Researchers at MIT have developed a cheap and easy to use system, called Catra, that uses a cameraphone clip-on device to map out cataracts.
The technology functions by sweeping the eye with a beam of light and using the phone’s camera to detect fuzzy spots. It can provide both a map of the cataracts and maybe help make an overall assessment of whether surgery might be necessary.
From MIT News:
While the standard test for cataracts in an ophthalmologist’s office assigns a score on a scale of 1 to 4 — from no cataracts to completely blocked vision — the new, inexpensive test actually provides much more information. Media Lab graduate student Vitor Pamplona, a member of the team developing Catra, explains that it “scans the lens of the eye and creates a map showing position, size, shape and density of cataracts.” Read more »
