The intricate mechanisms of vision rely not only on the complexity of the eye but also on the nutrients that support its function and vitality. Among these vital nutrients, vitamins and hyaluronic acid stand out. They are essential elements in preserving and enhancing eye health. Their collective role extends beyond mere sustenance, delving into maintenance, protection, and the potential improvement of ocular well-being. Let’s have a detailed discussion about their features and uses.

Healthy Vision [1]

Vitamins: Nourishment for Optimal Eye Function

–Vitamin A: The Vision Vitamin

Vitamin A is renowned for its role in vision. It plays a crucial part in the structure of the eye. It contributes to the production of rhodopsin. That is a pigment found in the retina essential for low-light and color vision. Insufficient vitamin A intake may lead to night blindness and other vision impairments.

–Vitamin C: An Antioxidant Shield

As a potent antioxidant, Vitamin C safeguards the eyes from oxidative stress. In this way, it reduces the risk of age-related macular degeneration (AMD) and cataracts. Its presence in the eye’s tissues supports collagen synthesis and helps maintain the cornea and blood vessels.

–Vitamin E: Shielding Against Age-Related Issues

Vitamin E is another powerful antioxidant. It protects cells in the eyes from free radicals, so it potentially reduces the risk of cataracts and AMD. It collaborates with Vitamin C to fortify the eye’s defense against oxidative damage.

Hyaluronic Acid: Moisture and Support for Eye Health

–Hydration and Lubrication

Hyaluronic acid is noted for its moisture-retaining properties. These features contribute significantly to ocular hydration. It supports the maintenance of the eye’s moisture levels and ensures adequate lubrication for optimal comfort and clarity of vision.

–Eye Tissue Health

Beyond hydration, hyaluronic acid supports the health of eye tissues. Found in the vitreous humor and other ocular structures, it aids in maintaining the structural integrity of the eye and may potentially support healing after injuries.

Other Active Ingredients for Eye Health

Maintaining optimal eye health involves a combination of various nutrients and compounds. Here are some other key active ingredients known for their potential benefits in promoting eye health:

1. Lutein and Zeaxanthin:

• Benefits: These carotenoids are found in high concentrations in the retina and help protect the eyes from harmful high-energy light waves like ultraviolet rays. They may reduce the risk of age-related macular degeneration (AMD) and cataracts.
• Food Sources: Leafy green vegetables, eggs, and certain fruits.

2. Omega-3 Fatty Acids:

• Benefits: DHA (docosahexaenoic acid) is a type of omega-3 fatty acid. It is a major structural component of the retina. Omega-3s may help prevent dry eyes and support overall eye health.
• Food Sources: Fatty fish (salmon, trout, mackerel), chia seeds, flaxseeds, and walnuts.

3. Zinc:

• Benefits: Zinc is essential for the health of the retina and may help prevent AMD and night blindness. It plays a role in transporting Vitamin A from the liver to the retina.
• Food Sources: Meat, dairy products, nuts, and whole grains.

4. Zeaxanthin and Astaxanthin:

• Benefits: Similar to lutein, zeaxanthin, and astaxanthin are carotenoids with antioxidant properties. They may contribute to protecting the eyes from oxidative stress.
• Food Sources: Zeaxanthin can be found in kale, spinach, and collard greens, while astaxanthin is present in salmon, shrimp, and microalgae.

Dosage and Safety

Here are the recommended dosage and upper limits for some common vitamins for adults:

Take the case of Vitamin A (Retinol and Beta-Carotene). Its Recommended Dietary Allowance (RDA) or Daily Adequate Intake (AI) is 700 micrograms (2,333 IU) for women and 900 micrograms (3,000 IU) for men. And the Upper Limit is 3,000 micrograms (about 10,000 IU). [2]

Yet, before introducing new supplements or making significant dietary changes, it’s advisable to consult with an eye care professional or healthcare provider. They can provide personalized advice based on individual needs and any existing eye health conditions. In this way, you can achieve optimal eye health benefits without adverse effects.

