Vet-Reviewed 2025 Canada Guide: Top 5 Tear Stimulants and Eye Lubricants for Horses — Find the Right Option for Performance or Aging Equines
This category covers products that boost natural tear production and provide long-lasting lubrication for equine eyes, including hyaluronic acid gels, artificial tear formulations, and mucomimetic lubricants used to support dry eye, post-operative care, and daily comfort in performance and aging horses. Canadian buyers increasingly prefer preservative-free and long-wearing topical gels that reduce dosing frequency and minimize irritation in cold, dry climates, while performance riders and breeders look for veterinarian-compatible options that balance protection with ease of use and availability. These products appeal because they address common equine ocular needs—maintaining corneal moisture, mimicking tear-film components, and supporting healing—while fitting into stable routines and provincial supply chains.

Top Picks Summary
Vetericyn Plus Antimicrobial Eye Wash
Vetericyn Plus holds a top position for equine ocular care because its wound-cleansing antimicrobial formula helps reduce bacterial load without irritating delicate equine eyes, making it a strong first-line wash before lubricants or veterinary intervention. Compared with thicker lubricants on this list, its technical advantage is safe, frequent-use irrigation and infection control, and it is often more cost-effective for routine flushing than repeatedly replacing preservative-free drops.
Estimated$20 – $40
Systane Ultra Lubricant Eye Drops
Systane Ultra is included as a market-leading lubricant due to its advanced polymer blend that provides longer-lasting tear-film stabilization, which can reduce application frequency for horses prone to dry eye. Financially it is positioned as a premium human ophthalmic product repurposed for equine use, offering superior comfort and residence time compared with basic saline washes but typically at a higher per-dose cost than generic or vet-formulated gels.
Remend Eye Lubricating Drops
Remend Eye Lubricating Drops are recognized for delivering a straightforward, economical lubricant option for equine tear supplementation and maintenance therapy, making them a good value choice for owners managing chronic mild dryness. Technically they trade some of the long-residence benefits of gel formulations for easier spreading and lower cost per application versus thicker products like Optixcare or veterinary gels, so they fit a budget-conscious maintenance niche on this list.

I-Drop Vet Plus Lubricating Eye Drops
I-Drop Vet Plus earns a leading role for horses because it is a veterinary-focused, preservative-free formulation designed specifically for animals, offering a thicker, more protective tear substitute that is well suited to corneal compromise. Compared with multi-use human drops, its technical advantage is reduced risk of preservative-induced toxicity and better suitability for frequent or long-term therapeutic use, though it can carry a higher price per vial consistent with single-use veterinary products.

Optixcare Eye Health (with Hyaluronic Acid)
Optixcare Eye Lube Plus is a market leader for equine lubrication when long-lasting ocular protection is needed, as its viscous gel formulation adheres well to the cornea and reduces reapplication during riding or turnout. Financially and practically it often represents a cost-effective compromise between frequent drops and custom veterinary preparations, offering extended retention similar to prescription gels but usually available over the counter.
Estimated$25 – $60
What the Research Says About Tear Stimulants and Eye Lubricants
Veterinary ophthalmology research supports the use of targeted lubricants and secretagogue therapies to improve tear-film stability, protect the cornea, and reduce clinical signs of dry eye. Studies and clinical case series indicate that formulations containing high-molecular-weight hyaluronic acid or mucomimetic agents can retain moisture on the ocular surface, while preservative-free preparations reduce epithelial irritation when used frequently. Controlled and observational veterinary reports also show that long-acting gels and ointments improve comfort and reduce the need for hourly dosing in field settings, although prescription tear stimulants and immunomodulators should be used under veterinary guidance for chronic or severe cases.
Hyaluronic acid binds and retains water on the corneal surface, increasing tear-film stability and improving comfort in both acute and chronic dry eye presentations.
Mucomimetic ingredients help recreate the mucin layer of the tear film, improving spread and adherence of lubricants between blinks.
Preservative-free formulations are associated with lower rates of epithelial irritation and are preferred for frequent application or sensitive eyes.
Long-acting topical gels and ointments reduce dosing frequency, which is especially useful for performance horses and owners managing multiple animals.
Veterinary studies and clinical case series report improved corneal healing and reduced signs of ocular surface disease when lubricants are used as directed alongside veterinary care.
Tear stimulants and secretagogue therapies can increase natural tear production in some chronic cases, but they require a veterinarian’s diagnosis and monitoring.
