Description:

An ophthalmometer (aka keratometer) measures the curvature of the anterior surface of the cornea, and so is used to assess the extent and axis of astigmatism. The German physiologist Hermann von Helmholtz introduced the form in 1851. The “F. A. HARDY & CO. / MAKERS / CHICAGO" inscription on this example refers to an optical and medical supply house established in 1884.
