I 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.

With 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!

Well, 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.
