Meta Oakley Vanguard is a perfect blend of style & functionality. Dust & water resistant. Now meta sells 8 additional lenses so you can change up the look whenever you want—see last 3 photos. You can even take them to Meta or LensCrafters for prescription insert clip—made to accommodate prescription insert clip. These shades also provide superior glare protection. You can listen to your fav music, asked Shazam to name that song, ask meta what you’re looking at, ask meta to text or call someone, tell you the weather. Endless fun. Take pictures, video, etc with a touch of the hand or voice command. Great for the beach, snow, driving your convertible top down, really any outdoor activities. Comes in its box with its charging pairing case. Own many meta a.i. glasses. These are a bit too hip for a retired grandmother. Waited too long to return them.
