A downloadable PDF copy of the original 1928 Genophthalmic Ophthalmometer Manual, produced for ophthalmometer model 3240 from Shur-On. This 28-page illustrated manual is a fascinating primary source document from the golden age of ophthalmic instrument manufacturing, offering a detailed look at one of the precision keratometry instruments of the early 20th century.
The Genophthalmic Ophthalmometer was used to measure the curvature of the anterior surface of the cornea — essential for the fitting of contact lenses, the diagnosis of astigmatism, and the calculation of intraocular lens power. Shur-On was a well-regarded American optical manufacturer of the period, and the model 3240 represented the precision engineering standards of its day.
With 28 pages and numerous illustrations, this manual provides operating instructions, technical diagrams, and maintenance guidance for the instrument, making it an invaluable reference for collectors, historians, and researchers with an interest in vintage ophthalmic equipment. It is also a charming artifact of early 20th century technical publishing.
This is a downloadable PDF copy of the original document.
