How Glass Eyes Wear Out.

The most perfect eyes are made in Thuringia, Geimany, and have a more natural appearance than any others. The iris is covered with silver and tbe blood vessels with gold, and, when properly inserted, they will move almost as readily as their natural companion. Of course much depends upon the condition of socket and the state of the muscles as left by the surgeon. Ou> greatest trouble is the matching of the eyes. You see, eyes wear out, their life being about a year or a little over, though occasionally I see one that has lasted a much longer time. The salt and alkaline solutions of the tear ducts, however, have an effect on the surface of the glass, and eventually roughen it, so that a new eye is necessary. Here’s one, you can seß how rough its surface is and how its colors are dimmed.— Philadelphia Frees interview.
