The tear film produced by the tear glands and ducts has three important layers: mucous, aqueous fluid, and fatty oils. Normally, this combination of agents ensures the eye's surface remains well lubricated, smooth, and protected from foreign debris. However, people with dry eyes have some kind of disruption or dysfunction in their tear production. The two primary things that can go wrong include a decrease in tear production and an increase in tear evaporation, and, sometimes, people can have problems with both.
Aging, certain medical conditions, and even insensitivity of the corneal nerve can lead to lacking tear production. Eyelid issues, eye allergies, exposure to dry air, and even less frequent blinking can cause problems with heightened tear evaporation. Some of the things that can contribute to dry eyes for either lacking tear production or heightened tear evaporation include.
Dry Eyes During and After Menopause
Regardless of whether you are male or female, your risk of developing dry eye as you get older grows. This is because tear production naturally wanes with age. However, postmenopausal women can be more at risk.
Large-scale studies have shown that almost double the number of women who are over 50 years of age have problems with dry eyes compared to men in the same age group. This, along with several studies, points to the fact that there is a hormonal factor behind women being more susceptible to dry eye syndrome.
