The opening through which light enters the eye is called the pupil. The pupil is located in the center of the iris, the colored part of the eye. Its size is controlled by the muscles of the iris in response to the amount of light present in the environment, with the pupil dilating in low light conditions and constricting in bright light.

The iris has an opening, called the pupil, through which light enters the eye.
How does light enter the eye?
Light enters the eye through the cornea, a transparent outer covering that helps focus the incoming light. The light then passes through the pupil, the small opening in the center of the iris, which adjusts its size to control the amount of light entering the eye.
Light enters the eye here?
Light enters the eye through the cornea, the transparent layer covering the front of the eye. Then it passes through the pupil, the opening in the center of the iris that regulates the amount of light entering the eye. The lens of the eye helps to focus the light onto the retina at the back of the eye, where the light is converted into electrical signals that are sent to the brain via the optic nerve for processing.
The opening in the center of the iris?
The opening in the center of the iris is called the pupil. It is responsible for controlling the amount of light that enters the eye by dilating or constricting in response to different lighting conditions. This helps to regulate the amount of light that reaches the retina at the back of the eye for optimal vision.
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.
What is the name of the opening through which opening light enters the eye?
pupil
Does light passes through the palpebral fissure?
Yes, light can pass through the palpebral fissure, which is the opening between the eyelids. The amount of light that passes through this opening can affect the amount of light that enters the eye and contributes to vision.

What does light pass through when it enters the eyes?
Light passes through the cornea, the aqueous humor, the pupil (which is just an opening in the iris), the lens, and the vitreous humor on its path through the eye to the retina.

Meaning of the word 'pupil'?
