Johnson & Johnson has bought exclusive rights to an ?intelligent? electroactive lens, developed by eVision, that uses chemistry and electrical impulses to instantly focus where the wearer looks. This company is a subsidiary of The Egg Factory, an American R&D firm run by Ronald Blum, an optometrist who sold his former company, Innotech, to J&J in the late 1990s. Innotech had developed a lens casting system that formed the basis for J&J's development of its first spectacle lens, Definity 2. This lens was first launched in October of 2000 but is apparently still being test-marketed in certain portions of the USA.
