I love this gadget! They are comfortable to wear, lightweight and look real because the non-prescription lenses are polarized. You can take photos and videos with the push of a button. There's a little blue light that flashes when the device is on, but I only noticed it at night, so I just put a small piece of black tape on it and VOILA, it's regular glasses again (without anyone else knowing , which they really are! ) They also stay charged for a long time! I just love her!
