Details that look sharp to people may be blurry to their pets. Duke Today, May 30, 2018. Blind as a bat or eagle-eyed? Scientists compared hundreds of species by the sharpness of their sight. They found a 10,000-fold difference between the most sharp-sighted and the most blurry-eyed species, with humans ranking near the top. The researchers also created a series of images showing how different scenes might appear to animals with different acuities. The images reveal patterns that, while easy for some species to see, may be imperceptible to others.
