3. Good Viscoelasticity
Sodium hyaluronate exhibits high viscosity under low shear conditions, helping to prolong the residence time of the solution on the ocular surface; it also maintains good fluidity during blinking, improving comfort.

4.Strong Biocompatibility
As a naturally occurring substance in the human body, hyaluronic acid is unlikely to cause irritation or immune reactions, making it suitable for long-term use.

Mechanism of Action
*Hydration and Moisture Retention: Sodium hyaluronate molecules have extremely strong hydrophilicity, allowing them to bind and lock in a large amount of water, forming a stable hydration protective layer on the corneal surface. This significantly improves ocular surface moisture, relieving dryness and irritation.
*Lubrication and Protection: Sodium hyaluronate's unique viscoelastic structure forms a uniform lubricating film on the ocular surface, effectively reducing friction between the eyelids and cornea, and minimizing discomfort and foreign body sensation during blinking.
*Tear Film Stabilization: Sodium hyaluronate works synergistically with tear fluid, enhancing tear film structural stability and delaying tear film breakup time, thereby reducing tear evaporation and improving dry eye symptoms.
*Promoting Repair: Sodium hyaluronate provides a favorable moist microenvironment for corneal epithelial cells, aiding cell migration and regeneration, accelerating the recovery process of damaged ocular surface tissues, and is suitable for postoperative and mild injury adjunctive care.
*Extended Residue Time: Due to its excellent adhesion and viscoelastic properties, sodium hyaluronate can prolong its residence time on the ocular surface, improving the efficacy of the active ingredients in the formula and enhancing the user experience.
