You should never use water to clean your lenses. Water and contact solution may appear similar, but using water in place of contact solution can potentially cause serious harm to your eyes as well as damage your lenses.
Contacts and water don’t work well together. You should not keep your contacts lenses in water, shower in contacts, or even swim in contacts. The main reason is contamination.
Bacteria is often present in common water sources, including the tap water from the sink. When your contact lenses are stored in water, bacteria and other contaminants can pass from your lenses to your eyes. Depending on the bacteria, this can lead to dry, irritated eyes or a serious eye infection.
Acanthamoeba is one of the most harmful germs to the eye. It’s frequently found in tap water, well water, and natural water sources like lakes. When the eye is exposed to Acanthamoeba, it may develop to severe corneal infection, which can be painful and slow to heal. In worse case, it can cause permanent vision loss or blindness.
Proper care of lenses is important for maintaining good eye health, and this includes the cleaning and storing habits. If you’ve exposed your contact lenses to water, it’s best to remove them and put in a new pair.
