Persistent dryness, scratching and burning in your eyes are signs of dry eye syndrome. Dry eye syndrome is a chronic lack of sufficient lubrication and moisture on the ocular surface of the eye. It's consequences range from subtle but constant irritation to ocular inflammation of the anterior (front) tissues of the eye.
As explained in the nutritional health section of our site, Omega-3 essential fatty acids are helpful in systemically reducing the inflammation of the accessory lacrimal glands of the eyes. In addition, it has been found that these same Omega-3 fatty acids are beneficial in allowing the oil glands in the eyelid to produce a healthy tear film, which helps control chronic lid disease.
