Causes of dry eyes
Dry and astringent eyes refer to a symptom that the tears on the surface of the eyeball are insufficient or of poor quality, leading to eye discomfort. It may cause eye pain, tingling, redness, blurred vision and other discomfort. So, what is the cause of dry eyes?
First of all, environmental factors are one of the main reasons for dry eyes. Air conditioned rooms, long-term use of computers, dry weather, etc. will lead to accelerated evaporation or excessive evaporation of tears, resulting in dry eyes.
Secondly, age is also a common reason for dry eyes. With age, the function of tear secretion gradually weakens, resulting in dry eyes. When women are in menopause, hormone changes will also aggravate the symptoms of dry eyes.
In addition, eye infection, eye surgery, keratitis and other conditions may also cause dry eyes. By understanding the causes of dry eyes, targeted measures can be taken to alleviate this problem.
How to deal with dry eyes
For the problem of dry eyes, we can deal with it from the following aspects:
First, keep a good indoor environment. In air-conditioned rooms, using a humidifier to increase air humidity, or placing a basin of water beside the computer, can effectively reduce the problem of dry eyes.
Secondly, appropriate eye exercises should be carried out. For people who use eyes for a long time, they can do eye relaxation exercises at regular intervals to relieve eye fatigue and improve tear secretion.
In addition, it is also very important to maintain good living habits. Adequate sleep, reasonable diet and regular eye care can improve the symptoms of dry eyes.
Finally, if the above methods can not alleviate the problem of dry eyes, it is recommended to seek medical help in a timely manner and seek professional doctors. The doctor will find out the cause of dry eyes through examination and give corresponding treatment plan.
The relationship between corneal refractive surgery and dry eyes
Corneal refractive surgery is a method to correct ametropia by changing the corneal curvature, which can effectively improve myopia, hyperopia and other refractive problems. However, some people worry that corneal refractive surgery will lead to dry eyes.
In fact, corneal refractive surgery may cause temporary dry eyes after surgery. This is because the corneal tissue is damaged during the operation, and the tear secretion function is temporarily weakened, resulting in dry eyes. Usually, this dryness will gradually ease after surgery.
However, the current corneal refractive surgery technology is very mature, and doctors will conduct a detailed eye examination before surgery to ensure that the patient is suitable for surgery. If the preoperative examination finds that the patient has dry eyes, the doctor may suggest that the operation be temporarily delayed or other treatment methods be used to solve the problem.
In general, corneal refractive surgery may cause temporary dryness of the eyes after surgery, but this symptom will generally relieve itself. If you are worried about the dryness after the operation, you can discuss it in detail with the doctor before the operation and make a decision according to the doctor's advice.
Summary
Dry eyes are a common eye problem, which may be caused by environment, age and other factors. In order to alleviate the dryness of eyes, we can adjust the indoor environment, maintain good living habits, and carry out eye exercises. Corneal refractive surgery may cause dry eyes after surgery, but generally it will relieve itself. If you are worried about dryness, it is recommended to communicate with the doctor to find a solution suitable for you.
