Dr. Carolyn Begley’s clinical research has spanned a wide variety of topics in the area of cornea, contact lenses, and allergy, although her main focus in the last 12 years has been dry eye. Her training includes immunology and cell biology (NEI post-doc, 1988-89) and substantial research experience in tear film and ocular surface imaging, optics and vision, psychophysics, symptom questionnaires and sensory measures, measurement of blink rate and velocity, and fluorescence measures of the tear film. She has received numerous awards, including the Garland M. Clay Award from the American Academy of Optometry for her most cited paper, Characteristics of corneal staining in hydrogel contact lens wearers. She has served as a consultant and received numerous research grants from the major optical and pharmaceutical companies in the vision care field.  She is currently funded by the National Eye Institute for a project examining tear instability as a unifying mechanism for dry eye symptoms. Dr. Begley has lectured around the world and published numerous papers and book chapters in the field of dry eye, keratoconus, ocular allergy, and contact lenses.  She is a reviewer for numerous journals, including Investigative Ophthalmology and Vision Science, Optometry Vision Science, Ophthalmology, Journal of Rheumatology, and Current and Experimental Eye Research.
