What is wide-angle Vision and panoramic vision
A person interested in photography should easily understand what wide-angle vision is. High-end photographic equipment includes a dedicated wide-angle lens for panoramic views, primarily used for capturing landscapes or scenery, allowing you to see most of the elements of nature, even areas you can’t see with your eyes. You can’t see all with your eyes because of binocular vision, which helps judge distance. To see more, you need to turn your head. Our vision angle is limited and suits our needs. Many animals in nature require a vision that exceeds 180°; in some cases, over 300°, which they have developed through evolution. In this blog, we will explore how the placement of eyes influences animal vision and survival.
Field of View
Before exploring the world of wide-angle vision, let’s first understand the field of view (FOV). “Field of view is the extent of the observable world visible at any moment, either to the human eye or through an optical device like a camera, telescope, or VR headset, measured in degrees (angular) or linear dimensions.” So FOV is the area that we can see without turning our head; in our case, it is 180º. This FOV is different in different animals; some have more than 180º, and some have less than that.
Eye placement and field of vision
The FOV depends upon the placement of the eyes. If you have seen the animals closely, then you can say that some animals have forward-facing eyes and some have eyes placed on their side. Mostly predators have forward-facing eyes, and prey have side eyes. Side eyes present a much wider view, which is essential for animals like deer to be on alert and have to scan a much wider area of the grassland for the predators, while forward-facing eyes offer greater depth of field, which is essential for the predators to ambush their prey.
Animals with Super Wide Vision
Some animals have excellent wide-angle vision, which helps them to survive in the predator-dominated areas. Furthermore, some predators have some unique physiological features that help them increase their FOV.
Birds of Prey
Birds of prey, like eagles and other raptors, though, have binocular vision, but it is slightly on the side to increase their field of view. Their binocular vision is compensated for by their capability to rotate their head. Some of them can rotate their head to 270º, which increases their field of view to 300º. Their binocular vision is helpful for them to focus on prey while they are flying and also to judge the depth so that they can calculate the speed at which they have to strike them precisely.
Their eyes are large and fixed in their skull; because it takes up so much of the skull, they cannot mobilize their eyes, which means they cannot roll their eyes like us. Both eyes of the eagles have two focal points, or foveae: one that looks ahead for binocular vision and another at about a 45-degree angle to the side for high-resolution, long-distance monocular vision.
Insects
Some of the insects have excellent FOV, especially dragonflies. Dragonflies have a 360º view with their compound eyes, which have approximately 30,000 lenses. They have superior motion detection and UV light perception, which is crucial for hunting. Dragonflies are excellent overall. Flies have superior motion detection; they see things in slow motion. Bees have excellent color vision and UV detection, which helps them find the nectar on flowers. Some species of butterflies see more hues than humans. Tiger beetles have excellent binocular vision, which helps them hunt easily.
Mantis Shrimp
Mantis shrimp have the most complex and excellent eyes in the animal kingdom. They feature stalked eyes that move totally independently from each other. They provide a 360º view and depth perception in each eye. Their mid-band contains 12-16 color receptors; we have only three.
These receptors allow them to see UV, visible, infrared, and even circularly polarized light, which helps them spot prey with reflective scales. They process this vast information rapidly in their eyes for quick predator/prey assessment. Each of their eyes has three parts, allowing for depth perception (trinocular vision) to be a feature unique to them.
Reptiles – Chameleon
In reptiles, chameleons are unique because they also have independent eye movement. One of their eyes can see forward, and the other can see backward. Their FOV is nearly 360º without moving their head. Though they work independently, when they spot prey, both eyes lock on it immediately.
They achieve this effect with turret-like eyes, fused eyelids, and specialized focusing. They use unique corneal accommodations (monocular focusing) and rapid muscle action for quick focus, with a high accommodative range. Each of their eyes can rotate 180 degrees horizontally and 90 degrees vertically; this allows them to focus one eye on prey and one on a threat. They have a full view of 342 degrees with only one small blind spot behind the head.
Prey animals – Deer
Prey animals like deer, cows, and horses all have their side eyes, which help them to scan the surroundings almost 360 degrees while grazing or browsing for predators. This is the advantage they have; even when a tiger is running behind the deer, the deer doesn’t need to stop and turn their head to see the tiger chasing. They can see forward as well as backward to escape the predator while navigating their way.
Conclusion
Binocular and super-wide vision is an advantage that animals have achieved through the course of evolution. Most of the prey species have evolved their super-wide vision in such a way that helps them evade the predator, while predators have developed it to refine their hunting skills.
