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).
What else can I help you with?
Protects the eye and allows light to enter?
Cornea
What happens to the iris to allow less light to enter the eye?
The iris contracts to allow less light to enter the eye. This is controlled by the autonomic nervous system in response to changing light conditions, helping to regulate the amount of light reaching the retina.
Which part of the eye beside the lens gathers light?
The cornea is the outermost part of the eye that gathers and focuses light onto the lens. It plays a crucial role in the initial bending of light rays as they enter the 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 the avascular structure of the eye that allow light to enter the eye?
The cornea is the avascular structure of the eye that allows light to enter. It is a transparent outer covering that refracts light onto the lens.
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 light enter the eye here?
Pupil
What is the opening which light enter the eye?
The pupil.
What allows to light to enter the eye?
pupil
How do light rays travel to your eye from a lighted candle?
Light rays travel in straight lines from a light source, like a candle, and pass through the air until they reach your eye. Once the light rays enter your eye, they are focused by the lens onto the retina, where they stimulate the nerve cells to create an image.
Protects the eye and allows light to enter?
Cornea
What part of the eye allows light to enter?
The cornea and the pupil are the parts of the eye that allow light to enter. The cornea acts as a protective outer layer that helps to focus light, while the pupil is the opening in the center of the iris that regulates the amount of light entering the eye.
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 cornea, a clear covering over the front of the eye. In low light conditions, the pupil dilates to allow more light to enter the eye. Additionally, the retina contains specialized cells called rods which can detect light even in low lighting, contributing to night vision.
Who allows the light to enter the inner part of the eye?
pupil
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.
What structure is the opening that allows light to enter the eye?
The iris has an opening, called the pupil, through which light enters the eye.
