Hyderabad: Even the simplest of designs can solve complex of issues. The popular sixth century Japanese art of paper folding — Origami — has now inspired researchers in the city to design a simple paper device that enables patients self-diagnose their refractive eye defects.
The design team of city-based LV Prasad Eye Institute (LVPEI) developed a prototype of the device — Phoropter — which can completely change the existing system of detecting refractive errors.
The industrial design team of Srujana Innovation Centre, LVPEI, skillfully employed the paper folding technique of Origami to design the Phoropter, at a cost of just Rs 50.
The Phoropter comprises two sheets of papers that are folded into a shape of small oblong boxes and can slide into each other. Patients can look at the alphabet chart from one end of the box and move the other box till the chart comes into focus and a reading is collected.
“The best part is that it can be assembled even by children. The Phoropter has the potential to cut down diagnosis costs and be available for everybody. We are in the process of finding a way for mass production of the device,” Ashish Jain, industrial designer of Sujana Innovation Centre, LVPEI, told Telangana Today.
Typically, one has to spend at least Rs 1 lakh, sometime even more, to set up an ophthalmic lab and hire a qualified optometrist to operate and diagnose patients. But, the Phoropter will make diagnosis simple, especially among schoolchildren, who need early intervention to correct refractive errors.
“There was a need for a simple, cost-effective and easy-to-manufacture device that doesn’t need an expert to use or detect refractive errors,” Jain said.
