Measuring your face can involve using devices that calculate the distance between the eye and the lens, wrapping a tape measure around your head, taking eye measurements with a caliper, and so on – or else it can be modeled in three dimensions.
With so many software applications on the market, 3D calibration has never been so easy. It involves rotating a device (a special machine or even your smartphone) around your head that selects specific points on your face for scanning. The greater the number of points recorded by the software, the more accurate the 3D representation.
Custom-made by mail
Across the Pond, in San Francisco, a small brand called Topology Eyewear has developed a novel concept, an augmented reality application for the iPhone. How does it work? You simply download the app and take a short video of your face, making sure to turn your head to the left and then the right. The app can then use these images to create a 3D model of you. Next, you choose the style and the lenses (for sunglasses or corrective eyewear). The brand takes care of the rest! The spectacles are made by hand, from acetate or steel, and mailed direct to your home.
