Often sought after, they have been rarely available as they are a recent arrival on the scene.
The clever design incorporates built in lower bifocal segments, making one pair of glasses double as reading glasses and safety glasses as well as protecting from sunshine or glare. This does not, however compromise your distance vision when you look up as the top section is not magnified - so you can keep them on for all your tasks/games and walk around freely.
