Don't know if this would be of use, but Dave Prowse was on one of those shopping channels one evening during a star wars night. He mentioned that during filming, it was noticed that the lenses were so transparent that when the lights were shone, you could see his eyes. They Thickened the lenses in order to couteract this to the point he could hardly see. Though he did not state what color they were.
