Cheap eyes.

Saul Griffiths has just won an award for creating ‘a �desktop printer� for low-cost eyeglass lenses’ as well as a prototype device for testing vision in the field. Clever chap!

‘Patients need only wear the device, which looks like an oversized pair of goggles, and look at the world around them. An electronic sensor superimposed on the goggles monitors the lens in the wearer�s eye and adjusts the device�s lens to cancel the refractive errors, thus determining the correct prescription.’
