The OcluVet formulas

Every OcluVet formula is built the same way: named ingredients at stated concentrations, with independent research behind them. The drops deliver antioxidants directly to the eye. Vision Chews support eye health from the inside. Together, they're the foundation of a daily eye care routine for dogs and cats.

OcluVet eye drops formula

The primary antioxidant is N-acetyl-L-carnosine (NAC) at a 2% concentration. NAC is a stabilized form of the antioxidant carnosine. NAC is a stabilized derivative of the antioxidant carnosine. It is designed to resist premature breakdown and act as a precursor to carnosine in the eye. It helps provide antioxidant support to the eye. 

The lens of the eye is made of delicate proteins, and over a lifetime, those proteins are damaged by oxidation, the same chemical process that turns a cut apple brown. As damage accumulates, the lens loses clarity. Antioxidants are the body's counter to that process, and NAC is an antioxidant that can be delivered directly to the eye as a drop.

The research behind the drops

This independent study evaluates topical 2% NAC in supporting lens health.

University of Cambridge study

Williams and Munday, Department of Veterinary Medicine, University of Cambridge. 

In this 2006 study published in Veterinary Ophthalmology, 30 dogs of varying breeds and ages with lens changes ranging from early age-related haze to advanced opacity. The dogs were treated 3 times daily with topical 2% NAC. Lens clarity was assessed at 2, 4, and 8 weeks using ophthalmic examination, photography, and computerized image analysis.  Lens-opacity measurements decreased across all groups.  Owner assessments suggested improved visual capability in 80% of cases.

The supporting antioxidants

OcluVet drops contain six antioxidants in a sting-free, preservative-free formula: 

  1. N-acetyl-L-carnosine (NAC). An antioxidant that supports lens clarity.
  2. L-carnosine. An antioxidant that protects the delicate proteins inside the lens.
  3. L-glutathione. The lens's own primary antioxidant. The formula supplements what the eye already uses to defend itself.
  4. L-cysteine ascorbate. A stabilized vitamin C compound that provides nutrients the eye needs to recycle its own glutathione back to active form.
  5. Riboflavin. Vitamin B2, a cofactor in the same recycling cycle.
  6. Taurine. An amino acid concentrated in healthy ocular tissue, where it helps stabilize cell membranes.

The antioxidants in the OcluVet formula work together to neutralize oxidation directly or help support its natural antioxidant defenses.

Our drops are preservative-free

Preservatives are a common source of stinging in ophthalmic solutions, and a drop that stings is a drop that gets skipped. The formula is preservative-free so a daily routine stays comfortable for your pet.

The Vision Chews formula

The chews take a different route to supporting vision health. Vision Chews provide systemic support, making them a great addition to your pet’s daily eye care protocol. 

The source ingredient is QRILL PETâ„¢ Antarctic krill from Aker BioMarine, which supports eye health through:

Astaxanthin

The carotenoid antioxidant that makes krill red. In dogs, astaxanthin functions as a systemic antioxidant, the same job the drops' ingredients do at the lens, performed from the inside.

DHA

An omega-3 fatty acid that is a structural lipid of the retina: not just support for the eye, but part of what the eye is built from.

Responsibly sourced

The krill in Vision Chews is harvested under Marine Stewardship Council certification, in a fishery managed by CCAMLR, the international commission governing Antarctic marine life, with Aker BioMarine operating voluntary buffer zones around penguin colonies.The drops are manufactured in the USA with domestic and imported ingredients, in Fort Washington, Pennsylvania.

How to read a pet eye supplement label

When you’re looking at pet eye supplements, the label can tell you how much of the active ingredients your pet will get.

  1. The active ingredient and its concentration. Not "proprietary antioxidant blend": the named compound and the percentage. OcluVet contains a 2% N-acetyl-L-carnosine.
  2. Preservatives. A preserved drop and a preservative-free drop are different daily experiences for the pet receiving them.
  3. The route. Most eye supplements are oral only. A drop applied directly to the eye reaches ocular tissue without a detour through digestion, while an oral supplement supports systemically.

For veterinary professionals

OcluVet was dispensed exclusively through veterinary clinics for its first decade, and the protocol is built around your recheck: loading for 6 to 8 weeks, evaluation, then step-down to maintenance. Study documentation, dispensing protocols, and partner terms are on the professional page.
