Red droplets in the cone cells of kingfisher eyes may allow sight through water or glare by acting as chromatic filters.

"Kingfishers have specialized eyes and excellent eyesight. The retina of each eye has two fovea. The cone cells have a high proportion of red droplets, which may act as chromatic filters, allowing sight through the surface of the water." (Fowler and Miller 2003: 254)
