Dry eye syndrome sets in when the superficial tear film that protects, irrigates, and nourishes the outer layers of the eye, particularly the cornea and conjunctiva, is too poor or of poor quality and fails to adequately support tissue physiology.
Reduced eye blood supply makes the tissues “suffer,” which then become more prone to irritation and inflammation, leading to early eye discomfort and fatigue and other characteristic symptoms.
Suffering from dry eye syndrome are mostly women, who are affected by the disorder twice as often as men, mainly for hormonal reasons.
