Invisalens® takes a modern approach to improving vision, using a custom-made pair of retainers created for you and only you. These space-age retainers were created with the help of NASA from experiments on the Space Shuttle, are made of smooth, comfortable and super breathable plastic that you only wear while you sleep. Wearing the retainers will gradually and gently shift your vision into focus, based on the exact movements your eye doctor or Invisalensologist plans out for you. There are no razor blades to cut your cornea and no lasers to vaporize your eye. You just apply a gentle set of retainers before you go to bed. You’ll achieve great vision with little interference in your daily life. The best part about the whole process is that most people won’t even know you’re improving your eyesight.
