Eye Drop Grade Sodium Hyaluronate: Ideal For Eye Protection And Moisturizing
Eye drop grade sodium hyaluronate is a high-quality sodium hyaluronate specially developed for eye care products. Compared with medical grade sodium hyaluronate, it has higher purity, is gentler on the eyes, and is safer to use. Its molecular structure is extremely water-absorbent and can effectively capture and retain moisture, forming a moisturizing protective film on the eye surface to protect the eyes from external environmental stimulation.
Advantages
- Efficient moisturizing:Sodium hyaluronate molecules are highly absorbent and can quickly provide sufficient moisture to the surface of the eyes to maintain long-term moisture.
- Strong biocompatibility:Sodium hyaluronate is a natural biological macromolecule with good biocompatibility, will not cause allergies or irritation, and is suitable for long-term use.
- No preservatives, high safety:Sodium hyaluronate products in modern eye drops mostly adopt preservative-free formulas, which reduce potential irritation to the eyes and are especially suitable for long-term use and sensitive eyes.
- Quickly relieve discomfort:Sodium hyaluronate eye drops can quickly relieve eye dryness, burning and foreign body sensation caused by dry eye syndrome, giving immediate comfort.

Application
1. Relieve dry eye syndrome
Sodium hyaluronate is one of the core ingredients in the treatment of dry eye disease. By forming a moisturizing film on the ocular surface, reducing tear evaporation and stabilizing the tear film, it can significantly relieve dryness, burning sensation and foreign body sensation caused by dry eye disease.
2. Care for eye fatigue
Activities such as using electronic devices for long periods of time, reading, or driving can easily cause eye fatigue. Sodium hyaluronate eye drops can quickly lubricate the eye surface, reduce friction, and relieve the discomfort caused by eye fatigue.
3. Postoperative care support
After eye surgery (such as cataract surgery, laser vision correction, corneal surgery, etc.), sodium hyaluronate eye drops are used to keep the eyes moist, relieve postoperative dryness, and promote the healing of the cornea or other tissues.
4. Contact lens wearing assistance
Contact lens wearers often experience discomfort due to friction or dryness of the ocular surface. The high lubricity and moisturizing properties of sodium hyaluronate can effectively alleviate these problems and improve wearing comfort.
5. Protect the ocular surface from environmental stimulation
In dry air-conditioned environments, scenes with heavy sandstorms or heavy smoke, sodium hyaluronate eye drops can form a protective film to alleviate damage to the eyes from external stimuli and provide long-lasting moisture.
6. Assist in relieving allergic conjunctivitis
For eye itching, tearing and redness caused by allergies, sodium hyaluronate can reduce uncomfortable symptoms and improve eye health by lubricating and protecting the ocular surface.
7. Promote eye healing
Sodium hyaluronate promotes cell regeneration and tissue repair. Use after minor corneal injury or ocular surface irritation to help speed the healing process.
