Our kids at home snack on Doctor BY Eyes. That's how tasty it must be~~~ If I say I’d be worried without the effects, can you understand? ^^

Because of tear stains, I changed my pet’s feed and tried using tear wipes, but nothing really worked.
Try feeding it for just one month :) All dogs in the world don’t lose their appearance because of tear stains, so I'm writing this.
- jung******

This is my dog’s favorite supplement! Since he was a puppy, I’ve consistently given it twice daily for 4 years.
It’s probably because of its good efficacy... He’s excited every time he eats it haha.
Thanks to it, his tear stains are gone and he looks like a neat and tidy dog now.
- sker****

The tear stains completely disappeared!!
I was half doubtful at first, but almost a month has passed and there’s no trace of it at all!!
I strongly recommend it haha.
- anse*****

This is a product I’ve been feeding my dog for a long time, and I’m repurchasing it to keep feeding it!!
The tear volume has definitely decreased, and since my dog is a bit older, there were parts where eye health was a concern,
but it seems the eyes are clearer than when not feeding it.
Feels like it’s effective so I plan to keep feeding it haha.

Core Organ for Eye Health: The Liver

When the liver's detoxification function declines, problems arise in detoxification and metabolism, making it difficult to supply oxygen and nutrients to the eyes. As aging progresses, the liver's function decreases, leading to eye aging and darkening of the tear fluids.

'Doctor Buy Eyes' Frequently Asked Questions (FAQ)

Q1. Should I give it before or after meals? Can it be given all at once?

A1. It can be given before or after meals without issue. When given with feed or after a meal, absorption is stable without irritation. The recommended daily amount can be given all at once, or split between morning and evening. The most important thing is to provide it consistently every day.

Q2. When should I start giving eye and tear nutrition supplements?

A2. It can be given starting from 3 months after birth. Starting early as a preventive measure is helpful.

Q3. If temporary diarrhea or loss of appetite occurs, should I stop immediately?

A3. 'Doctor Buy Eyes' contains prebiotics like fructooligosaccharides, which are food for beneficial bacteria, so sensitive pets may occasionally have loose stools. At such times, increase water intake by feeding more than usual. If there is suspicion of temporary stomach or intestinal irritation from eating too quickly, reduce the daily dose by half, divide it over two days, and give it slowly. Once symptoms subside, most pets recover when returning to the normal amount.

Q4. Can it be given to pets with meat allergies?

A4. 'Doctor Buy Eyes' does not contain meat proteins, so it can be given even to pets with meat allergies without burden.

Q5. Can it be given concurrently with prescribed medications (for dry eye, allergies, etc.)?

A5. Most eye drop medications and ophthalmic prescriptions can be used simultaneously without problems, but if steroids, antibiotics, or eye drops are taken long term, liver metabolism burden may increase. Please consult your attending veterinarian and confirm medication compatibility.

Q6. Are there other 'Doctor Buy' products that additionally help eye health?

A6. Using 'Doctor Buy Omega-3 [2.0]' together can provide EPA and DHA which help support eye health.

Q7. Can cats also consume this product?
