👉 Tears are a complex fluid produced by the lacrimal glands in the eyelids, playing a crucial role in maintaining eye health and comfort. They consist of water (about 99%), electrolytes, proteins, and various substances like lysozyme, which have antibacterial properties, and mucus, which helps tear film stability. Tears also contain enzymes that break down foreign particles and bacteria, protecting the eyes from infections. They are constantly produced and drained through the tear ducts, ensuring a balanced composition that lubricates, nourishes, and cleans the ocular surface. When tears are insufficient or improperly balanced, it can lead to dry eye syndrome, causing discomfort, irritation, and potential damage to the eye's surface.
