Описание: The equine eye includes the eyeball and the surrounding muscles and structures, termed the adnexa.Horses may, in fact, have an ability to judge distance at high speed. They can certainly assess ground conditions quickly for a hasty escape from danger.Equine eyes have excellent visual acuity (focus) for distant objects but may find it difficult to focus on objects less than a metre away. They cope better in low light than we do, however.Most humans are trichromats, having perception of the three primary colours. Horses appear to have dichromatic capability only, much like the red-green deficiency that we call colour blindness.Horses tend to keep “half an eye on everything”, rather than focusing on specific targets.
