The market for veterans and others with impaired vision could be well over $500 million initially, said Dr. David Godbold, national director of the Wounded Warrior Program, a charity that has started offering the glasses to veterans. Vuzix's camera- and speaker-equipped glasses, which weigh about 2.5 ounces, won the competition to supply veterans after a six-month trial, beating out Google Glass, Oculus Rift, Microsoft HoloLens, and Epson Moverio, said Sean Tibbetts, chief executive and co-founder of CyberTimez.
