Our May What Is It was a an eye cup. Not only used as a way to get that speck out of your eye but also to sooth tired eyes with a wash as well. Burdock root was often used to make an eye wash. Mostly oval in shape, they were filled with water or a herbal tea wash and one would bend down, fix it to the eye and raise the head to have the liquid reach the opened eye. Blinking could help dislodge a foreign object. Today you can still get them for the same handy use although some are plastic. The antique ones are very collectible and came in many shapes and colors from cobalt blue to carnival glass.
