Scientists have designed a striking new contact lens that could revolutionize ophthalmology. It’s based on a spiral pattern that lets the eye focus at different distances and in varying lighting conditions.
Beyond contact lenses, its inventors say the tech could be applied to a range of miniaturized imaging systems, including consumer gadgets like virtual reality headsets, to offer more versatility and flexibility than existing lenses.
The lens, called a spiral diopter, causes incoming light to spin in an optical vortex, making allowances for the various deformations in the cornea of the eye that can happen as we age.
