We found a fisheye lens in a vacated desk and so I tried to sync it with my iPhone’s own beady little eye. The results were poor, but they looked like this.
Eyes evolved over the milennia from light sensitive cells, eyes that resemble the stages our own eyes have passed through exist throughout the animal kingdom still. One of the most curious eyes, perhaps, was that of the trilobite, the long extinct creature of Cretaceous (I think) seas. It had calcite rods for eyes.
Creationists often refer to the eye as proof of an intelligent designer, yet optical illusions exist in abundance that demonstrate that our eyes are far from perfect. Not to mention the blind spot, and of course people being born visually impaired.
Nonetheless eyes are amazing objects, balls of liquid that focus and transmit light, I am glad of mine.
