Who needs electricity when you have Eyenetra?

We are very happy to announce that TwoBillionEyes can now perform an eye examination with a smartphone thanks to Eyenetra's latest ground breaking innovation, the smartphone-based auto-refractor and lens metre. This means that Twobillioneyes can now perform and eye test and deliver beautiful prescription glasses to every person for five dollars, even if there is no electricity. Dear world, here we come!

Check out the Eyenetra website for more information about this terrific development.
