Have you ever felt your eyes dry, itchy, or tired after a long day in front of a screen, in air-conditioning, or outdoors on a windy day? That uncomfortable feeling often means your eyes lack enough moisture. Eye drops can help—and one of the most effective ingredients in them is sodium hyaluronate. But why is it so suitable for eye care?

What is Sodium Hyaluronate?

Sodium hyaluronate is the salt form of hyaluronic acid, a natural substance found in skin, joints, and eyes. Its key ability is water retention—like a sponge, it holds many times its weight in water, keeping tissues hydrated.

Safe and Gentle for the Eyes

The eyes are very delicate, so eye drop ingredients must be mild. Sodium hyaluronate is biocompatible, meaning the body recognizes it as natural. It rarely causes irritation and is considered safe for daily use.

Long-Lasting Moisture

When used in eye drops, sodium hyaluronate forms a thin protective film on the eye surface. This helps prevent tears from evaporating too quickly and provides long-lasting relief from dry eye symptoms, compared to plain water-based drops.
 

Supporting Eye Health

By keeping the surface moist, sodium hyaluronate also supports the natural repair of eye cells. This is especially helpful for people with dry eye syndrome, contact lens users, or those recovering from certain eye treatments.

Widely Applied

Because it is safe, effective, and natural, sodium hyaluronate has become one of the most common ingredients in modern eye drops, offering both comfort and protection.

In Short

Sodium hyaluronate is used in eye drops because it hydrates, protects, and helps the eyes heal.
