6 to 9 months: Generally, if you're removing them every night, cleaning and disinfecting them they can last up to 9 months or 1 yr depending on how you take care of them and how your eye reacts to the lens itself. Scratches or chips in the lens, or eye irritation from the lens is a sign to replace the lens.
