    Bella is 13. The vet said the gray is just her age. 5 weeks in, her eyes look clearer and she found her ball in the grass again.

    The vet said $5,000 surgery or nothing for my 12 year old. I said no. A month in, the cataracts are clearing and he stopped bumping into the furniture. Did not expect that.

    Honestly thought it was a scam. Wasted so much money on drops and chews that did nothing. Almost gave up around week 2. Week 6 her cloudy eyes had cleared up and she ran to me at the door.

      • Lutein From the Marigold Flower

        Many eye supplements use synthetic lutein made in a lab. GRONOIR uses 100% pure lutein from the marigold flower, in a form your dog's eyes can absorb and use.

      • Vitamin E: Calms and Protects

        Vitamin E protects the lens. It keeps the lutein stable and shields the eye from daily wear, so the lens stays clear and healthy.

        • I Got My Dog Back

          I noticed her eyes getting cloudy and the vet said it’s just her age. She’d started hesitating at the stairs and couldn’t find her ball at dusk. We started GRONOIR and a few weeks later the cloudiness was clearing. Now her eyes are clear, she takes the stairs herself and finds her toys again. My daughter found this and I’m so glad she did.

        • Said no to surgery. By week 7 the cataracts had cleared

          The vet said surgery or nothing and I couldn’t put a 12 year old through that. I didn’t know what else to do until I found GRONOIR on Facebook. It’s 1 spray, done in seconds. By week 7 the cataracts had cleared and he catches his toys mid air again. I’m so glad I didn’t give up on him.

        • No More Drop Battles

          It used to be 3 eye drops a day, her fighting me every time, me doing it alone with a squirming dog who hated it. GRONOIR is one spray and she doesn't even flinch. Within a few weeks the cloudy film over her eyes had cleared. She tracks her ball across the room again. After everything else that did nothing, this is what worked.

          Sue D.

        • My Vet Asked What I'd Changed

          My vet said the cloudy eyes were just her age, nothing could be done. I couldn't just leave it, so we tried GRONOIR. Over a few weeks her eyes went from milky to clear. She's herself again. At the next check up my vet went quiet, looked closer, and asked what I'd been doing.

          Linda P.

        • She Found Her Water Bowl Again

          She'd started missing her water bowl and bumping into door frames. Her eyes had this milky film over them. The vet just told me to monitor it. We started GRONOIR instead. A few weeks in the cloudiness was lifting and now her eyes are clear. She moves around the house like she used to, no more bumping.

          Frequently Asked Questions

          Why will food drops, powders, capsules and chews never work?

          Because they all go the same way. Into the mouth, down to the stomach, and the lutein never finds its way to the eye. The problem is in the lens, not the stomach. GRONOIR is sprayed right at the eye and uses blink fusion technology. With every blink the lutein goes through the eyelid and straight to the lens, where the cloudiness sits. No stomach. No waiting.

          My vet said nothing can be done. Why this?

          Most vets have 3 answers for cloudiness in the eyes: “just old age,” “just monitor it,” or surgery. They learned them years ago, before the lutein link was known. When lutein runs low in the lens, the proteins clump together. That is the cloudiness. Not old age. GRONOIR puts the lutein back at the lens, the clumps spread out again and the lens clears up. No surgery. No waiting.

          My dog is 14. Is it too late?

          No. The spray works on the clumped proteins in the lens, no matter how long the eyes have been white/gray/blue. Most dogs in our survey were 11 or older. And with the 90 day money back guarantee, there is no risk in trying.

          Can I use it on a diabetic dog?

          Yes. The spray goes on the eye, there is nothing to swallow and no sugar. Just lutein and vitamin E.

          What if it doesn't work for my dog?

          Then you get your money back. Every order is covered by our 90 day money back guarantee. Just contact us and we'll refund you, no questions asked.

          The cloudiness in Bo's eyes kept getting worse. I had to do something. One spray and Bo is done. No wrestling. No fighting. I saw a difference in Bo's eyes in about 10 days. The haze started thinning out.

          I thought Duchess would run from the spray. He does not even flinch. Duchess found his ball in the grass without sniffing around for it.

