Introduction

The word binocular is derived from the Latin word bini, meaning two, and the Greek word oculus, meaning eye. The term binocular vision refers to both eyes focussing on a single visual image. Binocular vision allows us to perceive depth and distance between the objects.

In this TACtivity, we will understand the difficulties one might experience while viewing the world with just one eye.
