Understand how optics and biology limit normal and pathological visual performance.

Play a leading role in the advancement of Clinical Vision Science with the specific goal of employing advanced basic vision science to resolve clinical problems.

Support development novel vision-based technologies with core knowledge of human visual function.

Provide a high quality and stimulating learning enviorment when training students, optometrists , research scientists and industry teams.

Dr. Arthur Bradley divides his time between running a visual optics research lab and teaching in the professional Doctor of Optometry program, the Ph.D. in Vision Science program, and an Introduction to Vision Science undergraduate class. His interests are centered around visual perception, and the impact of the eye’s optics on visual function.

Current research has examined the effect of novel contact lens designs on presbyopic vision, the functional consequences of interocular differences in optical quality, and the determination of spherical refractive error in aberrated eyes.

Dr. Bradley is a consultant for the contact lens and IOL industries as well as NIH, FDA, USDOD, NSF and others. He is actively involved as journal referee, topical editor or editorial board member for most journals in Visual Optics, Optometry, and Ophthalmology.

Ph.D., University of California, Berkeley (1983)

Dr. Bradley’s current research has examined the effect of novel contact lens designs on presbyopic vision, the functional consequences of interocular differences in optical quality, and the determination of spherical refractive error in aberrated eyes.  As concern over the global pandemic of myopia has emerged, Dr. Bradley’s lab has begun examining the optical characteristics of young eyes, and especially the retinal image quality before and during myopia control therapy.
