Cyberpunk 2020! Omg lasers directly into the retina! Lol! Whew. I think I’ll skip this one, but it is super rad.

Bosch Gets Smartglasses Right With Tiny Eyeball Lasers
A tiny laser array paints images directly onto your retina

“Lightweight and slim, with a completely transparent display that’s brightly visible to you and invisible to anyone else, the smart glasses in this video seem like something that could be really useful without making you feel like a huge dork. But concept videos are just that, and until I got a chance to try them out for myself, it was hard to know how excited I should be.”
“A custom fitting is necessary is because of how the glasses work. Rather than projecting an image onto the lenses of the glasses themselves, the Bosch “Light Drive” uses a tiny microelectromechanical mirror array to direct a trio of lasers (red, green, and blue) across a transparent holographic element embedded in the right lens, which then reflects the light into your right eye and paints an image directly onto your retina.”
“If anything gets misaligned, you won’t see the image.”
“The concept video is a quite accurate representation of how the glasses look when you’re using them.”
Here is the concept video

Literally these are like 0.1mW VCSELs that are attenuated anyway. Advantage is that low power green and blue are very efficient, any incoherent light can simply be filtered out by the optics. https://uk.images.search.yahoo.com/search/images?p=green+vcsel&fr=crmas&imgurl=http%3A%2F%2Fwww.redaktion.tu-berlin.de%2Ffileadmin%2Fi1%2FAG_Hofmann%2FXIAMEN_U_GREEN_VCSEL_2015.jpg#id=1&iurl=http%3A%2F%2Fwww.redaktion.tu-berlin.de%2Ffileadmin%2Fi1%2FAG_Hofmann%2FXIAMEN_U_GREEN_VCSEL_2015.jpg&action=click# still waiting on a blue one but they aren’t hard to make

Just another AR competitor trying to outdo the Hololens. Laser VR to the retina has been around for a while (Avegant Glyph) https://www.amazon.com/Avegant-Glyph-AG101-Video-Headsets/dp/B01MQWK336
