What if my prescription changes—do I need new goggles?

No, you only need new lenses fitted into the existing insert. The goggle itself remains the same. Take the insert to your optometrist for new prescription lenses, just as you would get new glasses with an updated prescription. The insert carrier is reusable. This is one reason to choose a quality insert system—durable carriers can last through multiple prescription changes and even transfer to new goggle frames within the same brand.
