Reflex tears are a type of tear produced by the body in response to irritants, such as smoke, onions, or strong winds. These tears help to wash away foreign particles and protect the surface of the eye. They are part of the body's natural defense mechanism to maintain eye health and comfort. Unlike emotional tears, reflex tears are primarily composed of water, electrolytes, and proteins. They are produced by the lacrimal glands and are released quickly to provide immediate relief from irritation. This process helps to keep the eyes moist and clear, ensuring proper vision and comfort.