          My neighbor pointed out the haze in Sophie's eyes. I had been trying not to think about it. I spent so much money on other products for Sophie's eyes. None of them did a thing. A woman at the dog park told me about this spray. Her dog's eyes cleared up so I tried it on Sophie. Sophie actually comes to me now when I pick up the bottle. No stress at all. Big difference after 2 months. The cloudiness is breaking up. Best purchase I made this year.

          The cloudiness in Shadow's eyes kept getting worse. I had to do something. So much easier than drops. Shadow just sits there and it is over in a second. After about 4 weeks the cloudiness on Shadow started breaking apart. My only regret is not finding this sooner for Shadow.

          I could tell Coco was losing her sight. Her eyes were glazed over and she looked so confused. I was buying eye drops for Coco every month. None of them made a dent. Someone in a dog group recommended this for Coco. Coco actually comes to me now when I pick up the bottle. No stress at all. Coco's eyes have more life in them now. The haze is almost gone after about 8 weeks. Coco looks right at me again when I call her name. That was everything. Do not waste money on pet store drops. Get this for your dog like I did for Coco.

          I felt so guilty watching Jasper struggle to see. Like I should be doing something but did not know what. My sister sent me the link. Her dog had been using it so I figured I would try it on Jasper. I was worried Jasper would hate the spray but she barely notices it. The cloudiness on Jasper's eyes is fading. I can see the difference. Jasper is like a whole new dog after about close to 3 weeks. She started playing with her toys again. Five stars for what this did for Jasper.

          The vet wanted to do surgery on Gus but at 13 I was too worried about the risks. Pills, chews, drops for Gus. I tried them all. Not one cleared up a thing. I was ready to try one last thing for Gus. Glad this was it. Way easier than the drops I used to wrestle Gus for. Just one quick spray. Gus's eyes are so much brighter after close to a month. The cloudiness really faded. Gus can see treats on the floor again. That alone was worth it. Telling all my dog friends about this.

          The vet said Buster had cataracts and the only option was surgery. At 8 that was not happening. The chews I got for Buster at the pet store did nothing for the cloudiness. I found this after searching for anything that might help Buster's eyes. One spray and Buster is done. No wrestling. No fighting. The fog over Buster's eyes is lifting. Every day I see a little more of her real eyes. Buster stopped bumping into the coffee table. That was the first sign. Do not waste money on pet store drops. Get this for your dog like I did for Buster.

          Hank's left eye went cloudy first. The right one followed. She was bumping into everything. I had pretty much given up on Hank's eyes after all the pet store stuff failed. My sister sent me the link. Her dog had been using it so I figured I would try it on Hank. I spray it from a few inches away and Hank just looks at me like nothing happened. Hank's eyes are clearing up. The milky look is fading fast. I finally feel like I did something that actually worked for Hank.

          I took a photo of Benny and that is when I really saw how cloudy her eyes had gotten. Pills, chews, drops for Benny. I tried them all. Not one cleared up a thing. A friend whose dog had the same thing as Benny told me about this spray. No mess and no fight with Benny. She just sits there for the spray. Three weeks in and Benny's right eye is almost clear. The left one is getting there too. Benny caught a treat I tossed from across the room. She has not done that in forever. If you are on the fence just try it. The guarantee makes it risk free.

          I took a photo of Cricket and that is when I really saw how cloudy her eyes had gotten. The chews I got for Cricket at the pet store did nothing for the cloudiness. A friend whose dog had the same thing as Cricket told me about this spray. No mess and no fight with Cricket. She just sits there for the spray. Cricket's eyes look so much better now. Worth every penny. Cricket found her toy under the couch the other day. No way she could have done that before. I wish I had found this sooner for Cricket.

          I noticed a turning white look in Juno's eyes a while back. It just kept getting worse. I tried pet store eye drops on Juno for weeks. Nothing changed. I found GRONOIR and figured the 90 day guarantee meant I had nothing to lose with Juno. I was worried Juno would hate the spray but she barely notices it. The change in Juno is real. Her eyes went from totally cloudy to almost normal looking. My only regret is not finding this sooner for Juno.

I wish I had found this sooner for Pete.
