Homemade Eye Wash For Horses

Last Updated on March 11, 2022

If your horse needs his eyes flushing regularly, then store-bought eye wash can seem quite expensive. But is homemade eye wash for horses a good idea, and how do you make it? Let’s find out!

What Is Eye Wash?

Eye wash is a liquid used to rinse the eyeball of a horse. The eyeball is a very sensitive part of the horse and can be easily damaged by chemicals and toxins. This means that your eye wash needs to be gentle and only contain chemicals that are safe to use in the eye.

In fact, most eye washes are very similar to the natural eye wash produced by the horse – tears! Although we think of tears as something produced when we cry, they actually have a really important function. Tears are produced continually by the eye in very small quantities, to keep the surface of the eye moist and rinse away debris.

What Is Eye Wash


The tears produced by the eye contain the perfect balance of water, electrolytes (salts), fatty oils, and proteins. Commercial eye wash solutions aim to replicate this formula, creating a fluid that can rinse the eyeball without causing harm or irritation to the surface of the eye.

Why Do Horses Need Their Eyes Flushing?

The most common reason to flush a horse’s eye is to remove dirt or debris. Most commonly, dirt is removed by the horse through a combination of tear production and blinking, but sometimes we need to give them a helping hand.

If your horse’s eyes are watering a lot, then it is likely that this is in response to an irritant such as dust or flies. Most tears drain away through a tube called the nasolacrimal duct, running from the corner of the eye down to the inner nostril. But when a lot of tears are produced, they spill over and run down the face.

In this situation, you might think that flushing your horse’s eye is a good idea. But before you do, take a good look at the eye itself. If you see anything to make you suspect that there might be a problem with the eye, seek veterinary advice immediately. The eye of a horse is very sensitive and eye problems are considered to be a medical emergency.

If you cannot see any other symptoms of eye problems, then try giving your horse’s eye a gentle flush to see if it resolves the problem.

Is Homemade Eye Wash A Good Idea?

For occasional eye flushing, most people opt for a store-bought eye wash solution. This can be stored in the first aid kit until needed, and you can feel reassured that it is perfectly suitable for flushing a horses eye.

But if you need to flush your horses eyes frequently, you might be considering making a homemade eye wash for horses. This is only really worth doing if you regularly need large quantities of eye wash, as it does not last as long as a commercial eye wash. This is because commercial eye wash is completely sterile, whereas our homemade version is at a higher risk of contamination.

When it comes to horses’ eyes, we should only use eye wash that is sterile and free from potential sources of infection. Even water can contain bacteria and must be sterilized before using it as an eye wash. Let’s find out how to turn a few simple ingredients into a homemade eye wash for horses!

How To Make Homemade Eye Wash For Horses

A homemade eye wash for horses is a saline solution, made with salt and water. This should be at the exact concentration to mimic the electrolyte concentration in tears.

To do this, take two cups of water and boil them for 15 minutes – this will kill any pathogens in the water. Add 1 teaspoon of table salt, and stir well until the salt is dissolved.

Put the liquid into a clean, airtight container. When it is cooled you can use it to flush your horses’ eyes.

The homemade eye wash for horses can be stored in the refrigerator for up to 24 hours. After this, it is no longer safe to use and must be discarded.

This is a useful recipe to know if you have an emergency and have run out of eye wash, or need large quantities of eye wash to get through a period of dry, dusty weather. However, it is always a good idea to have some store-bought eye wash in your first aid kit as well.


So, as we have learned, homemade eye wash for horses can be made using salt and water, but the recipe must be followed carefully. Horses’ eyes do not need routine flushing unless your horse is kept in a very dusty environment. You should only wash your horses’ eyes if instructed to by your veterinarian, and only use recommended flushing liquids.
