Importance of Contact Lens Replacement Schedule
As all contact lenses are medical devices, it is extremely important to follow all wearing practices as prescribed by your optometrist. Failure to adhere to the recommended replacement schedule of lenses could result in bacterial infections, pain and irritation, and permanent vision loss. Contact lenses fall into one of four wear type categories:
Rigid gas permeable (RGP) lenses, also known as hard contacts, are the original contact lens. They are more resistant to lens deposits and don't need to be replaced as frequently as soft lenses. RGP lenses can last a year or longer before they need to be replaced.
