Contact lenses are great, but they can also lead to infection. If you are someone who uses contact lenses, understand that they are great for your eyes, but you've got to make sure you wash your hands before you put your contact lenses in. In addition, you want to make sure you clean or purify the contact lens. You don't want to be in a situation where you actually are putting an infectious agent in your eye, because when you get an infection in the eye it's very difficult to treat. It can become a serious issue if it's not taken quite seriously.
