In this paper the authors provide a survey on real time squint eye detection. This is due to defective binocular vision which causes vision loss in the turned eye. The eyes need to be straight for the brain to combine the images seen by the two eyes into a single picture. This gives them 3-D vision, which allows them to judge depth. Any turn of the eye can interrupt 3-D vision, if an eye turns in, it can reduce the total field of vision. Over the years, many methodologies have been developed to detect squint eye.
