MIT is on the verge of creating what could be the single most useful tool for optometrists around the world. By retrofitting a Nexus One with a microlens array or pin-hole array and then shooting beams of light into a person's eye, they can figure out whether you have myopia, hypermetropia or astigmatism and, if so, how bad it is.
The microlens array allows the phone to create a "4D interactive high-resolution light-field display" near your eye. This virtual display creates objects and places them at varying depths ranging from 1 cm to "beyond infinity". Basically, they've invented a vision test that doesn't rely on physical distance and can be administered (one presumes) anywhere at any time.
This technology has huge implications for patient eye-care, both here and in the third world. Those of us in wealthy nations can look forward to doing a pre-exam at home with our phone and shaving a few minutes off of our optometrist visit. Overworked doctors in poorer parts of the world will now have the option of doing more tests in a shorter period of time with extremely portable equipment.

The “geek mind” is concerned with more than just the latest iPhone rumors, or which company will win the gaming console wars. I4U is concerned with more than just the latest photo shoot or other celebrity gossip.
The “geek mind” is concerned with life, in all its different forms and facets. The geek mind wants to know about societal and financial issues, both abroad and at home. If a Fortune 500 decides to raise their minimum wage, or any high priority news, the geek mind wants to know. The geek mind wants to know the top teams in the National Football League, or who’s likely to win the NBA Finals this coming year. The geek mind wants to know who the hottest new models are, or whether the newest blockbuster movie is worth seeing. The geek mind wants to know. The geek mind wants—needs—knowledge.
