Are snakes blind ?

Like all animals on the planet, snakes possess five senses. These include sight, touch, smell, hearing and taste. Separate feelings for snakes are limited. The rest are developed beyond the normal range.

The sensitivity of the snake’s eyes depends on the species. Most snakes react to the movement of an object, rather than seeing the object itself. These are usually those snakes that show activity during the day. There are also snakes that are seen in shades of black and white; for example, blind snakes. Snakes do not have centuries, in their traditional understanding. Their eyes are covered with a transparent shell.

Eyes also play a big role in the orientation of snakes, but most eyesight is not sharp. This, in particular, is due to the fact that the eye is covered with a thin and transparent leathery film, formed from the fused eyelids. This film comes off the eye with the rest of the cuticle when molting. Therefore, before molting, snake eyes cloud (the surface layer of the film exfoliates), and after molting become particularly transparent.

The dry film covering the eye gives the snake’s look a seeming stillness and coldness that so scares many people and creates myths about the hypnotic power of the serpentine gaze. The pupil of the eye in daytime snakes is round, and in twilight and nighttime they are often pulled into a vertical slit. It has a special shape in the form of a whip-like serpent, most resembling a horizontally located keyhole. This structure of the pupil provides the ability to binocular vision, in which up to 45 ° of the field of vision is covered at once by two eyes.
