Tearing may be a normal function of the attention . Excessive tearing, or teary eyes that aren't from normal crying, are often a symbol of an underlying health condition or disease. The tears of the attention come from the lacrimal gland , called the lachrymal gland , which is found above the outer eye. Tears are composed of water, oil, and antibodies. The moisture from tears on the front of the attention , the cornea, is important to stop damage to the cornea from drying and becoming inflamed (keratitis) resulting in corneal abrasion and corneal ulcer.
The tears drain from the attention through the tear ducts (lacrimal ducts) into the nose. If the tear ducts become blocked, tears can swell within the eye and fall excessively. This results in watery eye (epiphora), often mistaken for crying. Tear ducts can become blocked from infection and inflammation, both of which may also cause excessive tear production. Blockage of the tear ducts also can occur from diseases like sarcoidosis, lymphoma, IgG related disease, also as from trauma and radiation treatments.
The outer membrane of the attention is named the conjunctiva. Any irritation of the cornea or conjunctiva can cause watery eye. Inflammation of the conjunctiva from (conjunctivitis) infection, irritants (chemical splash, etc.), or allergy (hay fever) may be a common explanation for itchy, watery eyes, also as eye swelling. Infection of the attention can require antibiotics within the sort of prescription eyedrops. Regular use of over-the-counter eyedrops (artificial tears) are often very beneficial for treating chronic dry eyes, like from Sjögren's syndrome or with facial palsy (Bell's palsy) and inability to shut the eyelid.
