From outside in:
Cornea-->Anterior chamber and Pupil-->Lens-->Vitreous-->Retina (10 layers but simplified = ganglion-->bipolar-->photoreceptors (rods/cones)).
Note: anatomically the ganglion cells of the retina are reached first by light; however, transduction occurs in the opposite direction from photoreceptors to bipolar cells to ganglion cells (this answer is very oversimplified).

Light enters the eye through the cornea, which is the transparent outer covering of the front of the eye. The cornea refracts the light, bending it toward the pupil. The light then passes through the pupil, which is the adjustable opening in the center of the iris, and reaches the lens of the eye. The lens further refracts the light to focus it on the retina at the back of the eye.

Where does light first enters your eye?
Light rays enter the eye through the cornea.
Protects the eye and allows light to enter?
Cornea
How many lenses does the light pass through between the light source and your eye?
how does light effect your eye? In a compound light microscope? The light passes through three lenses between the light source and your eye. The first lens is the condenser lens.. The second lens is the objective lens. The third and final lens is the Eyepiece, also known as, the ocular lens. This is the lens you look through. These are the lenses that light must pass through to get from the light source to your eye.
How do you tramsfer mcd to watt?
You can't without knowing the source of the light as candelas have an allowance for human eye sensitivity built-in, and that varies from light source to light source. For any given light source you can find a lumens per watt figures and work back from that as a lumen is adjusted to human eye sensitivity as well.
What distance is the light brightest dimmest?
The closer a light source is to your eye, the brighter it appears - intensity included. The closer you are to the source, the larger the angle of the cone; your pupil as the base and the source as the point. The larger the angle from the point, the more light entering your eye. Too close to the source and your retinal area becomes the limiting factor.
What is a source of heat which is also a source light?
Well, there are countless. In fact, any source of heat is also a source of light, although not always visible to the human eye. Nevertheless, a light bulb is a good example. Or the sun. Or any other star. Or, well, just name it...
What is the avascular structure of the eye that allow light to enter the eye?
pupil
What is light enter the eye here?

What is the opening which light enter the eye?
The pupil.
What allows to light to enter the eye?
pupil
Where does light enter the eye and how does enough light enter so that people can see at night?
Light enters the eye through the small opening in your iris called as pupil. In the night time the pupil dilates to give you more light in your eye.
Where does light first enters your eye?
Light rays enter the eye through the cornea.
What part of the eye allows light to enter?
The pupil is the part of the eye through which light passes.
Protects the eye and allows light to enter?
Cornea
How does light enter the eye?
As light enters the eye, it strikes the receptor cells of the retina, called the rods and cones.
Starting with light source describe the path the light must travel to reach your eye?
The light moves from the source in a straight line to an object and then moves into the back of your eye to your retina.
Who allows the light to enter the inner part of the eye?
pupil
