MIT Technology Review : People may one day be able to prescribe their own eyeglasses. A US-based startup company, EyeNetra , is developing a smartphone attachment that can measure the refractive error of the human eye. Entrepreneur Vitor Pamplona’s prototype device consists of a viewer placed against a smartphone screen. As the user aligns red and green lines, an app calculates the focusing error. Although the device appears to diagnose vision fairly accurately, optometrists point out that there is more to vision checks than just getting a good pair of glasses: Eye health also needs to be monitored, and complicating factors may arise and must be taken into consideration. The company is testing its device in India, where optometry is not as heavily regulated and where many people can’t afford eye exams.
