Reflectors made of alternating layers of flat guanine crystals (refractive index, n = 1.83) and cytoplasm (n ≈ 1.33) have evolved independently in fish scales and in the tapeta of the eyes of elasmobranchs (Gur 2017). The tapetum of the bush-baby, Galago crassicaudatus, has a similar structure, but with crystals of riboflavin (n = 1.73).
The tapetum lucidum reflects light back onto the retina, allowing for greater absorption in dark conditions. The iris lies between the cornea and the lens , and not only gives the eye its color, ( see "eye color," below ) but also allows varying amounts of light to pass through its center hole, the pupil .

Red-eye effect, a reflection of red blood vessels, appears in the eyes of humans and other animals that have no tapetum lucidum, hence no eyeshine, and rarely in animals that have a tapetum lucidum. The red-eye effect is a photographic effect, not seen in nature. Some ophthalmologists specialise in this segment. [13]