Ultimately, a holistic approach that combines a nutritious diet, regular eye check-ups, and appropriate supplementation lays the foundation for clearer, healthier vision and sustained eye wellness throughout life’s journey.

Conclusion: A Visionary Approach to Eye Health

In the intricate symphony of vision, vitamins and hyaluronic acid emerge as key players. Each contributes unique elements crucial for maintaining eye health and function. While these nutrients cannot reverse severe eye conditions, their inclusion in a well-rounded diet or through supplements underscores their importance in supporting ocular vitality and potentially mitigating certain age-related issues.

Dry eyes can be a bothersome and uncomfortable condition that affects many people. Whether caused by environmental factors, aging, or underlying health conditions, finding relief for dry eyes is essential for maintaining eye health and comfort. While eye drops and other treatments are commonly used, there’s a powerful ingredient that has emerged as the ultimate moisturizer for dry eyes: hyaluronic acid (HA). Let’s explore how hyaluronic acid can provide much-needed hydration and relief for dry eyes.

Human Eyes

What Is Dry Eye Syndrome?

Dry eye syndrome occurs when there is insufficient moisture or lubrication on the surface of the eyes, which can lead to symptoms such as itching, burning, redness, and a gritty sensation. Dry eyes can be caused by various factors, including decreased tear production, excessive tear evaporation, or an imbalance in the composition of tears. It’s a condition that can significantly impact daily life and overall eye health.

Dry Eye Syndrome [1]

How Hyaluronic Acid Is Used to Relieve Dry Eyes?

Hyaluronic acid is a natural humectant that alleviates dry eye syndrome in the following ways.

–The Hydrating Power of Hyaluronic Acid

Hyaluronic acid is a natural substance in the body with a remarkable ability to retain moisture. It can hold up to 1,000 times its weight in water, making it an exceptional hydrating agent. When applied topically to the eyes, HA forms a protective barrier on the surface of the eyes, preventing moisture loss and promoting hydration. This helps to alleviate dryness and discomfort, providing relief to individuals suffering from dry eyes.

–Restoring Tear Film Balance

The tear film is a thin layer that covers the surface of the eyes, keeping them moisturized and protected. In individuals with dry eyes, there is often an imbalance in the tear film composition, resulting in inadequate lubrication. HA helps restore this balance by enhancing the quality and quantity of tears. It promotes the production of high-quality tears that effectively coat the eyes, reducing friction and soothing dryness.

–Soothing and Calming Irritation

Dry eyes often come with symptoms of irritation, such as redness, itching, and a burning sensation. Hyaluronic acid has soothing and anti-inflammatory properties that can help alleviate these discomforts. By moisturizing the eyes and reducing inflammation, HA provides relief and helps calm irritated eyes. Its gentle and non-irritating nature makes it suitable for those with sensitive eyes.

–Easy Application and Compatibility

Using hyaluronic acid for dry eyes is simple and convenient. It is available in various forms, including eye drops, gels, and ointments. Eye drops containing hyaluronic acid can be applied directly to the eyes for quick relief. These formulations are compatible with contact lenses, allowing individuals to experience the benefits of hyaluronic acid while wearing their lenses. Whether you’re at home, at work, or on the go, hyaluronic acid eye drops can be easily incorporated into your daily routine.

–Long-Lasting Hydration

One of the significant advantages of hyaluronic acid for dry eyes is its long-lasting hydration. Unlike traditional eye drops that provide temporary relief, hyaluronic acid creates a reservoir of moisture that gradually releases over time. This means that the eyes stay hydrated for longer periods, reducing the need for frequent reapplication and providing sustained comfort throughout the day.

Conclusion

In a word, hyaluronic acid is a game-changer when it comes to moisturizing dry eyes. Its hydrating properties, ability to restore tear film balance, and soothing effects make it the ultimate moisturizer for dry eyes. If you’re experiencing the discomfort of dry eyes, consult with an eye care professional to determine if hyaluronic acid eye drops or other formulations may be suitable for your needs. Embrace the power of hyaluronic acid and enjoy the relief and comfort of well-hydrated eyes.

