Eyes - this is the most sensitive human organ, which is easily affected by external factors, it responds to stimuli and to the general well-being of a person. Protecting himself from irritation, he weeps; every person has encountered such a feature. But there are several reasons why the eyes watery.
Tearing of the eyes is a common physiological process. They tear most often on the street. Wind, frost, heat, sun rays - all these are natural irritants for our organs of vision. The fact that the eyes are watery even when entering the room causes discomfort to people, especially women who use cosmetics. Eyes are still sore and swollen.
You can protect yourself from the bright sun and wind with the help of sunglasses, but you can’t hide from the frost in any way.
From the frost and wind, the lacrimal canal narrows, because of this the flow through this canal decreases and, not having time to get into the nasopharynx, the tears come to the surface. In the wind, our organs of vision are protected, enhancing the release of fluid, which helps to protect against dust and dirt.
When is the reason why the eyes watery, is a normal physiological process?
The above reason - this is a reaction to weather conditions, is a completely natural process, but there are other reasons for this phenomenon. Tears come when we cry, yawn, after sleep. These are manifestations of normal human physiology. Why are my eyes watering in the morning? Thus, the body moisturizes the eyeball, which has dried up during sleep.
Why are watery eyes, if it is not about physiology? There are some diseases, one of the symptoms of which is tearing. This happens regardless of weather conditions and physiological factors. Such pathologies include:
- Conjunctivitis and other pathologies characteristic of a change of seasons. The cause of such diseases is an infection that provokes inflammation of the eyeball.
- Allergy. Some types of allergies make your eyes swell, watery and inflamed. Thus, sensitivity to fluff, smells, dust, animal hair is manifested.
- Viral and infectious diseases. ARI, flu, tonsillitis are accompanied not only by cough, runny nose, but also by tearing.
- Foreign body. Cilia, hair, and grain of sand can get into the eye , which will cause such a reaction of the body. Remove the stimulus only with a clean handkerchief or napkin.
- When watching TV for a long time, hard work on the computer, reading books. Eyes are watery because blinking becomes rare during tension, during which hydration occurs. The eyeball dries up and the body reacts - tearing, the purpose of which is to moisturize the dried coat.
- Lack of vitamins in the body. A lack of potassium and vitamin B2 leads to fatigue, poor health, decreased immunity and a painful condition.
Ophthalmologists note that due to the tear film on the cornea, which is updated by the flow of fresh fluid from the lacrimal gland, the visual sharpness does not fall below 80%.
