Do It Yourself Healthcare

This new system, called NETRA (Near-Eye Tool for Refractive Assessment), is a project of the MIT Media Lab’s Camera Culture research group. A small plastic device—which currently can be produced for less than $2 (US)—is easily clipped onto a mobile phone screen. To use it, simply hold the device up to the eye, look into it, and use the phone’s keypad until two patterns overlap. This is repeated several times per eye, with the patterns at different angles. The whole process takes about two minutes, during which time software loaded onto the phone computes and provides the data needed to create a prescription.
The small size and low cost of the device makes it especially well-suited for use in the developing world. As many as two billion people worldwide have refractive errors of the eye, and according to the World Health Organization, these errors, left uncorrected, are the world’s second-highest cause of blindness. This is just the beginning of the many ways technology innovation will fill in the gaps in health service, placing our health literally in our hands.

Wow, “second-highest cause of blindness”!
Detectible by $2 piece of plastic and a cell phone.
This is an impressive gift to humanity.
What is “society” waiting for?
I’m continually stunned at how smart some folks are.
