More Eye White Showing
Look at the signal, then look at the whole horse and the situation around it.
NOTICE
More of the white part of the eye—the sclera—is visible than is usual for that horse.
This may appear above, below, or around the colored part of the eye.
WHAT IT MAY TELL YOU
More visible eye white can occur when the horse changes eye position, widens the eye, or strongly looks toward something.
It may accompany increased attention or arousal, but the meaning depends on the horse and the situation.
DON'T ASSUME
More eye white does not automatically mean:
- “My horse is terrified.”
- “My horse is panicking.”
- “My horse is angry.”
Some horses naturally show more sclera than others, so change from the individual horse’s baseline matters.
LOOK AGAIN
Ask what the horse is looking at. Compare both eyes if you can. Are the eyes also wider than usual? Is the head or neck raised? Is the body tense? Does the visible white disappear when the horse changes focus?

What research shows
EquiFACS codes increased visible sclera separately from increased eye opening. More eye white can result from eyeball movement as well as changes in eyelid opening.
What it does not tell us
Visible sclera alone cannot identify fear or any other specific emotion, and normal baseline visibility differs between horses.
