While humans tend to only think about their own vision and eyesight, eyes work in all kinds of different ways, allowing some animals to see in ways that humans can only imagine. Here are a few things you should know about a few animals with highly specialized eyes.
Like many predators, owls have their eyes located together in the front of their face, which allows them excellent depth perception during their hunting expeditions –particularly in low-light situations. Interestingly though, these massive eyes are fixed in their sockets and can barely move. This is why the owl can turn its head so far.

Nocturnal geckos have to be able to block out the bright sun during the day while still retaining excellent night vision, which is why they have long zig-zagged pupils that can tightly constrict to let in only pinpoints of light. Interestingly, while humans cannot see colors in dim moonlight, these animals can discriminate between colors and their eyes are calculated to be almost 350 times stronger when it comes to seeing color.
Gharials are ancient creatures that are practically living fossils. Despite this, they have extremely well-evolved eyes that are located in such a way that they can keep almost their entire head underwater and leave their eyes out to look out for prey. Their eyes are also primed for night vision, as a thin, mirror-like structure at the back of their eye helps reflect light that was not already absorbed by the eye back into the eye a second time. When lights are shown on the creatures at night, their eyes will reflect the light so brightly that it looks like they are glowing.
