Biography
At Schepens Eye Research Institute of Mass Eye and Ear, Dr. Jung’s research focuses on the interface between optical/electrical systems and human vision. He aims to uncover the principles underlying human visual perception and apply them to improve low-vision aids, such as prism glasses, field expansion devices, and visual prostheses. He is studying optical devices and imaging systems to restore vision and rehabilitate people with visual impairments. He has applied novel light-field imaging system to improve visual prostheses for people with visual impairments, such as retinal/cortical implant and sensory substitution devices (SSDs). He has also developed visual field expansion devices (various prisms) for patients with hemianopia, bitemporal hemianopia, or acquired monocular vision. He has also developed real-time light-field microscopy that captures and then simultaneously represents entire 3D volumetric information of live specimens.
Dr. Jung was awarded a Fellowship in the American Academy of Optometry in 2019.

Monocular Visual Confusion for Field Expansion
This NIH supported research studies to characterize vision multiplexing (visual confusion) such as augmented reality (AR)/see-through visual aids and apply them to develop low vision rehabilitation devices using optical engineering and display technologies. Using vision multiplexing devices, Dr. Jung is applying this key mechanism of new field expansion to see-through head-mounted display (HMD)/see-through smart glasses for field loss patients as practical mobility aids. In addition, Dr. Jung is developing a virtual reality walking device to objectively measure the mobility performance of patients with field loss in clinical settings.
Retinal Cortical Implant, Sensory Substitution Devices
This research examines the interface between optical/electrical systems and human vision, 3D imaging, and display systems that restore vision and rehabilitate people with visual impairments.
Visual Field Expansion through Innovative Multiplexing Prism Design
Patients with acquired monocular vision (AMV) are missing a temporal crescent on the affected side, while patients with bitemporal hemianopia (BH) due to lesions at the optic chiasm are missing crescents on both sides. Previous visual field expansion devices for AMV or BH required scanning into device and created a blind area (apical scotoma) of equal magnitude to the shifted view. A multiplexing prism can expand the visual field in both cases without limitations. Dr. Jung optimized the multiplexing prism design to maximize the expanded visual field and developed prototype glasses.
Active Confocal Imaging for Visual Prostheses
Dr. Jung and colleagues are developing and evaluating a novel front-end optical and video-processing system to be used with any visual prosthesis that will remove background clutter, and therefore, improve object detection and recognition, despite the prostheses’ limitations.