Sodium hyaluronate, the salt form of hyaluronic acid, is a naturally occurring polysaccharide group of sugar in the human body. It is a popular ingredient in skincare and cosmetics due to its ability to hydrate and plump the skin. This sodium salt also has a wide range of applications in the medical field, particularly in anterior segment eye surgery. In this article, we will discuss the utilization and benefits of sodium hyaluronate in anterior segment surgery.

What Is Anterior Segment Surgery?

Anterior segment surgery involves operating on the structures in the front of the eye, such as the cornea, iris, and lens. These surgeries can range from cataract removal to corneal transplants. It is crucial to maintain the clarity of the cornea and the surrounding tissues to ensure a successful outcome. Sodium hyaluronate can play an essential role in achieving this.

Human Eyes

Benefits of Sodium Hyaluronate Employed in Anterior Segment Surgery

Sodium hyaluronate is a natural substance largely found in the extracellular matrix of connective tissues. It is in the aqueous humor and the vitreous, and it forms a protective coating on the corneal endothelium. Sodium hyaluronate and other viscoelastic substances, such as chondroitin sulfate and collagen, have been used for eye surgeries since the 1970s. These viscoelastic agents are used to protect and maintain the shape of the eye during surgery. They help create space for the surgeon to work and prevent damage to delicate structures as well.

Eye Anatomy

–Maintaining A Deep Anterior Chamber

The primary benefit of using this salt as a viscoelastic agent is its ability to maintain a stable anterior chamber during the operation. The anterior chamber is the fluid-filled space between the cornea and the iris, and maintaining its stability is essential for successful surgery. Sodium hyaluronate can help stabilize the anterior chamber by providing a cushioning effect and preventing the collapse of the chamber. Therefore, it is easier to separate and maneuver these tissues, and the damage to the cornea and other tissues can be minimized.

–Protecting the Corneal Endothelium

Besides, the excellent lubricating properties of sodium hyaluronate can help reduce the risk of damage to the corneal endothelium during surgery. The corneal endothelium is a layer of cells that lines the back of the cornea, which is crucial for maintaining corneal clarity. Damage to the corneal endothelium can result in complications such as corneal edema and decreased vision. If it got scratched, there would be serious vision problems because all light passes through it and any defect might lead to a “blind spot”.

–No Adverse Effect

Sodium hyaluronate is a substance widely present in the human body, and there is no report on its adverse effects. So, it is considered to have no adverse effects and is safe to take. It is also biocompatible, meaning it is well-tolerated by the body and does not cause adverse reactions. Moreover, sodium hyaluronate can be easily absorbed by the body and does not require removal after surgery.

Sodium hyaluronate is available in various forms, including gels, solutions, and ointments. The choice of form depends on the specific needs of the surgery and the surgeon’s preference. There is a variety of medical-grade sodium hyaluronates on our website. Send us an inquiry if you are interested.

Examples of Sodium Hyaluronate Used in Anterior Segment Surgery

You can find sodium hyaluronate as a surgical aid during ophthalmic surgeries including cataract extraction, corneal transplant, glaucoma infiltration, and intraocular lens implantation. With sodium hyaluronate products, the safety and reliability of anterior segment eye surgeries have been improved.

–Cataract Operations

Sodium hyaluronate was used as a surgical device for two cataract surgeries: intracapsular cataract extraction (ICCE) with corneoscleral incision and corneal incision. There were 80 patients divided in two groups. The first group used sodium hyaluronate products, while the control group employed a balanced salt solution (BSS) instead. It was proven that this sodium salt has a protective effect on the cornea and no side effects, such as intraocular pressure or inflammatory reaction, have been observed. [2]

–Intraocular Foreign Body (IOFB)

Diverse surgical instruments have been employed to remove intraocular foreign bodies (IOFBs). A 38-year-old healthy man suffered from a glass IOFB in the left eye after a glass exploration. Medical-grade sodium hyaluronate gel was used to remove the IOFB, which could avoid damage to the retina and make it easier to grasp the flat glass fragment. [3]

Conclusion

In a word, sodium hyaluronate is a useful tool in anterior segment surgery. Its viscoelastic properties can help maintain a stable anterior chamber and protect delicate structures during surgery. Its lubricating properties can reduce the risk of damage to the corneal endothelium, and its biocompatibility makes it a safe choice for use in surgery. If you are undergoing anterior segment eye surgery, be sure to discuss the use of sodium hyaluronate with your surgeon and learn about how it can benefit your surgery.

