What causes dry eyes?

With the accelerated pace of modern social life and the popularity of electronic products, more and more people begin to feel the problem of dry eyes. So, what causes dry eyes? Let's discuss it in detail.

environmental factor

Environmental factors are an important reason for dry eyes. First of all, dry air will make the eyes lose water, and then cause dryness. In particular, the use of heating appliances in winter will increase the dryness of the air. In addition, exposure to the cold air after the air conditioner and long-term staring at the computer or mobile phone screen will lead to the evaporation of water in the eyes, causing dryness and discomfort.

In addition, the stimulation of dust, particles, harmful gases, etc. in the air to the eyes can also lead to dryness. In areas with serious industrial pollution, the incidence of dry eyes will be higher.

In addition, wearing contact lenses for a long time will also cause dry eyes. Contact lenses block the direct contact between the eyeball surface and the environment, reducing the wetness of the eyeball. Over wearing, incorrect cleaning and maintenance methods will further aggravate the dryness of eyes.

habits and customs

The occurrence of dry eyes is closely related to individual living habits. First of all, looking at close targets for a long time, such as computers, mobile phones, books, etc., will reduce the number of blinks, and the tears will volatilize too quickly, resulting in dry eyes. In addition, staying up late and poor eye posture will also aggravate the degree of dryness of eyes.

Incorrect eye posture is also a factor leading to dry eyes. If the eyes are excessively tired after being used for a long time, sitting still for a long time will make the eyes stay in the same position for a long time, which will easily cause eye fatigue and dryness.

Bad living habits also lead to dry eyes. For example, bad living habits such as smoking and drinking too much will cause damage to the epithelial cells on the surface of the eye, reduce the secretion of tears, and cause dry eyes.

Physical health

Some health problems can also cause dry eyes. For example, people's eyes are prone to dryness with age and deterioration of eye function. At the same time, some chronic diseases, such as diabetes, rheumatoid arthritis, will also affect the normal function of eye tissue, causing dry eyes.

Other factors

In addition, there are other factors that can also cause dry eyes. For example, the side effects of some drugs, such as antidepressants and antihistamines, can cause dry eyes. At the same time, eye fatigue, infection, eye surgery, etc. can also cause dryness.

To sum up, dry eyes are caused by many factors, including environmental factors, living habits, physical health and other factors. In case of dry eyes, seek medical advice and treatment from a professional ophthalmologist.
