The Research division of ESO has a dedicated team of PhD and Post graduate students under the guidance of Dr.Krishnakumar. Smt.Sundari Subramanian Department of Visual Psychophysics lab started by the generous donation of Rs.40 lakhs from the Uthrash Trust is functioning in the Venugopal Block of Sankara Nethralaya, Nungambakkam, Chennai. Such donations will make research in ESO scale greater heights.
As a part of the undergraduate curriculum, an ESO student is required to do an original research project. Knowledge and skill required for this activity is imparted to the students in the form of various courses (such as Epidemiology, Biostatistics, etc) and hands-on clinical training. Researches in various subspecialties of eye and vision care are carried out. Some of these research findings are presented in the national/international conferences and a few are published in international peer reviewed journals. Research has always been a passion of ESO students. Late Dr.E.Vaithilingam, Principal of ESO set the way for optometry research in ESO and today it has become an integral part of the curriculum.
