You should replace your contact lens cases regularly to protect your contact lens from coming into contact with bacteria. When you use your lens case regularly, microorganisms like bacteria will gather on its surface. Keeping your contact lenses in them makes them a potential source of infection.

Another reason you should replace your contact lens case is that regardless of the number of times you clean your case and the effort you take to maintain it, as time goes on, patches of bacteria and microorganisms will accumulate and become attached to your contact lenses. This can lead to a serious eye infection.

In addition, if you don’t replace your contact lens case regularly, it is prone to wear and tear that comes from moving it around. In time, it begins to leak and becomes less protective, making it less effective.

Now that you know why you should replace your contact lens case, let’s talk about when you should change your contact lens case.
