Abstract: A measuring device for creating prescription eyeglasses including a rigid eyeglasses template and a rhinometer. The template is made of a face part including two rims that are spaced apart and connected by a bridge. An earpiece is rigidly and removably attached to each side of the face part. The face part of the template is provided with a lining-up means that is precisely positioned on the outer surface of the face part. The rhinometer comprises two parts that are slidable against each other, each part having flanges comprising an angled edge. The angled edges of the flanges of one of the parts slant in an opposite manner to the flanges of the other part, each flange of one of said parts forming a pair of flanges with a flange of the other part, the spacing of said pair being variable so as to form a measuring device.
