When I test my minimal focus distance it's around 10cm (4"). What's the tech behind it, to display anything that can be sharp in such a small distance?

- detaro 5y agoThe optics mentioned will project the light so the display appears to be much further back, and your eyes have no trouble focusing on that virtual image.
- dosenbrot 5y agoWithout knowing if this has anything to do with these glasses I remember something called „in eye projection“. The trick is to create the image with a laser direct in the eye ignoring the focus distance, line a hologram. A quick search shows something like this https://www.osa-opn.org/home/newsroom/2018/october/optical_display_creates_images_in_the_eye/ https://www.osa-opn.org/home/newsroom/2018/october/optical_d... .
- baybal2 5y agoJust have an eye projection made through some aperture narrowing lens system to flatten the depth of field
- mclightning 5y agoI worked with Sony SmartEyeglasses. Yes, it is possible. There are many many ways to achieve that. Oculus Rift display is also pretty much up close your face, but you can focus.
- trzeci 5y agoWith that I thought there are lenses between eyes and screen that make it possible. With smart glasses I couldn't see any opportunity to alter the visual rays. // Thanks for other comments how it could be possible!
- mclightning 5y agoWell, that's to give a familiar example. I don't believe most people are familiar with waveguides whereas VR headsets are widely available these days.
