Advantages of Sodium Hyaluronate
Superior Biomimetic Moisturizing Properties: Sodium hyaluronate can lock in 1000 times its own weight in water, forming a uniform and long-lasting protective film of water molecules on the lens surface.
Intelligent Shear-Dilution Behavior: When blinking, viscosity decreases, making the eyes feel silky smooth; when not blinking, viscosity returns, locking in moisture and reducing tear evaporation.
Significant Relief of Dry Eye Symptoms: Sodium hyaluronate effectively prolongs tear film breakup time, relieving dryness, foreign body sensation, and fatigue caused by prolonged contact lens wear.
Promotes Corneal Repair: High-purity sodium hyaluronate has excellent biocompatibility, gently protecting corneal endothelial cells and promoting the self-healing of minor damage.
Applications
Contact Lens Re-wetting Drops: Apply directly to the eye during wear for instant relief of dryness.
Multi-Purpose Solutions: Used for cleaning, disinfecting, storing, and lubricating contact lenses.
Rigid Contact Lens Care Systems: Sodium hyaluronate provides long-lasting cushioning and protection for overnight orthokeratology lenses.
Customer Feedback
"Significantly improved initial lens wearing comfort"
-- R&D Director of an international contact lens solution company
"This high-purity sodium hyaluronate is used in our new generation of silicone hydrogel lubricant formulation. Testing shows that its extremely low endotoxin levels allowed the product to pass the most stringent eye irritation tests. Consumer feedback indicates that the lenses remain moisturized and comfortable even after 8 hours of wear."
"High batch stability gives us great peace of mind"
-- Purchasing Manager of an Asian ophthalmic pharmaceutical company
"As a long-term partner, the raw material has a very uniform molecular weight distribution and extremely high batch-to-batch consistency. This greatly simplifies our production process control and reduces the rejection rate."
"Excellent compliance support"
-- European Medical Device Compliance Expert
"During the EU MDR certification application process, the supplier provided extremely complete and standardized technical documentation and quality certificates, helping our contact lens lubricant to successfully launch in the European market."
