Let us examine the retina closer and in more detail. Let us suppose that the pigmentary substance called "rhodopsin", operating in the retina, is absent. Rhodopsin is a substance that ceases functioning under heavy light but is regenerated in darkness. The eye cannot see clearly in dim light unless sufficient rhodopsin is produced in the eye. The function of rhodopsin is to increase the efficiency with which the eye generates a nerve impulse from dim light. This substance is produced as much as required exactly when it is needed. When the rhodopsin balance is maintained, images become clear. What would happen if rhodopsin, which is very significant for the process of sight, did not exist? In that case, man would be capable of seeing only in bright light.2 It is therefore evident that there is a perfect system within the eye, which has been designed down to the smallest detail.
Then, whose work of art is this system, which saves us from darkness and presents us a world full of colour?
Every stage mentioned thus far includes a series of processes, which require the existence of wisdom, will and power in their being brought into being. It is plain that there is no chance of such a chain of processes existing in such harmony having been formed by chance. It is also impossible for such a system to have been formed over time. The result would not change at all even if millions and even billions of years were allowed to pass. The systems to comprising a colourful world would never emerge by coincidence. Such perfect systems can come into being only as a result of special design, which is to mean that they are created. Allah possesses eternal power and wisdom that cover the whole universe. Examples of Allah's matchless artistry in creation stretch across the entire order of the universe. The unique design evident in the formation of colour is also an outcome of the peerless creation of Allah. Allah has power over all things.
(He is) the Originator of the heavens and earth. When He decides on something, He just says to it, ‘Be!' and it is. (Surat al-Baqara: 117)
