Titmus set the standard for vision screening instruments in 1959 with the introduction of the OV7 model vision screener. Often referred to as the TITMUS, the older OV7 model as well as the later-generation Titmus Model 2, are still in use in many industrial locations, optical practices, as well as schools nationwide. The screeners are known for their durability. As the market leader, Titmus has developed the new Titmus Series of vision screeners. Designed to meet the unique needs of the 21st century, the Titmus V Series is a welcome tool because of its convenience, accuracy, and versatility.
