Hyderabad institute makes ₹35 origami-inspired eye test
An eye care institute in Hyderabad has developed the 'Folding Phoropter', a low-cost eye test inspired by the Japanese folding tradition of origami. The device, which reportedly costs under ₹35, lets patients check their own vision for refractive errors. Notably, unchecked refractive errors are the primary cause of vision impairment in the developing world.
