Beyond Taurine and Lutein: Herbal Ingredients That Protect Your Furry Friend's Vision
Updated: Oct 11
Research shows that less than 20% of eye diseases in dogs and cats are caused by aging, meaning these conditions are no longer exclusive to senior pets. Therefore, whether your furry friend is young or old, it is crucial to pay extra attention to eye care!
Often called the "windows to the soul," the eyes are among the organs most prone to problems in our furry companions—yet these issues are also frequently overlooked.
The majority of cataract cases in dogs and cats are congenital or hereditary, often manifesting before the animal turns six.
Certain breeds are particularly predisposed, such as Maltese, Red Poodles, Beagles, Shih Tzus, Dachshunds, Golden Retrievers, Labradors, and Border Collies. Less than 20% of cases are caused by aging or complications from other diseases (such as diabetes).
Because eye conditions often develop slowly and progressively, a lack of regular observation means that by the time abnormalities are noticed, it may already be too late.
How can you spot the signs of eye discomfort in your pet?
Since pets cannot speak to express physical discomfort, detecting these issues relies entirely on the attentive observation of their owners.
1. Excessive, persistent tearing
Tears serve to keep the cornea moist and nourished, and they also help cleanse the eyeball if a foreign object enters the eye. If you notice your pet tearing up constantly under normal circumstances, it indicates an underlying eye problem.
2. Frequent rubbing or scratching of the eyes
If you observe your pet frequently rubbing its eyes against walls or constantly trying to scratch them with its paws, it may be a sign of itching, pain, or declining vision.
3. Accumulation of excessive eye discharge
When a pet's eyes are inflamed, tears can turn into a purulent discharge that fails to drain through the tear ducts; this eventually accumulates at the corners of the eyes as crusty discharge.
4. Eye redness
Redness in the corners of the eyes, the eyelids, or the whites of the eyes (sclera) may indicate conjunctivitis or keratitis; a visit to a veterinary clinic for further examination is essential.
5. Dry eye syndrome
Reduced or lost tear gland function leads to an insufficiency in the quantity or quality of tears, resulting in various ocular disorders. The most common cause is an autoimmune attack on the tear gland tissue; the resulting damage leads to inadequate tear production and eye dryness or functional decline. As the condition worsens over time, corneal keratinization, vascularization, and melanin deposition occur, potentially leading to blindness in severe cases.
Cultivate Proper Eye Care Habits to Effectively Protect Your Pet's Eyes
1. Routine checks and cleaning are essential.
Make it a daily habit to inspect your pet's eyes for any abnormalities (especially in breeds prone to eye issues and in senior pets over the age of seven). If you notice tears or discharge around the eyes, you can rinse them with sterile saline or wipe the area with a warm, damp towel, ensuring the eye area remains dry.
2. Regularly trim fur around the eyes.
Pets with long fur or deep facial folds are prone to eye irritation caused by overgrown hair; therefore, it is important to trim any excess fur around their eyes.
3. Supplement with eye-healthy nutrients.
Commonly known ingredients for eye health include taurine, lutein, beta-carotene, and omega-3 fatty acids; however, using Traditional Chinese Medicine (TCM) ingredients offers an excellent alternative approach.
In TCM, eye care is closely linked to the liver; visual function relies heavily on nourishment from liver blood and the smooth flow of liver qi. When the eyes lack this nourishment, issues such as dryness, redness, and increased discharge can occur. Thus, maintaining eye health requires an approach that starts from within.
While the use of TCM ingredients for human eye care is well-known, pet owners may not realize that the following ingredients can offer similar benefits for their pets' eye health:
Goji berries have a sweet, neutral nature and help promote blood circulation and metabolism. Rich in lutein, they nourish the kidneys, protect the liver, and benefit vision; they are particularly helpful for addressing issues such as presbyopia, cataracts, and dry eyes.
Chrysanthemum helps dispel wind-heat, soothe the liver, and brighten the eyes. It regulates excessive liver fire, protects eye health, and relieves eye fatigue.
Replenishing mucin (a type of glycoprotein formed by the combination of sugars and proteins) not only increases tear secretion but also improves the quality of tears; yam is one such food ingredient rich in mucin.
As previously mentioned, eye health is closely linked to liver health. Dendrobium also nourishes the kidneys, protects the liver, and benefits vision, offering varying degrees of relief and improvement for symptoms such as eye dryness and pain.
Dendrobium helps alleviate dryness throughout the body, including both the skin and the eyes. It can enhance eye comfort for individuals prone to dryness caused by prolonged eye strain or the use of contact lenses.
Cassia seeds help clear liver heat, brighten the eyes, and lubricate the intestines. They also lower intraocular pressure and boost the eyes' antioxidant capacity, thereby helping to prevent glaucoma.
For angle-closure glaucoma, they assist in lowering intraocular pressure and help clear inflammatory substances from the eye's anterior chamber.
【Poria】
Poria is sweet and neutral in nature; it promotes diuresis and harmonizes the spleen and stomach, effectively enhancing the body's ability to metabolize and transport fluids.
Traditional Chinese Medicine holds that the liver opens into the eyes; prolonged eye use can deplete heart and liver blood, impair vision, and damage the spleen and ocular muscles. Therefore, it is important to nourish the liver and kidneys, strengthen the spleen, and calm the heart. Poria, with its liver-protecting properties, is highly effective for individuals suffering from eye fatigue accompanied by restlessness and insomnia due to deficiency.
Prepared Rehmannia root is known for nourishing yin, replenishing blood, and boosting essence and marrow; it is often used in combination with goji berries and chrysanthemum to alleviate eye discomfort.
Eyes are among the body's most vital organs; once damaged or affected by disease, they are difficult to restore. Therefore, we can safeguard our pets' eye health through daily checks and care, while also nourishing their eyes by leveraging the gentle, restorative properties of traditional herbal ingredients.
Never be lulled into a false sense of security just because your pet is still young. All these proactive measures are taken with the hope that they can continue to look at us with bright, clear eyes and enjoy a better quality of life!
