Eyes are complicated biological devices, having to transmit light that creates a usable image for us to process. That means filtering out light that is unfocused, and that might interfere with the final image. When researches studies zebra fish eyes, they found that the iris has a layer of guanine crystals that reflect light back instead of absorbing it. That reflective action creates the iridescent sheen while simultaneously bouncing the light in a way that makes the fish less conspicuous in its environment.
