    Application

    Artificial Tears
    Eye drop grade hyaluronic acid, due to its excellent moisturizing ability, forms a stable, hydrated protective film on the ocular surface. Used in artificial tears, it relieves dry eyes, stinging, and fatigue, improving eye comfort.
    Lubricating Eye Drops
    Its good viscoelasticity allows it to stay on the ocular surface longer, effectively reducing friction and improving dryness and foreign body sensation when viewing objects. Commonly used for daily care or by people who use their eyes for extended periods.
    Contact Lens Lubricating and Care Solutions
    Adding hyaluronic acid to contact lens care or lubricating solutions improves lens lubrication and wearing comfort, reducing dryness and discomfort.
    Viscoelastic Solutions for Ophthalmic Surgery
    High purity hyaluronic acid is used in certain ophthalmic surgical aids (such as cataract surgery) to help maintain intraocular space and protect corneal tissue.
    Post-operative Repair Eye Products
    Utilizing the gentle, moisturizing, and restorative properties of hyaluronic acid, these are eye drops used to aid in ocular surface repair after surgery or laser treatment.
