Historical Significance: Bernell is a large supplier of vision test products and other materials for optometric practice. The original company was founded in 1954 by Dr. Bernard Vodnoy and his wife Nellie (hence BERnell). The company was rebuilt when it had financial problems in 1997 by two practising optometrists, Dr. Craig Andrews and Dr. Charles Shearer. It specialises in low cost binocular vision and visual training materials that could be loaned or sold to patients for home training. This kind of material lead to the abandonment from the 1980s of the synoptophore as the main diagnostic and training instrument
