Key Points
- The retina is a light-sensitive layer of tissue located at the back of the inner eye.
- It functions like the film in a camera, receiving the image formed by the lens.
- The retina converts light into electrical signals, which are sent to the brain via the optic nerve.
- Photoreceptor cells, namely rods and cones, are essential components of the retina, responsible for vision in low light and color vision, respectively.
Additional Information
- Cornea
- The cornea is the transparent, dome-shaped surface that covers the front of the eye.
- It helps to focus incoming light onto the retina.
- The cornea provides approximately 65-75% of the eye's total focusing power.
- Iris
- The iris is the colored part of the eye surrounding the pupil.
- It controls the size of the pupil and thus the amount of light that enters the eye.
- Pupil
- The pupil is the black circular opening in the center of the iris.
- It regulates the amount of light that enters the eye by expanding and contracting.
- Photoreceptors
- There are two main types of photoreceptors: rods and cones.
- Rods are responsible for vision in low light conditions, while cones are responsible for color vision and detail in bright light.
