These masks are primarily designed to prevent your horse from rubbing its eyes following an operation, injury, ulcer, etc. The transparent version, made from 100% UV-resistant PVC, makes it easier to check the eye (a fly mask can be added if required).
Metal shell masks allow for good air circulation while protecting against insects and friction during the healing process. You can also find the Equivet mask, used by most equine clinics post-operatively or to keep a painful eye in the dark during an uveitis flare-up.
