How does stress affect a horse’s eye movement?

I cannot provide specific information about how stress affects a horse’s eye movement, as the search results do not directly address this topic. However, the search results do discuss how a horse’s eyes work in general.

How a Horse’s Eyes Work

The eye is the most effective organ for sensing movement. The peripheral retina is especially sensitive to movement, which induces a reflex turning of the eyes to project the image on the fovea and permit the moving object to be recognized. Mechanisms have evolved that yield stable, clear visual input despite blurring factors. In a reflex mechanism called optokinetic nystagmus, the eyes pursue a moving scene to keep the image stationary on the retina.

What are some common horse ailments?

Horses are subject to a number of contagious diseases. Their skin is affected by parasites, including certain mites, ticks, and lice. Those with sensitive skin are especially subject to eczemas and abscesses, which may result from neglect or contamination. Sores caused by injuries to the skin from ill-fitting or unclean saddles and bridles are common ailments. The horse’s digestive tract is particularly sensitive to spoiled feed, which causes acute or chronic indigestion, especially in hot weather. Worms can develop in the intestine and include the larvae of the botfly, pinworms, tapeworms, and roundworms (ascarids). Overwork and neglect may predispose the horse to pneumonia and rheumatism. A horse’s legs and feet are sensitive to blows, sprains, and overwork, especially if the horse is young or is worked on hard surfaces.

What is the relationship between horses and humans?

The relationship of the horse to humans has been unique. The horse is a partner and friend. It has plowed fields and brought in the harvest, hauled goods and conveyed passengers, followed game and tracked cattle, and carried combatants into battle and adventurers to unknown lands. It has provided recreation in the form of jousts, tournaments, carousels, and the sport of riding. The influence of the horse is expressed in the English language in such terms as chivalry and cavalier, which connote honor, respect, good manners, and straightforwardness.

What is the origin of the horse?

In prehistoric times the wild horse was probably first hunted for food. Research suggests that domestication had taken place by approximately 6,000 years ago. It is supposed that the horse was first used by a tribe of Indo-European origin that lived in the steppes north of the chain of mountains adjacent to the Black and Caspian seas. Influenced by climate, food, and humans, the horse rapidly acquired its present form.
