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
Arthropod eye curved surface. Later designs used graduating lens sizes. The third eye morphology of trilobites, called the abathochroal, was found only within the Eodiscina. This morphology consisted of up to 70 much smaller lenses. The cornea separated each lens, and the sclera on each lens terminated on top of each cornea. The eye morphology of trilobites is useful for determining their mode of life, and can function as palaeoenvironmental indicators. The horseshoe crab has traditionally been used in investigations into the eye, because it has relatively large ommatidia with large nerve fibres (making them easy to experiment on). It also falls
