4. Contact lenses
This is pretty obvious since we’re talking about an item that is super delicate. Despite this, a lot of people think it’s normal to keep their contact lenses in water over night. Such a mistake! Don’t be one of those people and protect your lenses by avoiding cleaning them with water. You should always disinfect them with a special product that can eliminate bacteria from them.
In this case, water will make the bacteria multiply and it will affect your cornea. Don’t forget that tap water is not sterile and you must avoid it, especially if you want to clean your lenses.
