EQUIVIZOR eye protection
Instructions for use

General notes:

The mask protects your horse reliably, if the correct conditions are also given:

  • remove or block access to protruding resistances on which the horse can “hook” the mask and then pull it off the head by force ; this also applies to fences (barbed wire!!), door handles etc.. The closure clips are “predetermined breaking points” which must break if the horse gets caught somewhere with the mask ! Replacement closures (clips) can be found in our store under “Accessories”.
  • the mask is intended and suitable for 24/7 use – even in open stables and with other horses, as is the case with most of our customer horses. However, occasionally other horses may be provoked to play with the mask and bite or tear it off your horse’s head (CAUTION: do not let the halter hang long, this “tempts”, see Figure 6-9 below). In extreme cases, prevent access to other horses and block contact with the horse in the neighboring stall – otherwise it could succeed in tearing the mask off your horse’s head.
  • alleviate pain of the horse, if possible. Because in severe pain, the horse will recklessly try to get to his eye
  • sand/dirt can penetrate through the important ventilation holes of the mask. The horse should therefore ideally be kept in an environment as free of sand/dust as possible or not be able to roll around in it
  • the higher the temperature, the more pliable the material. At temperatures below zero, it stiffens accordingly, but remains flexible even at -25 degrees. However, ATTENTION: Cracks can occur due to impacts at sub-zero temperatures ! These are NOT due to material defects or deficiencies. They can be repaired with special glue (pdf).
  • the mask must have the correct size! NOTE: If your horse repeatedly drops the mask and the cause is not apparent, the mask can be attached to a stable halter (with string or similar) if necessary. Feel free to send us photos of your horse with mask (info@aniprotec.de) and call us to check the size.

The EQUIVIZOR eye protection mask fits correctly when

  • the right and left outer edge of the mask ends almost under the ears (= correct mask size) ; thus there is enough space between the corner of the eye and the edge of the mask (see picture 1)
  • the neck strap forms an almost continuous “line” with the rear throat strap (see picture 2). If necessary, remove the connecting piece between the two throat straps.
  • the mask is clearly wider than the head when viewed from the front; the triangles therefore protrude next to it (Fig. 3)
  • the “triangles” sit exactly at eye level (Fig. 4, green dashed)
  • the lower edge of the mask ends almost in the middle of the horse’s head/nose bridge (picture 3 and picture 4)
  • the mask rests all around

Correct creation

  • Put on the mask so that the “row of holes” is at the top. The upper edge of the mask ends at the top just before the ears. The mask wraps around the face
  • Then close the strap behind the ears. It should fit snugly, but never be pulled too tight. You will have to readjust it later.
  • Then close the two straps under the chin. Make sure that the latches are tight. You will – and must ! – open (or break) only if force is applied to them, e.g. if the horse gets stuck somewhere.
  • If the straps need to be adjusted, TAKE THE MASK OFF AGAIN, OPEN THE CLIPS, and then adjust them. Repeat this process until the mask fits well
  • Then watch the horse when it eats. The mask should fit snugly but not be so tight that it interferes with the horse’s eating or even rubs against the skin (Figure 5). When removing the eye protection, no imprint of the mask must be visible on the face – otherwise it is too tight !
  • If necessary, remove the “bridge” between the two throat straps and place the inner strap behind the gaiters. Do not pull too tight !

Once the mask has been fitted, we strongly recommend CUTTING OFF THE TOO LONG ENDS OF THE RIEMS (Fig. 6). Seal the ends with wax, glue or similar. Pull the end of the strap through the clip again so that it is now on the inside of the face (Fig. 6-9) :

We advise against knotting or looping the ends under the straps, because

  • other horses could pull on them and so the mask could be torn off the head by force
  • the horse could get caught somewhere with the long straps, which would possibly lead to the opening/breaking of the fasteners

Replacement closures (clips) can be found in our store under “Accessories”.

CHECK THE CORRECT SEAT at regular intervals!


A horse whose eyes are sore or injured, itchy or stinging, will try to relieve this irritation by rubbing them more or less. The EQUIVIZOR Eye Protection Mask is designed to protect the horse’s eyes even when they are strained by rubbing, chafing and prodding the horse:

