Japan: "Smartglasses" aim laser light directly into eyes

At a May 2015 technology expo in Tokyo, Fujitsu demonstrated “smartglasses” that shine laser light into a viewer’s eye, to display images from computers or cameras. It is said to be a bit like Google Glass, with a rectangle of projected images appearing in the left eye.

The laser is full color (red, green and blue combined) and is said to be harmless. The system was developed primarily as a vision aid for persons with visual defects. According to the news story, the image does not require focusing and is projected through the eye’s lens directly onto the retina.

The story notes that “the basic idea of projecting imagery onto a retina via laser has been around for decades, but miniaturizing the optics to realize a wearable form factor had been difficult until recently.”

A Fujitsu spinoff called QD Laser helped develop the glasses. They expect to begin selling them in March 2016 in Japan, Europe and the U.S. for about USD $2,000.
