Online retail startup Ditto has developed a 3D virtual fitting room to help you find the perfect pair of glasses to suit your face. The app uses your webcam to take a series of short videos of your face turning from side to side.
It then creates a 3D model of you with a scrollable 180-degree view. You can try on as many different frames and see how they look on every side. Virtual fitting rooms are certainly on the rise as online retailers see the benefits they hold for shoppers being able to try before they buy.
