      i think it should be a concave mirror with a focal point on your retina for it to work

        Nah, doesn’t have to be. Just try putting a mirror very close to your eye, but angled sideways. You will be able to focus onto anything you want without issue. Because you aren’t focussing at the mirror, but at the thing you look at.
