They need it as they are predators (minute ones if that) of insect so use their monocular vision to scope out food. Also they need it to search for predators or any other threats so they can make a quick escape.
Reptiles, birds, and most fish have monocular vision, meaning they can see out of each eye independently. This type of vision allows them to have a wider field of view but can result in reduced depth perception.

Monocular vision is not a disorder or condition. Monocular vision is the type of vision a horse, cow has in that they see from one eye at a time because their eyes are on the sides of their face. Humans are binocular because we see in the front.

There are no disadvantages to binocular vision when compared to monocular vision. Binocular vision provides depth perception as well as redundancy. If someone pokes one of your eyes out, you'll still have the other one. Although you would now have monocular vision, and no depth perception.You don't have 360 degree vision so it leaves us vulnerable to rear attack.
There is a variety of things that suck if you have monocular vision as I have monocular vision. Things like lack of depth perception, unable to join the military forces or air force, and people annoying you saying YOU NEED TO PROTECT YOUR GOOD EYE! One good thing that comes from it is being able to shoot better than anyone with two eyes, and having more accuracy on one target as it is quicker for monocular persons to focus with one eye than a binocular person having to close one eye.
you. Monocular vision is something you can see with only one eye. You only have a little, but you still have some. Mostly you have binocular vision (seeing something with two eyes) but one eye is always seeing something that the other cannot.

Frog vision is monocular, meaning that each eye sees a separate image rather than combining both images to create depth perception. This allows frogs to have a wide field of view to detect movement and hunt prey effectively.
