Causes of dry eyes
When eyes are dry, the cornea and conjunctiva are not sufficiently moistened with tears. There are many different reasons for this, but they are usually due to external influences.
Dry and warm air in rooms, especially during the long heating period in winter, can cause the valuable tear film to evaporate more quickly. But drafts can also lead to a dry eye surface.
Reduced blinking when working for long periods at a computer screen, intensive use of smartphones or reading can reduce tear production. The surface of the eye is no longer sufficiently moistened with fluid and can dry out. Contact lens wearers also often suffer from dry eyes.
Of course, internal influences that are difficult to control can also lead to dry eyes. As we get older, tear production naturally decreases. Hormonal changes during menopause can also be responsible for a decrease in tear production. In fact, women are more often affected, as the decreasing concentration of the hormone estrogen has a major impact on tear production.
Certain diseases and medications can change the composition and amount of tear fluid to such an extent that continuous moistening of the eyes is no longer guaranteed.
