Accessories: None 14-Day Warranty If you don't love this phoropter as much as we do, send it back for a full refund. B + L Greens Phoropter At the turn of the 20th century, ophthalmologists A. S. Green, L. D. Green, and M. I. Green, of San Francisco, CA, designed an optometer, which they developed slowly over many years. Drs. Green teamed up with inventor Clyde L. Hunsicker of San Francisco, who applied for a patent on October 25, 1926. The title of their invention was simply an "optometrist instrument", and the text described it as an optometer. Patent 1,804,690 was granted to the Greens and Hunsicker in 1931, and sold to Bausch & Lomb, who 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 do mental calculations, the range was far higher, from +19.75 to -28.00 and with cylinders up to -7.50, the battery of cylinders was much more intuitive and easy to use, and it soon became the gold standard among eyecare professionals. It helped put the Woolf line out of the market and forced the AO line to upgrade to a completely new design, the 590, which failed to sell well, and then the RxMaster, the design that put AO on top again. With AO's key upgrade in 1967 to the Ultramatic, (essentially an RxMaster with yoked Jackson cross-cylinders), sales of Greens' Refractors slipped and production finally ended in the late 1970's, after many thousands had been sold. In spite of the fact that production stopped decades ago, thousands of Greens' Refractors are still being used today, as they are virtually indestructible, and have a devoted rank of optometrists who swear by them. {Courtesy of Wikipedia}
