Fovea Centralis
The iris is the structure in the eye that gives it color. It is a thin, circular structure that controls the size of the pupil and regulates the amount of light that enters the eye. The amount of pigment in the iris determines the color of the eye.
The iris is the contracting membrane that regulates the amount of light entering the eye. The muscles in the iris adjust the size of the pupil to control the amount of light that reaches the retina.
The Diaphragm or diaphragm control lever regulates the amount of light passing through the slide specimen on the microscope stage.
The iris, the visible colored part of the eye, is the most anterior portion of the uvea. Shaped like a flattened doughnut, it lies between the cornea and the lens and it is continuous with the ciliary body posteriorly. It's round central opening, the pupil, allows light to enter the eye.
The iris is contained within the middle layer of the eye known as the uvea, which includes the choroid, ciliary body, and the iris. The iris is the colored part of the eye that surrounds the pupil and regulates the amount of light entering the eye by controlling the size of the pupil.
The iris, a muscular structure in the eye, regulates the size of the pupil to adjust the amount of light entering the body tube. In bright light, the iris constricts the pupil to reduce the amount of light, and in dim light, it dilates the pupil to allow more light in for better visibility.
diaphragm
The iris is the structure in the eye that gives it color. It is a thin, circular structure that controls the size of the pupil and regulates the amount of light that enters the eye. The amount of pigment in the iris determines the color of the eye.
The camera diaphragm controls the size of the aperture, which is the opening through which light enters the camera. By adjusting the size of the aperture, the diaphragm regulates the amount of light that reaches the camera sensor, allowing for proper exposure of the photograph.
The iris is the contracting membrane that regulates the amount of light entering the eye. The muscles in the iris adjust the size of the pupil to control the amount of light that reaches the retina.
The light diaphragm

iris
The biconcave structure is the "lens, but his focuses the light, it does not adjust for the amount of light. The structure that adjusts for the amount of light entering the eye is the "iris"
The function of an iris diaphragm on a microscope is to adjust the size of the aperture, controlling the amount of light entering the lens system. By changing the diameter of the iris diaphragm, you can adjust the depth of field and improve image contrast and clarity.
A diaphragm regulates the amount of light entering the microscope. Stage opening allows light to pass through the stage of the microscope.
The colored membrane attached to the ciliary body is the iris. The iris is located in front of the lens of the eye and is responsible for controlling the size of the pupil, which regulates the amount of light entering the eye.
