Brindze does about as well as you could expect with her weak idea, but lacking either an angle or John McPhee's talent for making any subject interesting, she's unlikely to hold many readers. Without such incentive what's the point of putting together a chapter on the history of spectacles from inventor Roger Bacon on, another on the parts and workings of the eye, one on what happens at an eye exam, and others on sunglasses, choosing frames and how optical glass is made? She even includes filler chapters on telescopes and microscopes and on eye care--what to do when you get something in one, how to watch TV. Perhaps we're astigmatic, but it looks like an inflated optometrist's handout.
