TDK's 150-Nanometer Mirror Puts a Display Directly on Your Retina
Direct retinal projection display for smart glasses using a meta-optic mirror
TDK has demonstrated the world's first direct retinal projection display for smart glasses using a meta-optic mirror just 150 nanometers thick. The transparent mirror, with 80% visible-light transmittance, can be embedded in a lens, giving glasses a natural look while preventing image leakage. TDK aims for full-color operation and mass production within a few years, and has partnered with QD Laser to accelerate development.
The DRP smart glasses prevent images from being visible to people facing the wearer (image leakage). This provides a natural look and addresses privacy concerns since others cannot see the projected content.

Neat, but hardly a world first (the original title said "...the world’s first direct retinal projection display...")
I first read about direct retinal projection displays (using oscillating mirrors no less) in Mondo 2000 [^1]
Hard to find much on the "Private Eye" hardware as I guess Reflection Technology (the manufacturer) went outta business in the mid 90's
But a 700x280 display painted onto your retina that looked like a full-ish size display hovering in space nonetheless, and downright epic for 1989

For the curious, a bit more info and some pics on these sites

That's so cool finally actually glasses instead of sunglasses!

This looks strikingly similar to my 2017/20 patent:

Pretty much all my patents are being infringed at this point.
Lesson to anyone getting patents, they don’t matter unless you have $100M to fight Microsoft or oracle with. At that point might as well just keep your 100M and forget it
