The brainiacs at MIT are known for being good with numbers, but this goes a little bit past that. The scientists have figured out how to use a kind of holographic refraction light science which allows information to be extracted from all kinds of different angles. It may sound like a bunch of jargon at first, but basically now your Nexus One -- and is that a Samsung Behold up there?!!? -- can be used by optometrists to calculate your eyeglass prescription. Of course, you will need to purchase to $2 tube that enables the light refraction, and then attach it to your phone running the special alignment Android app to get everything to work. Other than that, you’re ready to open your own glasses shop – just be sure to get your license first. And don't forget to check out the video after the break.  [Vizworld via MIT Media Lab]
