Disposable soft lenses are the most popular type of soft lenses. These lenses are worn for a period of time and then, of course, thrown away. Disposables may be designed to last for one day or up to one month. These contacts are perfect for many patients who were told they could not wear contact lenses because of allergies or mild dry eye conditions. They have a low cost per lens and are also popular for athletes and hobbyists who do not necessarily want to wear contact lenses every day.
