The Rays of Light is Visible

The rays of light are visible. When the rays of light come from any source of light towards our eyes, it look like the strip of parallel and very closer beams of rays. But this strip of rays seems going towards perpendicular to the line joining our eye to the source of light and vanishes at a distance. These rays are clearly seen in darken night, room or place when the source of light is far away from us. If we are standing at a too much lightful place, then we must be reduce the radius of our pupil of eyes by eyelids to enter less and less rays facing to the source to see these rays clearly.