  • The material of the mask MUST be soft on the one hand (so that the horse does not injure itself or others !), but on the other hand so resistant that it does not tear or collapse on the eye. This is ensured by the thick but soft PVC and the design with the outer corners. However, the PVC will be scratched by the stress – this is unavoidable. Otherwise, each of these scratches would end up in the horse’s face or eye – with dire consequences. Scratching the mask therefore does not represent a reduction in value.
  • The transverse center seam on the PVC of the mask can become loose due to chafing. This has no limiting effect on the function of the mask. This seam is needed during production to hold the two edges in position while the composite adhesive cures. After that, it no longer has any function. It is the strong composite adhesive that permanently closes the seam
  • The double stitched seam of the border can also open up at individual stitches of one of the double seams due to strong rubbing. The stitches are set in such a way that “pricking up” is made very difficult. The second seam is usually not affected and keeps the wool padding stable. Nevertheless, we recommend that you check the mask regularly and, if necessary, have it resewn by a saddlery in good time.
  • The soft, woolen underpadding of the edge of the mask is designed to help prevent skin injuries. A prerequisite is that the mask was not tightened too tightly. Another that the horse does not “rub” extensively. However, if the latter is to be expected due to the medical situation and there is a risk of pressure sores or skin abrasions, we recommend the use of a skin protection product from the outset. These are available on the Internet or the pharmacy. They are applied to the facial fur, where they form a thin, protective film for up to 72 hours. Here is a product example from company ConvaTec Sensi-Care skin protection wipes. Similar products are equally suitable.
  • Especially for horses with uveitis, eye protection plays a major role: if the eye is injured by scratching, a corneal ulcer often forms. Uveitis then cannot be effectively treated until the ulcer is healed !
  • Horses suffering from uveitis (periodic ophthalmitis, moon blindness), for example, often experience severe pain, especially during episodes. They will inevitably try to reach the eyes and will be prone to severe mask rubbing. Timely/preventive use of skin protection products is strongly recommended. Clients told us that in horses with uveitis, sudden chafing under the mask indicated that a new episode was imminent. They took this as an opportunity to have the horse treated at an early stage
  • An additional, removable fleece pad set is not included with the mask (nose guard plus halter pad) and can be ordered in our store under the heading “Accessories”. It protects the bridge of the nose in the event of particularly violent stress caused by rubbing. The cushion set is washable. For special securing of the mask in case of severe pain/itching, it may be useful to additionally attach it to the halter

If the horse has already contracted corresponding sores on the face due to extensive rubbing, additional medical padding is recommended, which will also support the healing of the sore area and at the same time allow the mask to continue to be worn. Foam dressings are suitable for this purpose.

Here we mention as an example such a product of the company Mölnlycke, the Mepilex absorbent foam dressing, which is available in pharmacies. It is available in different sizes and can be cut to size as needed:

Another way to protect the horse’s face from sores is to use a head and neck chest protector, such as those available at specialty stores:

Care of the mask

  • The usual evaporation of horse skin causes the mask to acquire a fine, greasy film on the inside. Therefore, clean the mask regularly with warm rinse water. The fat solvent in the rinsing agent helps to make the mask clean and clear again.
  • NEVER allow the mask to soak in a cleaning liquid. The PVC will otherwise take on the color of the liquid and may also become blind!
  • as a cleaner, we can only recommend one product that we have tested: FC2 Foam Cleaner is a spray-on foam cleaner specifically designed for PVC. You can find the product in our store under “Accessories”.
  • Rub the mask dry with a soft, lint-free cloth; fine microfiber cloths are suitable for this purpose
  • Make sure that the black wool padding on the edge is well rinsed. Soap residues could otherwise damage the eyes of the horse

Since it protects the eyes, the mask will inevitably scratch – how much depends on how the horse handles it. Please keep in mind that this is not a piece of clothing or a decorative item – but a protective product comparable to a motorcycle helmet. This too will not look nice after an accident and will have defects because it has kept out damage. Better that way, than if the defects developed on the horse’s eye!

Detailed instructions for use can also be found in the appendix of the product presentation.


Here we describe step by step the subsequent padding of the mask:

1. general designations

Cushion set_copy

2. padding retrofit

  • Place the mask on the face, with the open area facing you
  • Align the pad with the Velcro seam facing forward toward you
  • The Velcro closure and the two halter loops are visible/top
  • Now pull the front gaiter through the right loop of the pad …
  • and the corresponding closure clip of the gaiter holster at the other end of the mask edge through the other/second loop of the padding
  • The cushion is now under the edge of the mask, the cushion seam with Velcro is outside the mask (NOT inside!)
  • remove the mask halter latch that is too small and replace it with the larger latch that comes with the cushion
  • pull through one of the holster pads
  • open the Velcro closure of the pad
  • pass the lower end of the pad Velcro through the large under ventilation hole of the mask
  • close the Velcro fastener of the cushion
  • Now pull the halter pad with bar over the front gaiter halter
  • pull the clip closure of the mask through the left loop of the pad. The cushion now completely hugs the edge of the mask
  • now pull the second halter pad over the rear gaiter halter
  • pull the halter and pad through the other loop of the bolt
  • pull the third halter pad over the neck halter
