Medieval scholars were particularly fascinated by the science of optics and invented eye glasses partly as a result of their studies using lenses to determine the nature of light and the physics of sight.

FORBES: Connect

The sun had dropped behind the bluffs already, so that the tops of the bare trees showed up finely spiky, like hair or fur, against a yellow glow of light from somewhere out of sight.
