Scleral tattooing Paul Mowery (aka "Pauly Unstoppable"/"Farrah Flawless"). Larratt got the idea after Dutch eye surgeon Gerrit R. J. Melles gave Shannon's then-wife Rachel Larratt an eye implant. She had a small piece of thin platinum jewelry inserted over the sclera, which is the white layer of the eye, and under the conjunctiva, which is a clear layer covering the sclera. The method Melles had developed included injecting a small drop of saline in order to create a fluid filled pocket before inserting the implant into this pocket, which would gradually shrink and leave only the jewelry behind. Shannon then imagined the
Evolution of the eye fast locomotion or navigation by vision. The rate of eye evolution is difficult to estimate, because the fossil record, particularly of the lower Cambrian, is poor. How fast a circular patch of photoreceptor cells evolve into a fully functional vertebrate eye has been estimated based on rates of mutation, relative advantage to the organism, and natural selection. However, the time needed for each state was consistently overestimated and the generation time was set to one year, which is common in small animals. Even with these pessimistic values, the vertebrate eye would still evolve from a patch of photoreceptor cells in
