Supply High Quality Eye Drop Grade Hyaluronic Acid Powder For Eye Health

Eye drop grade hyaluronic acid refers to high-purity hyaluronic acid specifically used in eye drops, contact lens care solutions, and ophthalmic surgical auxiliary fluids. It usually exists in its sodium salt form, "sodium hyaluronate". This type of product has extremely high requirements for purity, biocompatibility, endotoxin content, etc., and must meet the quality standards of ophthalmic medicine or medical devices.

Characteristics:

Good biocompatibility: similar to tear composition, mild and non-irritating;
High moisturizing: locks moisture for a long time and relieves dry eyes;
Strong lubricity: forms a protective film, reduces friction and improves comfort.

Contact Lens Moisturizers:

1. Application Purpose:

Reduce friction and discomfort caused by wearing contact lenses;
Improve wearing comfort and tolerance time;
Keep lenses moist and prevent lenses from drying and deforming.

2. Application Advantages:

The molecular structure of eye drop-grade sodium hyaluronate can form a lubricating water film on the lens surface, significantly reducing the friction coefficient between the cornea and the lens.
Long-lasting moisturizing performance can last for several hours, providing a good experience for wearers of soft contact lenses and rigid gas permeable lenses (RGP).
It is often combined with other functional factors such as mannitol and borate buffer system with hyaluronic acid to improve the overall performance of lens care solution.
