The fact that we see things is based on LIGHT. Light from an object must come to our eyes - whether the object emits light itself, or reflects it from some other light source.

We need an source of light, an opaque object blocking the path of light, a screen behind the opaque object.
1. there mush be a source of light 2.the light must strike an object 3.the light must be reflected from the object to your eye
In a cave with zero light, you would not be able to see any reflection from a diamond since there is no light source. However, if there is moonlight, starlight, ambient light from any source, your diamond will sparkle.

-- You "see" only when light enters your eye. -- You 'see' an object only when light from that object enters your eye. -- If the object itself doesn't generate light, then light from some other source must illuminate the object, and some of that light must reflect from the object to your eye. -- In absolute darkness, there is no light, and you do not 'see'.
This is a simple answer. Our eyes require the reflection of white light from an object in order to see it. If there is zero light in a room that is totally dark we can see nothing.
No, to see objects without the presence of light is impossible. Even a little light will help you see an object. Light has to reflect from the object to the eye to allow you to see it.

how do we see things?...There must be a light source that strikes or shines on the object and reflects and to reach your eyes..,
we see things when a light source goes into our eyes or when it reflects off an object
You only "see" when light enters your eyes. In the dark, there is no light . . . the main reason why we call it "dark". Since there is no light, none can enter your eyes, and you do not see.
Anything that you can't see in a dark room. Like my shoes, for example.
