                Rods can respond by forming only a black-and-white image, depending
           on the light received from the objects. They are designed to function even in en-
           vironments where light is minimal. However, they do not perceive the details or
           colors of the objects.
                When we are observing the stars at night, or trying to find our seat in a
           darkened movie theater, we succeed thanks to the images generated by the
           rod-shaped cells in our retina. We are able to make out objects' shapes, but not
           their colors. This is why, as the saying goes, "In the dark, all cats are gray"—in
           the dark, all objects seem to be black and gray in color. 9

                  (Figure 1.15). When light enters
                   the eye, it first passes through
                     the cornea, pupil and lens. It
                       then falls upon the retina,
                   where millions of cells convert
                   the light into electrical signals
                   and transmit them to the brain.
                      In other words, light is con-
                   verted into electrical energy at
                       varying levels of intensity,
                  thanks to which images form in
                   the brain. This is an incredibly
                  complex and advanced system,
                  evidence of the flawlessness of
                                God's creation.
