Blinking or Eyes Closing
Look at the signal, then look at the whole horse and the situation around it.
NOTICE
The horse blinks, partly closes the eyes, or keeps them closed for a period of time.
Notice whether you're seeing an ordinary blink, quiet resting, or a clear change from what the horse was doing before.
WHAT IT MAY TELL YOU
Blinking and eye closure are part of normal eye care and can also appear with rest, drowsiness, and shifts in attention.
Horses may blink less when they are concentrating closely on something.
DON'T ASSUME
Blinking or closed eyes don't automatically mean the horse is relaxed, trusting, stressed, or feeling one particular emotion.
Instead, ask: “What is the horse paying attention to, and does the eye itself look comfortable?”
LOOK AGAIN
Is the horse dozing with a soft body, or tightly closing one eye? Does blinking change when attention shifts?
Look for tearing, swelling, rubbing, discharge, light sensitivity, or other signs that the eye may be uncomfortable.
SAFETY
If one eye is being held closed—especially with tearing, swelling, cloudiness, discharge, rubbing, or obvious discomfort—treat it as a possible eye-health problem rather than a body-language clue alone.

What research suggests
Recent research found that spontaneous blink rate in horses decreases as attention becomes more selective. Horses also have individual baseline blink rates.
What that does not mean
There is no single “normal blink number” that can be used to identify an emotional state. Eye closure can also reflect rest or eye discomfort, so context and eye health matter.
