#277: Spinspecs

Boats have been fitted with rotating windows for some time. The idea is that, by attaching a spinning, transparent shield onto a fixed window, it will sling off any water or other debris that contacts the rotating one.

Today’s invention is to adapt this idea for use in spectacles. As a recent conscript to the ranks of the myopic, I’m now always staring at the world through lenses which pick up all sorts of grime and debris.

Most annoying is that raindrops also collect there -which limits my enjoyment of being in the great outdoors for large fractions of the year, given British weather.

Each lens would have a press-on, circular housing probably made in clear, low-friction plastic and retaining a clear disc with gear teeth on the circumference, free to rotate within it.

Each disc would be driven by a small electric motor.
