object that allows part of the light pass thru?
Mirror - It is used to reflect light through the object and lenses of the eye.
The cornea
The eye does not actively capture the light rays that are reflected off the object being looked at. They pass into the eye through the cornea..
There are some objects through which light can travel, others it cannot. Light is a part of the electromagnetic spectrum and each part has a certain energy level. The energy required to travel through an object varies with the make up of that substance. The property an object has for allowing the passage of electromagnetic radiation to pass is called its transparency. An object may not allow light to pass but allow x-rays to pass because x-rays have more energy than light. There fore human flesh, for instance, is opaque to light but transparent to x-rays. There are other things involved but this is a simplified explanation.
The energy will of course also be absorbed by the object. For example, when an object is in sunlight and absorbs part of the light, its temperature will increase.

The pupil is the part of the eye through which light passes.

The cornea
The Lens. The Iris controls the amount of Light reaching the Retina.
The substage condenser is a part of the light microscope that that serves to concentrate light from the source and focus it through the object and magnify it by the objective lens.

No part of the eye "attracts" light. Light enters the eye by passing through the cornea and the aqueous humour before getting to the lens. After being focused by the lens, light passes through the vitreous humour to the retina.
The pupil is actually the absence of the iris (colored part of the eye), so it only allows light to pass through it and helps control how much light passes to the back of the eye.
No. A traffic light is a man made object, not part of the natural environment.
Light "refraction" is the bending of light as it passes through a transmitting medium, Refraction has nothing to do with black objects. A black object reflects no parts of the visible part of the spectrum, it absorbs them all. A white object reflects all parts of the visible spectrum. A red object reflects the red part of the spectrum, absorbing the rest.
