How Does The Eye React To Bright Light. This adaptation is a reflex action carried out to protect the retina. The size of the pupil changes in response to bright or dim light. The iris dilates (opens) the pupil in low light so more light enters the eye and constricts in bright light. The cornea and the crystalline lens are both important for the eye to focus light. The amount of light entering the eye is controlled by a reflex action. When it’s very bright, the iris makes the pupil smaller to prevent “overexposure.” in the. The iris is a contractile ring that determines eye color and controls the size of the pupil. Light passes through the eyeball to the retina. Light passes through the cornea and aqueous humor through a hole called the pupil. Rods are more sensitive to light. The human eye is a sense organ adapted to allow vision by reacting to light. The eye focuses light in a similar way to when you use a magnifying glass to concentrate the sun’s rays onto a piece of paper. This allows the eyes to adjust to bright or dim lights. A bit like the aperture of a camera, this controls how much light is let into the eye: The pupillary light reflex is a reflex that controls the diameter of the pupil when exposed to varying intensities of light.
