The Defense Advanced Research Project Agency (DARPA) said today’s night vision goggles are too heavy and cumbersome for troops and have led to short term and long term neck injuries.

DARPA officials have put out a call to companies to issue proposals to build the next generation of night vision goggles. Proposals must put forth a plan to design goggles that look a lot like a bulky pair commercial sunglasses. The night vision glasses must be able to instantly switch from daylight to infrared.
