A novel telescopic contact lens has been developed by engineers led by Joe Ford at UC San Diego. The lens can add a 2.8x optical zoom to normal vision when its mode is switched with a polarized glasses. The design uses 4 aspherical reflective surfaces and a diffractive optical element to achieve the performance and keep the lens wearable (1.17 mm thick) at the same time. The work was originally published on Optical Express. As an optical testing group, we are thinking: “how to test it”?
