I've been looking at a variety of diverse blogs and noticed a video on 2000ah.blogspot.com that caught my attention. Essentially, a Japanese company has developed glasses with a mount that projects images directly on the retina. This is another case where science has caught up to science fiction.
You can watch the video of the device below.
Although the Japanese glasses seem more technologically advanced, an Israeli company had previously developed glasses in 2006 that projects videos on the lens.

As I dug deeper into when this technology came about, I found out that a U.S. company developed head-mounted displays in 2002.

Even before that, in 1993, a patent was filed for fiber-optic video glasses, which can be found at the U.S. Patent website here.
So if this technology has been around for so long, what's taking it so long for it to be mass marketed? It's expensive to make, so we probably have wait a long time. When the crave for this technology matches the price customers are willing to pay, then perhaps we'll see these glasses next to the 3D TVs for sell.
