This happens because of sensory adaptation . 9) Rods are the sensory receptors related to peripheral vision. 10) The part of the eye that dilates or constricts to adjust the amount of light that enters the eye is the iris . 11) The retina houses the rods and cones that are the receptors for the senses of sight. 12) Rods are generally more sensitive to brightness than cones except for the red portion of the colour spectrum. 13) Dark adaptation refers to the progressive improvement in brightness sensitivity that occurs over time when you are trying to see in low illumination. 14) In low illumination, the cone receptors in the eye adjust to light after 10
