Introduction
Watery eyes may be caused by bright light irritation, emotional factors, excessive fatigue, conjunctivitis, glaucoma, etc., and it is important to seek timely medical attention at a hospital. Follow the doctor's instructions for improvement through general treatments, medications, or other methods. In daily life, maintain good eye hygiene, keep the skin around the eyes clean and dry, and avoid rubbing the eyes with hands.
Excessive tearing may be caused by strong light stimulation, emotional factors, eye strain, conjunctivitis, glaucoma, etc. It is advisable to seek timely medical evaluation at a hospital and follow medical advice for improvement through general management, medication, or other treatments. Specific causes are analyzed as follows:
1. Strong light stimulation: When the eyes are exposed to intense light, the ocular muscles may automatically contract, leading to increased tear secretion and thus tearing. Prolonged exposure to bright light should be avoided to protect eye health.
2. Emotional factors: Tear secretion is regulated by the nervous system, and emotional changes can affect nervous system activity. Emotions such as excitement or sadness may trigger tearing. This is a normal physiological response and usually does not require specific treatment.
3. Eye strain: Prolonged use of the eyes can lead to excessive fatigue, which in turn increases tear secretion, resulting in the aforementioned symptoms. It is important to manage screen time appropriately and avoid prolonged use of electronic devices such as computers and smartphones.
4. Conjunctivitis: Conjunctivitis is typically associated with pathogen infection. Under inflammatory stimulation, symptoms such as tearing and redness of the conjunctiva may occur. It is recommended to follow a doctor's instructions to use medications such as chloramphenicol eye drops, ganciclovir eye drops, or ofloxacin eye drops to relieve symptoms.
5. Glaucoma: Glaucoma may be related to genetic factors. Increased intraocular pressure can easily cause symptoms such as eye discomfort, eye pain, photophobia, and tearing. It is recommended to use medications such as prednisolone acetate injection, mannitol injection, or betaxolol hydrochloride eye drops under a doctor’s guidance to alleviate symptoms.
In daily life, attention should be paid to eye hygiene. Keep the skin around the eyes clean and dry, and avoid rubbing the eyes with hands.
