Off to get another pair of eyeglasses.

In a sense I'm buying purpose-built sets of eyes: a set for things near to me, a set for things far from me, and now a set for things far from me in very bright light. I will probably eventually have to get another couple specialty pairs as well, for example for very close-up work.

More literally, I'm buying sets of lenses. Somewhat like fixed-length camera lenses with a very clever yet awkward hack for providing focus adjustments without moving parts.
