The Ostrin lab studies environmental and behavioral influences on circadian rhythm and eye growth. Light exposure has a close link with numerous aspects of human physiology and has been implicated in several different pathological processes including myopia development, circadian rhythm disturbances, mood disorders, cancer, and metabolic disorders. The intrinsically photosensitive retinal ganglion cells (ipRGCs) are an inner retinal photoreceptor type that respond directly to short wavelength blue light, and are responsible for non-image forming functions including circadian rhythm entrainment and pupil size. Ongoing projects in the lab include 1) measuring and correlating light exposure with ipRGC activity, circadian rhythm patterns, melatonin levels and refractive error, 2) determining the effects of blue light emitting devices (computers and hand held electronic devices) on ipRGC function and sleep/wake patterns, and 3) developing devices to continuously and objectively measure behaviors related to eye growth.
Dr. Geunyoung Yoon obtained his B.S. in Physics from Sung Kyun Kwan University, South Korea and his M.S. and Ph.D., in Laser and Optical Engineering from Osaka University, Japan. Dr. Yoon went on to complete a post-doctoral fellowship at the University of Rochester’s Center for Visual Science. His laboratory’s research projects focus on the optics of the eye, vision, and eye diseases. His research goals are to objectively understand optical quality of the eye and to improve visual performance by correcting the optical defects in the eye. He has successfully developed various advanced optical systems for eye research including large dynamic range wavefront sensor for highly aberrated eyes, binocular adaptive optics vision simulator and customized ophthalmic lenses/refractive surgery.
He is a recipient of the Dolly Green Special Scholars Award, Research to Prevent Blindness and David E. Bryant Trust Research Award. He is currently a panel member for the FDA’s Center for Devices and Radiological Health.
Dr. Yoon joins the Department of Vision Sciences as a Professor.
Bifocal Lenses in Nearsighted Kids (BLINK) Study & BLINK2 Study - University of Houston College of Optometry Website
Bifocal Lenses in Nearsighted Kids (BLINK) Study & BLINK2 Study: PURPOSE To determine if soft bifocal contact lenses (typically used to help people over 40 see).
Dr. Berntsen's research interests include myopia, contact lenses, and aberrations of the eye. He conducted the Study of Theories about Myopia Progression (STAMP), a two-year clinical trial evaluating theories of juvenile-onset myopia progression. He has conducted adult and pediatric studies involving contact lenses and higher-order aberrations of the eye. Dr. Berntsen is the Principal Investigator of the University of Houston clinical site for the Bifocal Lenses In Nearsighted Kids (BLINK) Study, a multicenter randomized clinical trial sponsored by the National Eye Institute. The BLINK Study is a collaborative effort between the University of Houston and The Ohio State University that will determine whether commercially available soft bifocal contact lenses slow the progression of nearsightedness in children.

Our research primarily focuses in the areas of cornea, contact lenses and refractive error. We are currently recruiting reseach subjects.
The Richdale lab conducts sponsored and investigator-initiated research aimed to understand patient reported outcomes, safety of contact lens treatments for myopia management.
The Ritchey lab focuses in both clinical and research areas. Clinical areas include specialty contact lens fitting, anterior segment disease and ocular prosthetics. Research activities focus on myopia development and contact lenses.

Dr. Manny's research interests include development of vision, anomalies of binocular vision, refractive error, and vision screening. Clinical interests include infant and preschool vision and children with special needs. In addition, Dr. Manny leads studies in association with the Pediatric Eye Disease Research Group, and is currently investigating the effectiveness of atropine in myopia control.
The Porter lab’s main goals are to learn more about the mechanisms responsible for the development and progression of retinal diseases (such as glaucoma and photoreceptor-based degenerations) and how the retina develops in the normal eye.
Dr. Marsack's research interests include optical aberration of the eye, custom and pseudo-custom correction of optical aberration, visual performance, metrics predictive of visual performance. He is interested in the design of orthokeratology and scleral contact lenses and visual outcome.
