We are able to see because light from an object can move through space and reach our eyes. Once light reaches our eyes, signals are sent to our brain, and our brain deciphers the information in order to detect the appearance, location and movement of the objects we are sighting at.

To see an object, mainly, two things help us, Eyes and Light. Actually when a beam of light falls on an object from the source of light (mainly, sun) then this light gets reflected in all directions after striking that object. The reflected light then reaches our eyes and our brain interprets the object.
