Up for auction is what I think is an Antq Opthamology Pinhole "PENN NO GLARE" Aluminum Eye Treatment Apparatus that I believe would have been attached to the frame of a pair of glasses. I found these with my great-grandmother's things. "PENN NO GLARE PAT 6" is impressed into the curved outer surface of the body of the apparatus. The larger piece is 1 7/8" wide by 1 3/4" tall with a 5/8" diameter hole in the center. The smaller oval eye shaped piece is attached to the larger piece with two small springs. It is 1 1/4" long by 1" tall. The hole has a 1/8" diameter. I think this smaller piece would have fit closer to the eye somehow. Pinhole glasses, as the name implies, are glasses with tiny holes poked through their lenses. Pinhole glasses are actually intended to limit the amount of light that can get in. This can be helpful in certain clinical settings, especially for people with myopia or astigmatism. Eye doctors use pinhole glasses as a diagnostic tool. When someone has an eye condition, refocusing and limiting rays of light with pinhole glasses is a way to narrow down what the cause could be.
