The GLO® Factor patented blend
Your pet’s eyes work hard. Antioxidants help neutralize free radicals, and Ocu-GLO® was formulated by veterinary ophthalmologists to support the cornea, lens and retina.
Grape Seed Extract
A secondary photoprotectant from the seed, not the skin. Rich in proanthocyanidins, one of the strongest free radical scavengers, supporting the cornea, lens and retina.
Lutein
A primary photoprotectant carotenoid antioxidant that filters blue light — a component of visible light from the sun that can be damaging to the delicate structures of the retina.
Omega-3 Fatty Acids
DHA and EPA incorporate into cell membranes and stabilize phospholipid bilayers, supporting corneal and retinal cells against damage from sunlight.
Sale questions, answered
How do I get the 25% subscriber price?
Choose “Subscribe & Save” on any product page and the 25% applies at checkout. New subscribers get 25% off their first order, then 5% off every order after. Already subscribed? Your renewal or “ship now” order placed between Nov 16 and Nov 30 gets 25% automatically — no code needed, and your usual 5% resumes afterwards.
Can I combine the 20% and the 25%?
No. One-time items get 20% and subscription items get 25%, so you always land on the better of the two. There is nothing to stack and nothing to miss.
How does the $9 second product work?
Add any Ocu-GLO® pet product to your cart, then add one eligible supplement — SHaNa Vet® 45ct, Imuno-2865® Vet 45ct, Serenin Vet®, Joint Guard Vet®, Digestin Vet or Artichoke & Milk Thistle. The $9 price applies at checkout. One add-on per order. 500ct bulk bottles are not included.
I use my own discount code. Will it still work?
Our sale pricing applies automatically, and only one product discount applies per item. If you have a code, it will replace the automatic sale discount rather than add to it — so use whichever gives you the lower price.
When does the sale end?
Everything ends Nov 30 at 11:59pm Pacific. The $39 Ocu-GLO® Human subscription price is the exception — it holds for subscribers through Dec 31, 2027.
Is shipping free?
Yes on US one-time orders of $49 or more during the sale. Subscriptions already ship free at $35 or more.
