Dry eye is a common phenomenon. Most people in life will use eye drops to relieve dry eyes, but some people will find that they are always dry, and the relief time after using eye drops is not long, which makes them particularly confused, but they don't know what to do. In fact, there is a reason for the frequent occurrence of dry eye, which are relatively common.
What is the reason why eyes are often dry?
First, use the computer for a long time
At present, many people need to sit in front of the computer for a long time to work, and their eyes need to stare at the electronic screen for a long time, which will reduce the number of blinks, and at the same time, they can't secrete enough tears to wet their eyes, and often feel dry eyes.
Second, wear contact lenses for a long time.
Some nearsighted people choose contact lenses, especially women, to avoid glasses affecting their appearance. Contact lenses float on the lacrimal gland. Long-term wear will make tears evaporate faster, which will easily lead to dry eye and make eyes often tired. Especially for some soft contact lenses, the time to evaporate tears will be shorter, and it is easy to feel uncomfortable in the eyes.
Third, the eyes are aging.
Some people may find that the elderly are more prone to dry and itchy eyes, which is mainly related to their age. With the increase of age, the secretion of tears in most elderly people will decrease, which will easily irritate the eyes and often cause symptoms such as dry and itchy eyes.
Fourth, the environment is too dry.
Too dry environment is also a cause of dry and itchy eyes. Due to the improvement of living standards, many people like to use air conditioners in summer and heaters in winter. These long-term use will make the indoor air dry, and staying indoors for a long time will also make the water in the eyes evaporate, causing dry eyes.
Five, caused by disease or trauma.
The reduction of normal lacrimal gland function in the eye can also lead to dry eye, such as congenital lacrimal gland loss and senile lacrimal gland function reduction, which will reduce the normal lacrimal gland function in the eye and induce dry eye. In addition, when the eyes are injured by the outside world, such as traumatic infection and inflammation, it will reduce the function of lacrimal gland and lead to dry eye.
Tips: When the symptoms of dry and itchy eyes frequently appear, you should first understand the reasons and then take measures according to the specific reasons. After all, there are many reasons for dry and itchy eyes. If you take measures blindly, it will sometimes hurt your eyes. In addition, we should also know that we should take good measures to protect our eyes in our daily life, keep our eyes clean and avoid trauma and eye diseases.
