In eye, Hyaluronic Acid acts as a shock absorber and lubricant and keeps the structures of the eye snug so that they work optimally. It only makes sense to have a shock absorber within the eyes to stabilize vision and protect delicate eye tissues.
Hyaluronic acid in the eye is found in a structure called the vitreous humor, which is a clear gel that fills the central part of the eye. It’s formed by a network of collagen and Hyaluronic Acid and occupies about 80 percent of the eyeball’s volume. The hyaluronic acid molecules are large coils that hold water; in the vitreous they are entrapped in a matrix of collagen fibers. Most of the collagen is at the surface region of the vitreous, where it comes in contact with the rest of the eye, giving it a somewhat more solid surface. There is less collagen in the central region, which is a more liquid portion, comprised of about 99 percent water. Collagen fibrils attach the
vitreous gel to points around its margin, particularly to the retinal and lens structures.
