Sensation_ Perception And Attention In Psychology — Part 1 MCQs with Explanations

The eye, like a camera, has a mechanism that controls the amount of light entering it. This is done by the iris, which is a muscular structure that adjusts the size of the pupil, thereby controlling the amount of light that enters the eye. The iris functions similarly to the diaphragm of a camera, which regulates the light entering through the lens. Key Points: >> The iris adjusts the size of the pupil, which in turn controls how much light enters the eye. >> This mechanism is crucial for proper vision in different lighting conditions. >> The rods and cones in the retina are responsible for detecting light, but they do not control the amount of light entering the eye. Therefore, the iris is the correct mechanism for controlling light entry in the eye.
