1. Light first enters the eye through the cornea. 2. The retina is the light absorbing layer of the eye that contains the rod and cone cells. 3. A cell in the retina that is responsible for black and white vision, as well as night vision is a rod. 4. A cone is a cell in the retina responsible for color vision.
Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The iris works like a shutter in a camera.
Light enters via the clear cornea of the eye. Its intensity is controlled by the adjustable diaphragm, the iris. The light passes through the iris opening called the pupil, and is focused by the lens on the retina. From the retina the light is converted into electrical impulses, conducted by the optic nerve and tract to the occipital cortex or ...
The path of light through the eye begins with the objects viewed and how they produce, reflect or alter light in various ways. When your eyes receive light, it begins a second journey through the eye's optical parts that adjust and focus light to the nerves that carry images to your brain.
Educational Video demonstrating how light enters the eye.
When light enters the eye through the pupil ("aperture"), it first passes through the lens which helps to focus the image/light rays so that they fall perfectly on the retina at the back of the eye.
The lens of our eye is a convex lens. So it basically converges the light to focus the object on retina which then detects the light and then we can see the image. The ciliary muscles change the thickness of lens so that it can focus distant as we...
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.

You can observe pupils expanding and contracting by looking closely at a person's eye when she looks toward a bright object. As more light enters the pupil, it reacts by contracting, allowing less light through. When less light is entering the eye, the pupil expands to allow more light in.
