Autofocus glasses!
What with the inexorable march of time etc, I find it harder to change focus from near to far.
These glasses have refocusable lenses (from some horrible cheap dial-eye specs), a couple of little linear servos to drive them, and a couple of endoscope camera modules to track my eyes.
The focus is adjusted based on where my eyes are converging.
