lens ever conceived. We can be justifiably amazed that these trilobites,
very early in the history of life on Earth, hit upon the best possible lens
design that optical physics has ever been able to formulate. 113
Richard Fortey, a researcher at the Natural History Museum in
London and a professor of palaeobiology at Oxford University, said
this about the trilobite genus Fallotaspis:
We know that the first trilobites already had a well-developed visual
system. Indeed, the large eyes found in the genus Fallotaspis, from
Morocco, prove that sophisticated vision goes back at least 540 million
years to the Cambrian period. 114

The Problem and Its Solution

A spherical lens like a marble does not produce a clear image,
because the rays reaching its rounded surface must travel different
distances, and are thus refracted at different angles. The trilobite eye
overcomes this problem by means of a special arrangement. As al-
ready mentioned, the trilobite eye lens is made of calcite, the same
material, as the shell covering its body. Raw calcite crystals are
