Decreased tear production can seriously impact your comfort and eye health. Understanding this condition is crucial for maintaining clear vision and preventing further irritation. Find a top optometrist near you to explore treatment options.
Decreased tear production occurs when your eyes are unable to produce enough liquid tears, known as aqueous fluid, to properly lubricate and protect the surface of your eyes. This condition, medically referred to as keratoconjunctivitis sicca, can lead to persistent dryness and discomfort, and if left unmanaged, may result in lasting damage to the corneal surface and declining vision. Understanding the causes and implications of reduced tear production is essential for preventing further irritation and maintaining clear, comfortable vision.
Our eyes rely on a complex, layered system to remain healthy. The tear film that covers your eyes is composed of three key layers: a thin fatty layer from the meibomian glands, an aqueous (water) layer produced by the lacrimal glands, and a mucus layer from conjunctival goblet cells. Together, these layers spread across the eye’s surface every time we blink to provide proper lubrication, wash away debris, and protect against environmental irritants. When the balance in these layers is disrupted, the tear film may fail to function as intended, leading to symptoms of dryness and discomfort.
When we talk about decreased tear production, we usually refer to a deficiency in the aqueous fluid portion of the tear film. Without an adequate aqueous component, your eyes cannot maintain the protective film necessary for optimal comfort and clear vision. Here’s the thing: even a slight drop in tear production can trigger a cycle of inflammation and irritation over time, underscoring the importance of early detection and corrective measures.
One of the most common drivers behind decreased tear production is the presence of autoimmune or inflammatory systemic conditions. Diseases such as Sjögren’s syndrome, sarcoidosis, lupus, and rheumatoid arthritis can harm the tear-producing glands. When these glands are compromised by inflammation or autoimmune attacks, they struggle to release sufficient aqueous fluid, leaving the eyes dry and irritated. Patients with such conditions need careful monitoring by their eye doctors to prevent further ocular surface damage.
Inflammatory processes not only reduce tear production but can also alter the overall balance of the tear film. The deficiency in tears might lead the eyes to feel gritty, burning, or even to experience a sandy sensation. By understanding the link between systemic inflammatory conditions and ocular dryness, patients and care providers can work together on strategies that include both managing the underlying condition and addressing the eye’s surface health.
Certain medications can inadvertently lead to decreased tear production. Drugs that are commonly prescribed for allergies, high blood pressure, depression, or even hormonal imbalances—like antihistamines, decongestants, hormone replacement therapy, and various antidepressants—may reduce the amount of liquid tears your eyes produce. It’s important for patients experiencing persistent dryness to review their medications with their health care providers, as adjustments or alternative treatments might help alleviate the symptoms.
Even treatments that are beneficial for other conditions can cause side effects on tear production. When medications reduce tear production, the eye’s ability to remain moistened continuously is compromised, potentially causing discomfort, streaky vision, and even long-lasting corneal damage.
Normal pain sensation in the eyes plays a crucial role in stimulating tear production. The corneal nerves, which help in sensing discomfort such as dryness or irritation, actually prompt the production of tears, acting as a built-in protective mechanism. When these nerves become desensitized—often due to viral infections like shingles, long-term contact lens use, or even certain types of laser eye surgery—the result can be a significant decrease in tear production. This further undermines the eye’s natural healing and regeneration processes.
Without the proper response from the corneal nerves, not only does tear production diminish, but the corneal surface may also suffer due to inadequate cell regeneration. This underscores the delicate interplay between sensory nerve function and tear production, and highlights why a comprehensive eye exam is essential in patients experiencing dry eye symptoms.
As we age, many physiological processes in our body begin to slow down, and tear production is no exception. Individuals older than 50 are more likely to experience a natural decline in tear production. In many cases, age-related hormonal changes, particularly in women undergoing menopause, further contribute to lowered tear secretion. This increase in dryness can lead to irritation, a gritty sensation, and may even impair everyday activities like reading or using a computer.
It’s common for older adults to notice that their eyes feel drier as they age. Recognizing this natural decline is important because it directs the need for more frequent eye exams and personalized care from our eye doctors to keep discomfort at bay.
While autoimmune conditions, medications, nerve desensitivity, and aging are the primary causes, several additional factors can also play a role in decreased tear production:
The combined effect of these factors may not only diminish the quantity of tears produced but also compromise the overall quality of the tear film. In patients facing multiple issues, it becomes even more critical to address each contributing factor through targeted eye care guidance.

When tear production drops, the symptoms are usually noticeable in both eyes. Here’s what many patients report experiencing when their eyes are not receiving enough lubrication:
These symptoms are not just minor inconveniences. They signal that the eyes are not receiving the proper moisture needed for cellular health and regeneration. Because the tear film acts as a protective barrier, any compromise in its production can set off a chain reaction, leading to further ocular surface damage over time.
Adequate tear production is essential not only for comfort but also for maintaining the overall health of the eye’s surface. Tears play a crucial role in flushing out debris, reducing the risk of infection, and facilitating the healing of small abrasions on the cornea. When tear production is insufficient, the eye becomes more susceptible to infections, chronic inflammation, and, in severe cases, permanent vision impairment.
The health of the corneal surface is particularly vulnerable. Without enough tears, the delicate corneal cells can become damaged over time, a process that may result in corneal scarring. This scarring can diminish the quality of vision and may even interfere with the eye’s ability to focus light correctly. Maintaining balanced tear production is therefore paramount for preserving clear vision and overall ocular comfort.
In essence, decreased tear production is not merely a cosmetic problem. It is linked to more serious underlying issues that can escalate if not addressed promptly and adequately. Regular check-ups with our eye doctors are advised for anyone experiencing these symptoms, ensuring that any emerging issues are caught early.
