Course Description The course aims to make the students to be familiar with the basic knowledge of the optics, refraction and binocular vision. The course will firstly focus on understanding of the light and its clinical implications. This knowledge will help to know the different optical condition of the eye. Once they are competent on the optics of the eye they will be educated on the techniques to measure refractive error and refine it. The other part of the course provides knowledge on eye teaming and focusing to perceive the world in synchronized manner, how the eyes will behave once this harmony is disturbed. This knowledge will help them to identify different binocular vision abnormalities. This allows them to assist in the clinical management of the cases with binocular disorders.
