Where does the light go when it enters the eye?

Where does the light go when it enters the eye?

First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in.

Which is the colored part of the eye?

When there is a lot of light, the pupil contracts to keep the light from overwhelming the eye. When there is very little light, the pupil expands so it can soak up as much as possible. Iris – The iris is the colored part of the eye.

How does the anatomy of the eye help us to see?

The anatomy of the eye allows humans to see in dim light or bright light, but not in the absence of light. The eye changes light rays into electrical signals and then sends the signals to the brain. The brain interprets these electrical signals as visual images.

How does the pupil of the eye work?

The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil (PYOO-pul). The iris (the colored part of the eye) controls how much light the pupil lets in. Next, light passes through the lens (a clear inner part of the eye).

Which is part of the eye bends light?

Cornea: The clear dome-like structure that covers the front of the eye and is responsible for bending light as it enters the eye. Pupil: The dark opening in the center of the eye that opens and closes in response to light intensity.

Where is the lens located in the eye?

Lens: Located behind the pupil, this transparent structure focuses light onto the retina. Ciliary body: Located behind the iris, this structure contains a muscle that helps to focus the lens. Vitreous humor: The clear jelly-like substance that fills the central cavity of the eye.
