{{use dmy dates|date=July 2013}}{{use list-defined references|date=July 2013}}{{Use British English|date=July 2013}}Leuckart's law is an empirical law in zoology that states that the size of the eye of an animal is related to its maximum speed of movement; fast-moving animals have larger eyes, after allowing for the effects of body mass. The hypothesis dates from 1876,^[1] and in older literature is usually referred to as Leuckart's ratio.^[2]

The principle was initially applied to birds; it has also been applied to mammals.^[3]

Criticism

A study of 88 bird species, published in 2011, found no useful correlation between flight speed and eye size.
