Professor Smith received his OD (1972) and PhD (1978) from the University of Houston and subsequently joined the faculty of the UH College of Optometry. During his tenure in the College of Optometry, he has served as the Chair of the Basic Sciences Department and as the Associate Dean for Graduate Studies and Research. Professor Smith currently holds the Greeman-Petty Professorship in Vision Development and is serving as the Dean of the College of Optometry.
Professor Smith’s research interests are focused on the optics of the eye. He received the Glenn Fry Award (1996) and the Prentice Medal (2010) from the American Academy of Optometry for his research on the role of vision in regulating refractive development and eye growth. Professor Smith has published over 150 referenced papers and received 29 years of research funding from the National Institute of Health's (NIH) National Eye Institute (NEI). He is also an accomplished lecturer, having received teaching awards at the department, college and university level and in 2003 was selected by the Texas Optometric Association as its Educator of the Year.
Professor Smith is an active member of the vision science community. He is a Fellow of the American Academy of Optometry, an ARVO Fellow (inaugural class), a past President of the American Optometric Foundation (2002), a past Member and Chair of NIH NEI's Central Visual Processing Study Section (1998-2003) and a past member of NIH's National Advisory Eye Council (2005-2008). Professor Smith currently serves on the Board of Directors of Prevent Blindness Texas, as the Secretary of the Partnership Foundation for Optometric Education, and as the Past-President of the Association of Schools and Colleges of Optometry.

Scott Stevenson received his PhD in Experimental Psychology from Brown University in 1987 for studies of visual suppression during eye blinks. He was an NRSA post-doc at UC Berkeley School of Optometry for three years, and then joined the research faculty there. Dr. Stevenson joined the faculty at UH in 1995.
Dr. Stevenson’s research concentrates on the visual control of eye movements, with emphasis on visually driven eye movement reflexes, such as for the control of eye alignment. Dr Stevenson is also active in the development of eye trackers based on high magnification retinal imaging in a broad collaboration involving researchers at a number of other institutions.
Dr. Stevenson teaches in courses on Vision Science, Perception, Optometry, Eye Movements, and Matlab for Vision Science.
Dr. Stevenson serves on the Editorial Board for Vision Research, and is a member of the Vision Sciences Society.

Janice Wensveen received her Doctor of Optometry from the University of Waterloo School of Optometry, Canada, and her Ph.D. in Physiological Optics from the University of Houston College of Optometry. Dr. Wensveen is currently Clinical Assistant Professor at the University of Houston where she teaches binocular vision in class, lab, and in the clinic. Her research interests center on compromised binocular function resulting from early image degradation and strabismus.
My long-term research goals are to understand the mechanisms and principles that govern visual development, to explain how early abnormal visual experience (e.g., due to form deprivation or strabismus) can result in amblyopia and/or anomalous binocular vision and thereby, to design better interventions to preserve normal monocular and binocular vision (e.g., for infants with unilateral cataract or strabismus). My current project focuses on how the effects of normal and abnormal visual experience are integrated over time during the critical period. Recently, we have found that daily short periods of normal vision can rescue infant monkeys from the severe amblyogenic effects of much longer periods of form deprivation, and can preserve stereopsis in monkeys reared with much longer periods of optical strabismus. In addition I am developing a model of the susceptibility of stereopsis to infantile esotropia to determine whether the duration of strabismus or age at alignment influences stereopsis to a greater degree. Taken together, this work will provide a clearer understanding of the relative influences of normal vs. abnormal binocular visual experience on visual development and help to guide clinicians in managing cases where there is some impediment to normal binocular vision.
Dr. Wensveen's clinical interests include anomalies of vergence and accommodation that compromise efficient binocular vision. She works with patients to help them overcome binocular vision anomalies in the FAMILY PRACTICE VISION THERAPY SERVICE. Her secondary interest is in contact lenses.
