Hormonal changes significantly affect eye health, often leading to dry eye symptoms in women. Understanding the role of estrogen and other hormones is crucial for proper management and comfort.
Hormonal changes, particularly in women, can have a significant impact on eye health, contributing to changes in tear production and quality that may lead to dry eye. In this discussion, we explore the connection between hormonal fluctuations—from menopause to pregnancy and the use of oral contraceptives—and dry eye syndrome. Understanding this link is important for addressing the discomfort and vision issues that many patients experience.
Our eyes rely on a delicate balance of tear components to stay lubricated, nourished, and comfortable. Hormones such as estrogen, progesterone, and androgens play a pivotal role in managing this balance by influencing the production and stability of the tear film. When these hormones fluctuate or decrease, as they often do during different stages of a woman’s life, the quantity and quality of tears can be altered, leading to dry, irritated eyes.
For instance, estrogen helps regulate tear production and maintains the health of the ocular surface. When estrogen levels drop, as is commonly observed during menopause, the composition of tears changes, resulting in reduced lubrication. Along with estrogen, other hormones like progesterone and androgens also contribute to tear-film stability, making hormonal balance crucial for comfortable, healthy eyes.
Estrogen is a key hormone that influences various physiological systems, including the secretions that maintain a healthy eye surface. It plays a role in controlling the chemical composition of tears, which consists of water, mucous, and oil. A proper balance among these components is necessary for minimizing tear evaporation and reducing irritation.
During the natural aging process or as a result of events such as menopause, estrogen levels drop. This decrease can lead to subtle changes in the tear film, impairing its ability to effectively lubricate the eyes. In turn, this contributes to the development of dry eye symptoms such as grittiness, burning sensations, and blurred vision.
Interestingly, some studies suggest that in premenopausal women, periodic increases in estrogen during the menstrual cycle might contribute to temporary changes in tear stability, which can manifest as mild dry eye symptoms on certain days of the cycle. These fluctuations underscore the dynamic nature of tear production and the importance of hormonal balance in maintaining ocular comfort.

Progesterone, another important hormone, works in tandem with estrogen to modulate ocular surface health. It appears to have a protective role; however, its effects are closely linked to the levels of estrogen present. For example, in situations where progesterone levels are disproportionately high compared to estrogen, tear production may be altered, sometimes leading to symptoms of dry eye.
Women who experience significant shifts in these hormones—for instance, during pregnancy or while taking birth control pills—might notice that their eyes become more sensitive or uncomfortable. Although the impact of progesterone is often overshadowed by the more extensively studied role of estrogen, it remains an important piece of the puzzle in understanding dry eye syndrome.
Androgens, including testosterone, are present in both men and women. However, women typically have lower baseline levels of androgens, and further decreases in these hormones can push the balance toward conditions that foster dry eye. Androgens help regulate the functions of the lacrimal and meibomian glands—both of which are essential for proper tear production and stability.
A decline in androgen levels, which can occur naturally with aging or due to certain endocrine disorders, has been linked to meibomian gland dysfunction. This dysfunction is one of the leading causes of evaporative dry eye, where tears evaporate too quickly from the ocular surface.
Research indicates that even a subtle imbalance in androgen levels can lead to increased tear evaporation. Laboratory studies and clinical observations show that lower androgen levels correlate with reduced tear film stability and increased dry eye symptoms, especially in postmenopausal women.
Many life events are associated with significant hormonal changes, and each of these can influence eye health in distinct ways. Understanding these life stages can help clarify why some patients experience dry eye symptoms while others do not.
Menopause is one of the most well-recognized periods when women experience a dramatic shift in hormonal balance. The decline in estrogen levels during menopause is closely linked to a decrease in both the quantity and quality of tears. As estrogen helps to support the production and composition of the tear film, its reduction can lead to increased tear evaporation and ocular surface instability.
Moreover, studies have shown that women over the age of 50 are considerably more likely to report dry eye symptoms compared to their male counterparts. The replacement or supplementation of hormones through hormone replacement therapy (HRT) has had mixed results; while some forms of HRT may help improve tear film stability for certain women, estrogen-only therapies have been associated with an increased risk of dry eye by altering the natural balance of ocular surface lubricants.
Pregnancy introduces another set of hormonal dynamics that can affect eye comfort. The rapid hormonal changes during pregnancy can lead to increased ocular sensitivity, and some women may experience temporary episodes of dry eye. Factors such as the hormonal response to morning sickness—which can cause dehydration—and the natural fluctuations in estrogen and progesterone during this period can contribute to these symptoms.
For many women, these changes are temporary. After childbirth, hormone levels gradually realign, often leading to the resolution of dry eye symptoms. However, during pregnancy, the discomfort can be significant enough to require adjustments in eye care routines, such as using lubricating eye drops or revising contact lens wear schedules.
Oral contraceptives introduce another dimension to the hormonal influences on eye health. It has been observed that women who take oral contraceptives may experience changes in their tear production and overall ocular comfort. The hormonal formulation in birth control pills tends to alter the natural levels of estrogen and androgens, with some research suggesting that this suppression of androgen production contributes to reduced tear stability.
Studies have found that women on oral contraceptives may experience improvements in dry eye symptoms when treatments that enhance the quality of the tear film—like artificial tears containing components such as hyaluronic acid and galacto-xyloglucan—are used. These findings further support the idea that hormonal balance is closely tied to tear function and sensory comfort.