Sodium hyaluronate has been a buzzword for years because of its water retention effect in the cosmetic sector. However, this natural humectant also stands out for its protective functions in the medical field. Here, this article is going to discuss the medical uses of sodium hyaluronate. Hope that you can have a better understanding of how medical-grade sodium hyaluronate is employed in the treatment and pain relief of joints, eyes, etc.

Medical-grade Sodium Hyaluronate

What Is Medical-grade Sodium Hyaluronate?

–Basics

Sodium hyaluronate is a natural substance found in the human body. This sodium salt is a visco-elastic long-chain polymer of sugar units of Na-glucuronate-N-acetylglucosamine. It is widely present in the extracellular matrix of connective and neural tissues in our body. Sodium hyaluronate is also involved in cell differentiation, wound healing, and inflammation.

–Functions

Sodium hyaluronate plays an essential part in modulating the interactions inside our body. First, medical-grade sodium hyaluronate could form a viscoelastic solution, which serves as a protective barrier for our tissues and cells. The solution could also absorb mechanical stress. Last, this sodium salt is thought to provide nutrients to injured cells to promote tissue repair and cell growth. With these notable properties, medical-grade sodium hyaluronate is applied to treat arthritis, cataract, dry eye syndrome, and other diseases.

What Are the Medical Uses of Sodium Hyaluronate?

–Sodium Hyaluronate for Intra-articular Injection

Sodium hyaluronate is commonly employed to reduce the pain of osteoarthritis and other joint illnesses for its lubricating and protective functions.

Osteoarthritis

Sodium hyaluronate is a component of the joint fluid that lies between your bones and cartilage. The fluid acts as a lubricant and absorbs shock in the joint, so you can move smoothly. Nevertheless, people with osteoarthritis have less hyaluronic acid and less joint fluid, causing pain, swelling, stiffness, and other uncomfortable symptoms. If you have these symptoms, you just need an injection of sodium hyaluronate to recover the viscoelasticity of the articular fluid and stimulate new fluid production.

–Sodium Hyaluronate to Cure Eye Diseases

Sodium hyaluronate is also extensively used in ophthalmic surgeries.

You can use medical-grade sodium hyaluronate to make artificial tears to alleviate dry eye syndrome. These artificial tears can form stable water film on the ocular surface to moisturize your eyes for a long time. Therefore, you can be saved from redness, itchy eyes, and blurred vision.

Eye Drops

Sodium hyaluronate is one of the most popular ophthalmic viscoelastic devices (OVDs) used in cataract surgery. It generates a deep chamber and protects the corneal tissues. Sodium hyaluronate acts as an OVD in corneal transplant, intraocular lens implantation, and retina attachment surgery as well.

Sodium Hyaluronate for Skin

Sodium Hyaluronate can be found abundantly in the dermis, helping skin retain its moisture.

The skin remains hydrated and the surface is supple when the skin contains adequate concentrations of hyaluronic acid.

Sodium Hyaluronate for Joint

Joint fluid and articular cartilage contain hyaluronic acid at high concentrations. HA serves as a lubricant (preventing bone-to-bone friction) and as a cushion. This function allows our joints to move smoothly.
A joint function-improving agent with hyaluronic acid as its active pharmaceutical ingredient is a prescription drug.

Sodium Hyaluronate is injected into joints to treat patients suffering from knee osteoarthritis, periarthritis of the shoulder (also known as frozen shoulder syndrome), and knee pain from rheumatoid arthritis. Hyaluronic acid has been reported to have anti-inflammatory and pain-relieving effects in such uses.

Sodium Hyaluronate for Eyes

The vitreous body contains high concentrations of Sodium Hyaluronate, which provides cushioning and plays a role in maintaining the shape of the eyeball.

