Which of the following is not true about a horse's vision?

Horses possess unique visual capabilities that differ from humans. The assertion that horses have a hard time detecting movement is not true. In fact, horses are quite adept at detecting movement, which is critical for their survival in the wild. This ability allows them to notice predators and other potential threats.

When considering a horse's vision, it is important to recognize that they have a wide field of view due to the positioning of their eyes on the sides of their heads. This anatomical feature gives them almost a panoramic vision, enabling them to see a large expanse without needing to turn their heads. Horses are also able to see well in low-light conditions, thanks to a layer of tissue in their eyes that enhances their night vision.

Moreover, horses can see in color, although their color perception is different from humans; they see in a more limited spectrum, primarily recognizing blues and greens. So, the idea that they struggle with detecting movement is inaccurate and does not align with the known characteristics of equine vision.
