Snake eyes differ from those of mammals in that they are usually located on the sides of the head rather than facing directly in front. Snake eyes' visual system mainly relies on detecting changes in light and images, and they usually have very keen visual perception capabilities.
Snakes' eyes are generally capable of sensing surrounding motion and changes in light, but their visual systems can be relatively poor at perceiving color and clarity. Snake vision mainly relies on rod cells in the eyes, which are very sensitive to changes in light and images. As a result, snakes are able to sense the movement of their prey, the contours of the land, and other changes in their surrounding environment.
Overall, snakes do see with their eyes, but their visual systems are different from those of mammals, better adapted to sensing movement and changes in light, and less capable of perceiving color and clarity.
