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
Cooperative eye hypothesis sclera, and irises. Human eyes are also larger in proportion to body size, and are longer horizontally. Among primates, humans are the only ones where the outline of the eye and the position of the iris can be clearly seen. The cooperative eye hypothesis was first proposed by H. Kobayashi and S. Khoshima in 2002 and was subsequently tested by Michael Tomasello and others at the Max Planck Institute for Evolutionary Anthropology in Germany. Researchers examined the effect of head and eye movement on changing gaze direction in humans and great apes. A human experimenter, observed by either a human
