DID YOU KNOW …

Raptor eyesight is many times better than human eyesight.


How do raptors see so much better than us?

First of all, their eyes are large, and allow in much more light than human eyes do. Raptors’ eyes also are packed with many more rods and cones, meaning that they can see with a much higher resolution. That’s the key. The statistic often used to describe raptors' eyesight is eight to 10 times better than human eyesight, or eight to 10 times the resolution than the human eye. But don’t be confused. This is not like binoculars, which help you see at a 10 times the magnification.

The raptors’ secret is that they see with much greater visual acuity. They can “resolve” or “see” details at up to ten times greater distances, which is different from seeing at a 10x magnification. The best way to think about this concept is to imagine a friend walking away from you with a newspaper until you can no longer read the headline. Now let them walk 10 times further. Assuming you’re a raptor with the ability to read, you could easily make out the headline at that distance. It’s a natural gift that leaves us hopelessly outclassed.
