蟾鱼（Opsanus，Batrachoididae）的光适应眼睛表现出眼睛的光泽。脉络膜呈黄色，有黄色的银层。这是一种双层组织，由包含五边形晶体的内部虹彩片和包含双折射黄色颗粒的外部片组成。脉络膜内无黑素细胞层。在明视眼中，视网膜色素迁移到细胞突起中并包围视锥外节。视锥细胞和突起之间的空间没有色素，入射到视网膜上的部分光通过视网膜透射到银层，并被后者反射到视网膜上。图示了相关组织，并给出了透射和反射的光谱曲线。
The light-adapted eye of the toadfish (Opsanus, Batrachoididae) exhibits eyeshine. The chorioid is yellow and has a yellow stratum argenteum. This is a bilaminate tissue, consisting of an inner iridescent sheet containing pentagonal crystals, and an outer sheet containing birefringent yellow granules. There is no melanocyte layer in the chorioid. In the photopic eye the retinal pigment migrates into the cell processes and surrounds the cone outer segments. Spaces between the cones and processes are pigment free, and part of the light incident upon the retina is transmitted through it to the argenteum and reflected by the latter into the retina. The pertinent tissues are illustrated, and spectrum curves for transmission and reflection are presented.
