What will cell phones do next….give eye exams?
With all of the things that a smart phone can do, who thought that an eye exam would be one of them?
Scientists at MIT recently developed an app that when combined with a $2 optical lens can give an accurate eyeglass prescriptions. Once the app is loaded, the user attaches a short, conical viewfinder to the screen of their high resolution cell phone and peers in. The app then checks the four various axis of the eye. The app not only checks the user’s vision, but also checks for other abnormalities such as astigmatism. From start to finish, it takes about two minutes to deliver a full prescription. What will they think of next??
