Historical Significance: The NVRI had developed the LogMAR system of assessing visual acuity and the LogMAR chart in 1975 (See Cat No 2686 and 2735) and it made and sold a range of LogMAR products, various visual acuity charts and near point reading cards. They became an icon of the NVRI and NVRI Director Professor Augusteyn (1991-2001) was a vigourous promoter of them. This is one variant of the LogMAR chart produced during Professor Augusteyn's directorship.
