Do you suffer from dry eyes?
Tears are produced by the lacrimal glands and spread over the surface of the eye by the movement of the palpebrae, forming a protective film for the cornea. Dry eye is characterised by a decrease in the quantity or quality of tears. The result is dry eyes. This usually causes visual discomfort. Other symptoms vary from one person to another: tingling, itching, the sensation of having something in the eye, eyelids sticking when you wake up, excessive tearing, hypersensitivity to light, etc. Do you have one or more of these symptoms? Dry eyes are waiting for you... Consult an ophthalmologist!
