What is the most common cause of dry eyes?

dry eyes are usually caused by the problem of tearing production - the chemical balance of the tears is incorrect, or the eyes do not create enough tears. Any of these situations may be the cause of dry eyes. Dry eyes are sometimes also associated with other health conditions such as dehydration and sleep disorders. In addition, some types of drugs can cause eyes to feel dry and scratched. Mostly, the cause of dry eyes may not be a serious health, but sometimes other serious conditions can signal.

The healthy eye has a liquid film that covers the surface, referred to as a "tear film". This film consists of oil, water and mucus. These three elements should be chemically balanced, and if they are not, the eye can feel dry and unpleasant, even if it is often wet. Doctors usually treat this cause of dry eyes with drops designed to help balance elements in the eye film.

Another common cause of dry eyes is missing tears. This can be caused by a number of factors, but usually the result of stopped SLa well -known channel. Sometimes this condition can be perverted at home, without medical treatment. This home remedy includes massage of the skin just below the tear ducts for several minutes and repetition of the massage several times a day. Doctors usually give the same procedure, along with prescription eye drops.

Sometimes dry eyes can be caused by tear channels that flow too freely. In these cases, too much tears are created at once, causing the eye to distinguish them all. Sometimes, to repair this problem, tears can be partially closed. This is usually done using small plugs made of silicone to create a partial blockage of pipes. Another method is called thermal cauterization, which is performed by inserting a hot wire into the tear channel to reduce the tissue of the pipe. Thje usually a painful procedure that requires anesthesia.

for dry eyes that are the result of life -free problemsEdges, lack of sleep or dehydration, sometimes eye drops of over -the -counter eye conditions clarify the condition. Dry eyes caused by problems, such as these, are generally considered temporary and are unlikely to require a doctor. If the treatment does not help, it is probably good to see a doctor to see if there is a serious condition.
