Research Interests

Visual Optics

Dr. He’s primary area of interest is the optics of the eye and its visual performance. He is currently investigating accommodative changes in the ciliary muscle, the crystalline lens and the wavefront aberrations of the human eye. Dr. He is also studying the influence of peripheral aberrations and chromatic aberrations on myopia development. He is using various techniques including the wavefront aberrometer, corneal topography system, Scheimpflug imaging system and OCT.
