Three billion people around the world wear glasses, but only 150 million wear contact lenses. The main reason – price and comfort. Current contact lenses only come in one shape and size, even though our eyes are as varied as our feet. Now a new startup promises to change everything with personal 3D printed contact lenses that you can print immediately and that will be your perfect size and fit. They aren’t on the market yet – the company estimates it will take another four years – but this is a development well worth waiting for. Nicky Blackburn |
