What happens if you rinse contact lenses with tap water

Contact lenses should be rubbed with an alcohol solution and then rinsed off with a saline solution  and never with tap water.

Tap water can contain germs, so if rinsed with this, bacteria or fungi may get on the lenses and then into the wearer’s eyes and cause damage. That’s why pharmacists are quick to advise against cleaning lenses with water.

For this reason it’s also important to keep contact lenses stored in a solution in a special container.

That solution should be changed out daily, and the contact lenses case is best switched out every four weeks. It’s also a good idea to avoid leaving the case in a sunny spot, which encourages the growth of bacteria.
