UV blocking, or more accurately, UV reducing, masks are widely available for horses. There are a surprisingly large number of reasons you might want to use one, including Equine Recurrent Uveitis, eye conditions such as cataracts, corneal ulcers, conjunctivitis, eyelid cancer or ocular tumours, photosensitivity, sunburn protection, headshaking, and post-injury or post-surgical recovery.
There are many UV “blocking” masks on the market, ranging from approximately £30 to £300. But do the manufacturers’ claims match the actual UV blocking performance, and are the more expensive masks better?
These are the masks we tested…..

| Guardian Original Horse Mask |
| Harrison Howard Supreme Fly Mask |
| Kensington Uviator |
| Le Mieux Armour Shield Fly Protector Full Mask |
| Premier Buster Mask Standard+ |
| Premier Equine Comfort Tech Lycra Fly Mask XTRA |
| Shires Fly Mask Fine Mesh |
| Shires Fly Mask Sun Shade |
| Woof Wear UV Fly Mask without ears |
Whilst this testing was originally funded by AskAnimalWeb members, occasionally, in the interests of welfare, we release results publicly. We did this with our survey on grazing muzzles.
In our testing, whilst five different brands of UV masks claimed greater than 90% UV blocking, and in two cases claimed 100%, only one mask actually blocked 90% UV. Two of the masks claiming to block 100% only blocked 60–70% UV.
You can check how well your UV mask stacks up against the manufacturer’s claims here, or check out which ones we recommend if you are looking to buy one.

Equine Recurrent Uveitis (ERU or Moon Blindness)
Horses with ERU, an inflammatory eye condition, benefit significantly from UV masks. UV exposure can exacerbate symptoms such as eye pain, swelling, and cloudiness. Masks with high UV protection (90–95%) should reduce flare-ups and aid in managing this chronic condition by shielding the eyes from sunlight.
Photosensitivity
Horses with light-coloured coats, pink skin, or pale eyes (e.g., blue-eyed horses or those with white face markings) are prone to photosensitivity. UV masks protect against sunburn and reduce the risk of UV-related skin damage or photosensitisation, which can cause painful skin reactions.
Eye Conditions
Conditions such as cataracts, corneal ulcers, and conjunctivitis require protection from UV rays, dust, and wind, which can worsen symptoms or delay healing. UV masks with high protection ratings (>90%) are recommended by veterinarians for these cases to prevent further irritation or damage.
Sunburn Prevention
Horses with pink or unpigmented skin, especially around the muzzle, eyes, or white face markings, are at risk of sunburn, which can lead to discomfort or increase the risk of squamous cell carcinoma. UV masks, particularly those with nose coverage, provide a physical barrier to block harmful rays.
Headshaking Syndrome
Horses exhibiting headshaking, often triggered by sunlight, wind, and/or environmental irritants like dust or pollen, may benefit from UV masks. These masks reduce exposure to triggers, helping to alleviate symptoms and improve comfort during turnout or riding. If you have a horse that headshakes, especially in strong sunlight, then a good UV mask is worth trying.
Eye Cancer or Tumours
Horses with a history of eyelid cancer or other ocular tumours (e.g., squamous cell carcinoma) require UV protection to prevent recurrence or worsening of the condition. UV masks act as a preventative measure by minimising sun exposure to vulnerable areas.
Insect Protection
While not exclusively for UV protection, many UV masks also shield against flies, mosquitoes, and gnats, which can irritate eyes and transmit diseases. This is particularly beneficial for horses with sensitive eyes or allergies to insect bites, reducing stress and the risk of infections.
High UV Environments
In regions with intense sunlight, such as southern USA, the Gulf States, many regions of Australia, and South Africa, for example, or during seasons with high UV exposure (e.g., summer or areas with reflective snow), UV masks can protect horses from excessive UV radiation, even if they don’t have specific medical conditions.
Post-Surgical or Injury Recovery
After eye surgeries or injuries, UV masks provide a protective barrier to prevent irritation from sunlight, dust, or debris, promoting healing and reducing the risk of complications such as infections or ulcers.
General Comfort and Stress Reduction
Horses that squint, show discomfort in bright sunlight, or toss their heads due to UV exposure can benefit from UV masks. These masks improve overall comfort, reduce stress, and allow horses to graze or move without visual or physical discomfort.
