Did you know that there are three tear variants: basal tears, reflex tears and emotional tears? Basal tears are responsible for lubricating the eyes, whereas reflex tears are a response to foreign bodies, like dust, or irritants like chopping an onion. Emotional tears help the body purge stress-related chemicals like manganese and prolactin.
