From the Ted Talk "Andrew Bastawrous: Get your next eye exam on a smartphone"

Unscramble the Blue Letters

Once we've discovered somebody has low vision, the next big challenge is to work out why, and to be able to do that, we need to have access to the inside of the eye. Traditionally, this requires expensive equipment to examine an area called the retina. The retina is the single part of the eye that has huge amounts of information about the dbyo and its health. We've developed 3D-printed, low-cost hardware that comes in at less than five dollars to ucropde, which can then be clipped onto a smartphone and makes it possible to get views of the back of the eye of a very high uqyailt. And the beauty is, anybody can do it. In our trials on over two and half ahodustn people, the smartphone with the add-on clip is marbceopal to a camera that is hugely more sexpveine and hueygl more difficult to transport.

Original Text

Once we've discovered somebody has low vision, the next big challenge is to work out why, and to be able to do that, we need to have access to the inside of the eye. Traditionally, this requires expensive equipment to examine an area called the retina. The retina is the single part of the eye that has huge amounts of information about the body and its health. We've developed 3D-printed, low-cost hardware that comes in at less than five dollars to produce, which can then be clipped onto a smartphone and makes it possible to get views of the back of the eye of a very high quality. And the beauty is, anybody can do it. In our trials on over two and half thousand people, the smartphone with the add-on clip is comparable to a camera that is hugely more expensive and hugely more difficult to transport.
