Need help choosing the right protection from the sun, insects, wind, and dust for your pony or horse with sensitive eyes? Follow the guide.

Comparison table of our UV protection masks for horses and ponies

Does your horse suffer from a condition such as uveitis, ulcer, keratitis, cataracts, conjunctivitis, headshaking, etc., and do you need to equip it with eye protection in addition to its veterinary treatment?
Is he starting to age, and are his eyes increasingly dirty or watery?
Does your horse have light-colored eyes or is it photosensitive, bothered by bright light?
He is genetically predisposed to eye diseases (Appaloosa, Haflinger, Comtois breeds, cream coat, etc.).
Do you simply prefer "prevention over cure"?

Size guide - Premium or Helios mask

Using a tape measure (or a piece of string that you will measure afterwards), measure around your horse's head as shown in the photo:

Mask size	Head circumference
XS - Shetland*	84 cm
S - Poney*	90 cm
M - Cob*	94 cm
L - Full*	100 cm
XL - XFull*	110 cm

If your horse's head measurement falls between two sizes, we recommend choosing the larger of the two.

Size guide - Equivizor masks (Lightweight, Arso, Convalescence models)

For these masks, the main measurement is the width of your horse's forehead. To do this, you need to add together three measurements:

Start at the outer corner of one eye and measure upwards at a slight angle to the middle of the forehead (measurement A).
continue along the front of your horse(measurement B),
Finish the measurement by directing the line slightly downward to the outer corner of the other eye (measurement C). This way, you will measure the widest part of your horse's forehead.

Add these 3 measurements (A+B+C) to obtain the size of your horse's forehead.

IMPORTANT: Do not measure directly from one eye to the other, as this will likely result in an inaccurate measurement.

XS - Shetland*	7.5–8.7 inches
