Photoreceptors<span>: The light sensing nerve cells (rods and cones) </span>located<span> in the retina. Pupil: The adjustable opening at the center of the iris through which light enters the</span>eye<span>. Retina: The light sensitive layer of tissue that lines the back of the </span>eye<span>.</span>

grass goat man
50/100 40/80 30/60.
