The light caused the rhodopsin in the rod cells to decompose. After the light was extinguished, the rhodopsin continued to break down, causing a positive afterimage. After exposure to bright light, the rhodopsin quickly breaks down and we lose our ability to form positive afterimages. The rod cells, lacking rhodopsin, cannot respond. We are left with only cone-cell vision. The chemicals in cone cells also break down, but they regenerate more rapidly than rhodopsin. To avoid cone-cell fatigue, we continually shift our eyes slightly so that the light in the images on the retina falls on different cone cells, giving previously stimulated cells time to recover.

All these structures are filled with fluid and nerve endings that send impulses to your brain. The coiled, snail-like cochlea lies in front of the vestibule. The basilar membrane stretches across the cochlea, dividing it into two parts. The upper side is separated from the middle ear by the oval window. The lower side is separated from the middle ear by the round window, or fenestra cochlea. Another membrane—the vestibular membrane—divides the upper side of the cochlea into two parts so that the cochlea contains three coiled channels.

You cannot slip lenses that are more or less convex into your eyes every time you shift your gaze from near to far or from far to near. However, you can change the convexity of the lenses you have. When you look at distant objects, your ciliary muscles relax. This increases the tautness of the suspensory ligaments and your lens becomes less convex. As you have seen, distant objects form images closer to a lens of a given convexity. The more convex the lens, the closer to the lens the images form.
