Research to Prevent Blindness Since its founding, RPB grant support has been identified with virtually every major scientific advance in eye research including the development of laser surgery for eye conditions, new drugs that prevent blindness, and refinements to the intraocular lenses used in cataract surgery. Research to Prevent Blindness Research to Prevent Blindness (RPB) is a nonprofit organization created in 1960 by Jules Stein, the founder of Music Corporation of America, to stimulate research to eliminate blinding diseases. RPB makes free information available to the public on a multitude of eye diseases, and maintains an extensive, online archive of thousands of published studies
