thoroughly with clean water and turn it upside down to dry.
▫ Weekly deep cleaning: Clean the lens case with a neutral detergent or care solution every week, and brush the inner wall with a soft brush.
▫ Regular replacement: It is generally recommended to replace the lens case every 3 months.

Although cleaning the contact lens case seems simple, it is related to our eye health, so developing good cleaning habits and regularly replacing the lens case can better protect our eyes.
