Disposable soft lenses are much more popular than conventional soft lenses. These lenses are worn for a period of time and then, of course, thrown away. The most well-known disposables last for two weeks. There are also one-week and one-day disposables. These 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.
