Most people first notice horse blinders on a carriage horse downtown or a racehorse in the post parade. They’re the leather or plastic cups beside the eyes, and they look like they’d keep a horse from seeing much of anything. They don’t, but they do change what a horse pays attention to.
Here’s what blinders are, why a horse’s eyesight makes them useful, how they’re used on driving horses and racehorses, and when a horse is better off without them.

What Are Horse Blinders?
Horse blinders are pieces of tack that limit a horse’s peripheral vision, mainly by blocking part of what he sees to the sides. In the U.S., people say blinders and blinkers interchangeably, though racing people mostly say blinkers. You’ll also hear about winkers, which are related headgear that restricts less of the horse’s view.
They come in two basic forms. On a driving bridle, the blinders are leather pieces attached to the cheekpieces. In racing, blinkers are usually built into a cloth hood that goes over the horse’s head under the bridle, with a plastic cup beside each eye.
Why Horses Wear Blinders: How a Horse Sees
A horse’s eyes sit on the sides of his head, giving him a wide view of his surroundings. Each eye covers an arc of about 200 to 210 degrees, according to Iowa State University Extension. The binocular field, where both eyes see the same area, is much narrower, about 65 degrees, according to Cornell’s College of Veterinary Medicine. Most of what a horse sees comes from one eye at a time.
That wide view helped horses survive as prey animals. Horses are especially sensitive to movement, and sudden activity off to the side can distract or startle them. They still have blind spots directly behind them and close in front of their faces.
Blinders don’t make a horse blind. They narrow how much of that side movement reaches him, so a car pulling up beside a carriage or a horse coming up on the outside in a race is less likely to grab his attention.
Blinders on Driving and Carriage Horses
You see blinders on many carriage, wagon, and harness horses. A driving horse works in traffic, crowds, and noise, and a horse that spooks in harness can hurt himself, the driver, and anyone nearby.
Blinders limit the movement a driving horse sees alongside him. With traffic, pedestrians, and activity on either side, that narrower view can help a horse stay focused on the road ahead and the driver’s cues instead of reacting to everything moving around him.
Horse Racing Blinders
Horse racing blinkers serve the same basic purpose. They limit what a horse sees to the sides, which can help him concentrate on running instead of the crowd or the other horses. Trainers may try them on a horse that loafs, looks around, hesitates at the gate, or drifts when another horse comes alongside.
Racing blinkers come in several cup styles, from full cups that block most side vision to smaller cups that block less. A visor has a slit or hole in the cup so the horse can see a little to the side or behind, and fleece winkers on the cheekpieces are a milder option that mainly limits rear vision.
For a closer look at their use on the track, here’s why racehorses wear blinkers and the different cup styles trainers use. For more on results, see whether blinkers improve performance.
Do All Horses Need Blinders?
Not every horse benefits from having part of his view blocked. The question is whether the equipment suits that horse and the work he’s doing. Some horses get more nervous when they can’t see what’s around them, and if a horse gets more anxious, resists the bridle, or starts acting up after blinders go on, the style may be too restrictive or he may not need them at all.
They also won’t fix a training problem, pain, or a horse that’s scared for a reason. If a horse is spooking or acting out, find out why first. Blinders can help a horse focus, but they shouldn’t be used to cover up a problem that needs to be fixed.
Fit matters, too. Check that the cups sit beside the eyes without touching them, that the edges are smooth, and that nothing rubs. Have an experienced trainer or driving instructor check the fit, and introduce new headgear in a controlled setting before asking a horse to wear it somewhere busy.
Horse Blinders FAQs
What does it mean when a person wears blinders?
Having blinders on means focusing narrowly on one thing and missing other information or viewpoints. The expression comes from the way horse blinders restrict a horse’s view.
Can horses see with blinders on?
Yes. A horse can still see what’s in front of him with properly fitted blinders. The cups restrict some of his side vision, but they don’t cover the eyes. How much side vision is left depends on the style and size of the cups.
Do blinders hurt horses?
Properly fitted blinders shouldn’t touch the eyes. A poor fit can rub, and some horses are uncomfortable with the restricted view.
Used on the right horse, blinders are a simple piece of tack that does one job well: helping him concentrate on his work. What matters is whether he pays better attention without becoming more anxious.
