3. Greens', Bausch and Lomb Refractors. Ophthalmologists A. S. Green, M. I. Green and, L. D. Green developed a device known as an optometer in the 20th century. This instrument was then sold to Bausch and Lomb who named it the Greens' Refractor. This instrument was the most advanced for its time Patent 1,804,690 was granted to the Greens and Hunsicker in 1931, and sold to Bausch & Lomb (B&L), which had them redesign it (patent 1,873,356, granted 1932). B&L trademarked it as Greens' Refractor and introduced it in 1934. It was far more advanced than the competition in many ways. The power could be read right off the dial without having.

To support the validity of the study a correlation was done between K's calculated from refractions done over the Bausch and Lomb Soflens contact lenses and both the K's calculated from refractions done over PMMA diagnostic lenses and the K's as measured with the keratometer. There was a significant (p less than 0.01) correlation in both series.
