They are more likely than visual discomfort (tingling, sensitivity to light or smoke, feeling of eyelids stuck, etc.), to be irritated to the cornea and even to eye infections .
The causes of dry eye are numerous. The first of these is aging , since 15% of people with this pathology are over 60 years old. Indeed, with age, the production of lacrimal glands decreases.

Please note: dry eyes are not always synonymous with dry eyes . It may be related, for example, to blue light screens or exposure of the eyes to irritating products. In this case, it is only temporary!
