March 25 news, a recent technology called Christopher's patent with 3D printing technology successfully printed its own adjustable lens. His idea was to create an inflatable bladder with two pieces of clear, neat plastic and then fill it with liquid. Different liquid filling levels can create different pressures, so that the plastic film into different shapes. In this way, adjustable lens was born. Christopher said he was inspired by Josh Silver's TED presentation, which focused on adjustable liquid-filled glasses. During assembly, he squeezed two 3D-printed frame structures together to secure the middle plastic film. He then welded two such devices and helped secure them with some 3D-printed clips. Finally, he used a heat-shrink tubing as a hose bridge connecting the syringe to the inflatable bladder, adjusting the lens by filling the bladder with water to eventually refraction.
