The pupil does not absorb anything, it transmits light energy to the retina at the back of they eye, the retina does the absorbing. It certainly does not emit anything either, though aliens in scifi films can have glowing eyes! Some animals like cats have reflective eyes, but they are not emitting light, only reflecting incident light.
Light reaches areas that are not in direct light by means of indirect light. The indirect light reaches the areas by reflecting off other surfaces.
Often, people who take pictures will notice that their photos come out with people having bright red eyes. This is caused by the flash of a camera actually seeing the light reflecting off a person's retina.
Since black absorbs light instead of reflecting it, the black finish inside of you camera stops stray light from affecting the image formed on the film or digital sensor. This stray light includes light that strikes the lens at an angle where it is not part of the image AND the light that may be reflected off of the film or sensor. The same really occurs with the inside of the eye. The sharpest image will always be produced when stray light is properly controlled.
Giving off light, as a light source. The sun, a light bulb, and a candle are all luminous. The moon is not because it does not give off its own light but reflects it from the sun; it is illuminated.
Because there's no light reflecting at the cat's eyes.
Anything that doesn't appear black is reflecting some light to your eyes.
Our eyes are specifically designed to detect light. The objects reflecting the light change the property of light, including its intensity and color; this allows us to make conclusions about the objects it was reflected from.Our eyes are specifically designed to detect light.

No, with mirrors; but there are lenses in the ocular that do gather the light from the mirror and make an image you can see with your eyes.
The object is reflecting red light. When we see an object as red, it appears that color because it is reflecting red light and absorbing other colors in the visible light spectrum.
yes
Pigments are solid particles that produce color by selectively absorbing and reflecting light. The color we perceive is based on the wavelengths of light that are absorbed and those that are reflected back to our eyes.
We see black in the absence of light because black objects absorb all light that falls on them, reflecting very little back to our eyes. This lack of reflected light is perceived by our eyes and brain as the color black.
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.
An object that absorbs all colors in the light spectrum will appear black, as it is not reflecting any light back to our eyes.
Dog eyes are reflective because they have a layer of cells called the tapetum lucidum behind their retina, which helps them see better in low light by reflecting light back through the retina.
When you look at a white rough surface, the light reflecting off of your face scatters in different directions rather than reflecting back to your eyes in a clear and organized manner. This scattering of light prevents you from seeing a clear reflection of yourself, as the light is not being focused back to your eyes in a coherent way.
