The iris is the coloured part of the eye. It's typically brown or blue, but other colours like green or grey are possible.
The pupil looks like a black dot in the centre of the iris. It can dilate (get wider) and contract (get smaller). The size of the pupil changes depending on how bright the light is. If you are in a very bright room, or in bright sunlight, your pupils will be very small. This is because not much light needs to be let in to the eye for it to be able to see well. In a dimly-lit room your pupils will be bigger, to let as much light into the eye as possible.

What is the black hole in the center of the iris?
The black circle in the middle of the iris in your eye is called a pupil. It dilates to adjust with sunlight.
What is the opening that is controlled by the muscles of the iris?
The opening that is controlled by the muscles of the iris is called the pupil. The iris is responsible for adjusting the size of the pupil in response to different lighting conditions.
What part of eye makes the pupil smaller in bright light and larger in dim light?
The iris is the part of the eye that controls the size of the pupil. In bright light, the iris constricts the pupil to reduce the amount of light entering the eye, while in dim light, the iris dilates the pupil to allow more light to enter and improve vision in low-light conditions.
What structure is the visible colored part of the eye that controls pupil dilation?
The visible colored part of the eye that controls pupil dilation is the iris. The iris regulates the size of the pupil in response to light conditions and helps to control the amount of light that enters the eye.
The colored part of the eye that contains muscles to contract or expand the pupil is the?
The colored part of the human eye that controls how much light that passes through the pupil is called the iris.
What causes difference in the coloration of your eye pupil?
The pupil is allways black. The iris is the colored part.
What is the black hole in the center of the iris?
The black circle in the middle of the iris in your eye is called a pupil. It dilates to adjust with sunlight.
Which part of the eyes control size of the pupil?
The iris, specifically the muscles within it, control the size of the pupil. Contraction and relaxation of these muscles regulate the amount of light entering the eye by adjusting the diameter of the pupil.
Is it possible for your pupil to grow bigger than your iris?
No. The pupil can only open to the size of the iris.
What is the opening that is controlled by the muscles of the iris?
The opening that is controlled by the muscles of the iris is called the pupil. The iris is responsible for adjusting the size of the pupil in response to different lighting conditions.
Where is the iris located?
The iris is the layer that surrounds the pupil and controls the size and diameter of the pupil. It also controls the amount of light that reaches the pupil.
What is the difference between shape of cat iris and tiger iris?
The iris of a cat is typically round with a vertical slit-shaped pupil, allowing for better vision in low light. In contrast, the iris of a tiger is round with a circular pupil, which helps them track and focus on prey during daylight hours. This difference in pupil shape is primarily due to their differing activity patterns and hunting strategies.
What are the rings of muscle around the pupil gives the eyes color?
it is known as Iris. contraction or relaxation of iris alters the size of pupil.
How does the iris control the size of the pupil?
the iris
How are the pupil and iris related to each other?
The iris is a muscle that adjusts to allow more or less light into the pupil.
What is the name of the colored muscular diaphragms that surround the pupil?
The colored muscular diaphragms that surround the pupil are called the iris. They control the size of the pupil to regulate the amount of light entering the eye.
Colored part of the eye that contracts or relaxes in response to light?
The Iris contains the muscles that control Pupil size.
