It must enter our eyes.
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
Sapphire doesn't create or produce light. If you can see it, then it must be reflecting light from something else.
The quote "It is during our darkest moments that we must focus to see the light" was said by Aristotle Onasis.
light sight
No. They are just small bits of dust, dirt, rock or ice that burn up as they enter the Earth's atmosphere which we see as a meteor. The light you see is it being burned, not a reflection of light.
I learnt in physics today that light has to enter our eye for us to see!

because light used to see an object must have a wavelength
In order to "see" something with eyes, the object must be longer than the light wave refracted from it. Molecules are too small to be refracted.
By definition, the word "visible" means something you can see. Beware: you cannot see a light ray or beam or photon as it whizzes past you. You only see those rays that enter your eye. In a dusty atmosphere you might say you can see a light beam, but what you see is that part which is scattered into your eyes.
When light falls on some object, then it absorbs all the colors of visible light spectrum except the color of the object itself which it reflects back (diffusion). So we see the color of the object .

People can't see in the dark because their eyes need light to create images. In low-light conditions, the pupils dilate to allow more light in, but there may still not be enough to see well. Additionally, the specialized cells in the retina called rods, which are responsible for low-light vision, need some level of light to function effectively.
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.
