The Dunn Vision Reference is a glossary containing over 3700 terms relating to optometry, ophthalmology and vision science. This pocket guide is an indispensable tool for medical and optometry students. Definitions are deliberately brief in order to provide the most important facts at-a-glance.

Dynamic links between terms allow easy navigation.

Topics covered include ocular anatomy and physiology, optics, ocular pathology, clinical techniques, visual perception and psychophysics, low vision, dispensing and orthoptics.

The app, and its content, are the work of Dr Matt J Dunn; a vision scientist, optometrist and lecturer at Cardiff University. The entire contents are provided free of charge, and are aimed at students, clinicians, and the vision science community.
