There are several causes of dry eye syndrome, including:
Decreased tear production: With age, the body's hormone levels decrease, and the secretory function of the lacrimal and meibomian glands decreases. In addition, people with rheumatoid arthritis, lupus erythematosus, diabetes, allergic diseases, thyroid diseases and vitamin A deficiency, long-term use of antihistamines, antidepressants, birth control drugs and drugs such as high blood pressure and Parkinson's disease, or the use of hormone substitution, laser eye surgery or damage to the lacrimal gland due to inflammation or radiation, etc., will reduce tear production and induce dry eye syndrome.
Environmental factors: Environmental factors such as dry climate, working in front of a computer for a long time, and smoking can all contribute to dry eye disease. These factors can make the eye environment too dry, causing tears to evaporate too quickly, which can cause symptoms such as dryness and pain in the eyes.
Age: As we age, the function of the body's endocrine system gradually declines, and the amount of tears secreted by the lacrimal glands also decreases, which increases the risk of dry eye disease.
Drug factors: Some drugs (such as antihistamines, monoamine oxidase inhibitors, etc.) have the effect of inhibiting tear secretion, and long-term use of these drugs may increase the risk of dry eye disease.
Diseases: Some systemic diseases (such as rheumatoid arthritis, diabetes, etc.) and eye diseases (such as conjunctivitis, keratine mucositis, etc.) can lead to insufficient tear secretion, resulting in dry eye disease.
Xi Lifestyle habits: Long-term wearing of glasses, lack of adequate sleep, poor diet and Xi habits may increase the risk of dry eye disease.
The above are common causes of dry eye disease, but please note that this is not the whole cause. If you have dry eye symptoms, it is advisable to consult a medical professional for diagnosis and**.
