The size of the pupil of the eye is controlled by the ______
blind spot
retina
cornea
iris
- The size of the pupil is controlled by the iris.
- Iris: This is the colored part of the eye surrounding the pupil. It expands or contracts to adjust the size of the pupil, regulating how much light enters the eye.
- Blind Spot:
- This is the point on the retina where the optic nerve leaves the eye; it's a spot with no photoreceptors, so it can't detect light.
- Retina:
- This is the layer at the back of the eye that contains cells sensitive to light; it converts light into neural signals for the brain.
- Cornea:
- This is the eye's outermost layer. It protects the eye and helps focus light onto the retina.
