[br]b. 18 February 1834 Zeist, near Utrecht, the Netherlandsd. 18 January 1908 Utrecht, the Netherlands[br]Dutch ophthalmologist who developed scientifically based visual testing types.[br]Snellen took his degree in medicine at Utrecht in 1857, and after continued study was appointed Lecturer in Ophthalmology and Surgeon to the Hospital for Diseases of the Eye. In 1877 he succeeded Franciscus Cornelius Donders, an outstanding figure in the development of the understanding of the optics and physiology of vision, as Professor. He held this post until 1899 when he was succeeded by his son.Although involved in virtually all aspects of the speciality, he particularly laid the basis for the scientific recording of visual acuity with the publication of his Optotypes in 1862. Optotypes were based on the concept of an average standard of vision permitting the discrimination of separate objects which subtended an angle of one minute of arc on the retina. While the concept does not take into account aspects of vision such as perception, it has stood the test of time in terms of practicality, even when abstract figures such as Landolt's rings replace the lines of single letters of the original.Snellen originated many other advances of a surgical nature, his procedure for eyelid deformity is still practised, and he developed the use of glass in the manufacture of artificial eyes.[br]Principal Honours and DistinctionsHonorary Member and Bowman Lecturer, Ophthalmological Society, UK.Bibliography1862, Optotypes/Ad visum determinandum, Utrecht. 1874, Des Functionem Sprungen.1862, Scala tipografica per mesurare il visus.Numerous papers in Graefes Archiv für Augenkinde and the Graefe-Saemisch Handbuch.Further ReadingS.Duke-Elder, 1969, System of Ophthalmology, London. 1973, The Foundations of Ophthalmology, Vol. 5.MG