The skin around the eyes is found to be thinner than the skin on the rest of your face and shows age faster. Dermatologists recommend that you keep your skin around the eyes moisturized through the use of a suitable cream. Among the most powerful and effective ingredients are Retin A, a form of vitamin A, emollients and moisturizers, antioxidants, hyaluronic acid, and vitamin C. All these components boost the creation of collagen and elastin, tightening the skin and reducing the tiny lines around the eyes.

Hyaluronic acid is a very popular ingredient for topical applications in skincare. It is found in most body tissues, as a part of the extracellular matrix, or the fluid around the cells. It has been identified as an important component of the skin. Research has shown that HA is actively metabolized in the skin and is not simply a space filler but also participates actively in the circulation of food and waste products. It is widely used in lots of clinical and cosmetic applications as a vehicle to carry other ingredients deep into the dermis, the inner layer of the skin. Very popular as an ingredient of cosmetic fillers, some of which are injected into the skin for rejuvenation, it has been approved for topical treatment of actinic keratoses in the USA.

Medical-grade Hyaluronic acid content in the skin decreases with age. Although it is confirmed to be an effective scavenger of free radicals and effective in protecting from ultraviolet radiation, a part of the hyaluronic acid is destroyed as well by the free radicals in the process. That is why it is of crucial importance to supplement it with the use of various creams.

This extremely useful cream ingredient helps to keep your skin moist and agile, aiding in a healthy, youthful appearance. As a result, scientists are in the process of investigating anti-aging skincare formulations that can stimulate the skin’s own production of hyaluronic acid, resulting in improved skin moisture and less-prominent wrinkles. Additionally, you can find skincare products that are formulated with cosmetic-grade hyaluronic acid to help you maintain younger-looking skin. Hyaluronic acid is perfect for anti-aging skincare, deeply moisturizing the skin while fighting wrinkles and lines.

The first known cornea transplantation is claimed to be performed in 1905 by Eduard Zirm (at the Olomouc Eye Clinic, now the Czech Republic), making it one of the first types of transplant surgery successfully performed. There is information in the literature, however, that back in the 1970s, the implantation of the lens inside the eye was often followed by severe edema, due to cell damage during the surgery. The need for a viscous, clear, physiologic lubricant to prevent such cells from scraping was getting evident. The first HA products are reportedly developed in the 1970s and 1980s and later approved for use in eye surgery in a variety of ways.

Nowadays, special hyaluronan solutions, known as ophthalmic viscoelastic devices (OVDs), are widely used in surgery on the surface and inside the eye to prevent dryness and to stimulate faster-wound healing. Medical grade hyaluronic acid and a number of its derivatives facilitate procedures, including vitreoretinal surgery, cataract surgery, anterior segment surgery, glaucoma surgery, and corneal transplantation.

In some cases, these products could be directly injected into the eye during surgical procedures to maintain the shape of the eye.

Other hyaluronic acid-based biomedical products (various kinds of eye cells and tissue implants or substitutes) have also been showing excellent biocompatibility, and tolerance, and encouraging efficacy in ophthalmic surgery. Some of them have been extensively studied and approved others are still being investigated in the long process of official clinical confirmation and results in verification.

Apart from its surgical application, hyaluronic acid in an aqueous solution, under the form of artificial tears, has proved to be an effective means of reducing dry eye symptoms and improving the vitality of the eye cells.

How hyaluronic acid benefits our eyes?

Effective Hyaluronic Acid Rich Eye Cream

You cannot get the best results by just using face or skin moisturizers and creams. This makes it important to choose wisely between different brands and qualities of eye creams available in the market. Of course, this choice depends more on your skin type and the problem you are facing, but hyaluronic acid, being a natural ingredient, is useful in almost every case. So, whenever it comes to buying an eye cream, make sure you check HA is in the ingredient list.

