Question

How do we see non luminous object even when they do not produce their own light?​

Answer 1

A candela is the unit of measurement for luminosity. Objects that do not emit their own light are non-luminous, and we are only able to see them when the light from a luminous object reflects off of the non-luminous object and into our eyes.