Although eye cream is mostly used to remove wrinkles and dark spots moisturizing that area is important to maintain skin health. This hydration is due to water in the cream, but hyaluronic acid is more effective here. HA molecules can absorb up to 1000 times more mass of water than themselves helping to stretch the skin and make it more elastic. As a result, rigidness, and wrinkles under the eyes cure. Perhaps, the most important benefit you can get by using HA-rich eye cream is that you are least likely to suffer from any side effects. Hyaluronic acid, being a natural substance, prevents eye irritation. For treating the skin under the eyes, you need a gentle eye cream that may not harm you. For that, natural product is at the top of the preference list. In short, HA-rich eye creams are more gentle, hydrating, and safe.

Advancing Eye Surgery with Hyaluronic Acid

Hyaluronic acid is the main lubricant and a very important component of the jelly-like substance within the eye. Due to its natural uses in maintaining proper eye functionality, HA is being used to improve eye surgery outcomes.

The eyes contain even more hyaluronic acid than your joints, which signifies that the compound has a heavy role to play in their normal functioning. Experts have researched the effects of using a variety of chemicals during eye surgeries to prevent side effects or make the surgery go smoother. One of the many compounds used to achieve this is hyaluronic acid – although HA, in particular, is completely safe, non-toxic, and natural. Hyaluronic acid is used in many procedures including cataract surgery, vitreous detachment, and corneal transplantation.

The vitreous humor is a gel-like substance that fills our eyes acting as a very important structural component. Of this component, there are some major sub-components including water, hyaluronic acid, and collagen. The collagen and sodium hyaluronate for the eyes binds together to make an intricate structure that functions – under normal circumstances – to keep the eye stable. Since medical-grade hyaluronic acid is so substantial to the inside eye, it is commonly injected during surgeries which would cause internal fluid to leak. Hyaluronic acid can be used to replace the lost vitreous humor and eventually serve as a component of the new vitreous humor in the future.

Hyaluronic acid is being used in cataract surgery to cushion the negative impacts on what is known as corneal epithelial cells – a layer of cells lining the inner cornea. Before hyaluronic acid was administered during these surgeries, the cornea’s epithelial cell count would drop an astonishing 45% post-surgery. After a scientist found that HA worked wonders on rabbit test subjects, the chemical was put on trial in South Africa. The results were absolutely remarkable, with only a 9% cell loss compared to the prior 45% cell loss without HA. After these results were confirmed, cataract surgery techniques and devices were immensely improved. Radical surgeries were undertaken and completed without the destructive side effects which would occur without hyaluronic acid.

A Passive Component to Sustain Intra-ocular Conditions

Not only does HA do a lot to actively aid in the process of many eye surgeries, but it also serves as a passive component that merely sustains intra-ocular conditions. Either way, HA has allowed scientists to bring the field of eye surgery to the next level by offering safe, useful, and tested benefits. It has given professionals a lot of room to experiment due to its wide-ranging benefits with respect to the eyes.

The eye cream has a moisturizing effect. Besides reducing the problems of dark circles and bags, it also has the effect of improving wrinkles and fine lines. Eye cream is used to protect the thin layer of skin around the eyes. It has certain effects on bags, dark circles, crow’s feet, etc. But different eye creams have different main functions.

What are the types of eye creams?

There are many kinds of eye cream, which can be roughly divided into eye masks, eye gel, eye cream, etc. Functionally, they can be divided into moisturizing eye creams, compacting eye creams, anti-aging eye creams, anti-sensitive eye creams, and so on.

What are the main ingredients and effects of eye cream?

Peptides have many kinds, some of which focus on promoting the synthesis of collagen and hyaluronic acid in the dermis, and others on simulating the effect of botulinum toxin to deal with dynamic wrinkles.

Vitamin C can not only resist oxidation but also promote the synthesis of collagen in the dermis.

Vitamin E antioxidants can reduce light damage. Act on the deep layer of the skin, effectively moisturize and replenish water, so that the skin around the eyes is tender.

Vitamin B3 promotes the improvement of skin barrier function and alleviates photoaging.

Ginsenoside, the main component of Ginseng Extract, has good antioxidant and anti-aging effects.

Elderberry extract activates blood circulation and promotes microcirculation, mainly aiming at the black circle of the eye. Elderberry extract is generally low in content. If the content is too high, it will stimulate the skin.
