Understanding Dry Eye Syndrome: A Holistic Guide from Management to Prevention

1. Causes of Dry Eye Syndrome: A Dual Perspective

Dry eye syndrome is an increasingly common ailment in modern society. Understanding it requires looking at both Western and Traditional Chinese Medicine (TCM) perspectives.

• Western Medicine Perspective: Western medicine attributes dry eye primarily to insufficient tear production or excessive tear evaporation. This is often linked to aging and hormonal fluctuations. Other common culprits include autoimmune diseases (such as rheumatoid arthritis, Sjögren’s syndrome, lupus, and thyroid disorders), medication side effects, blepharitis, meibomian gland dysfunction (MGD), and complications from ocular surgeries like LASIK or cataract surgery.
• TCM Perspective: In TCM, “the eyes are the window to the essence of all five organs and six viscera.” Dry eye is not just a localized eye issue but a reflection of systemic imbalance. The primary root causes include:
  • Liver and Kidney Yin Deficiency: TCM believes “the Liver opens into the eyes.” Only when Liver blood is abundant can the eyes be properly nourished. Meanwhile, “the Kidneys store essence, which generates Liver blood.” In our modern lifestyle, staying up late and excessive screen time drain Liver and Kidney Yin, leaving the eyes un-nourished and dry.
  • Qi, Blood, and Body Fluid Deficiency: Poor spleen and stomach function impairs the production and transport of Qi, blood, and body fluids. As a result, the eyes are deprived of vital nutrients. This is frequently seen in the elderly, weak individuals, or those recovering from severe illness.
  • Internal Dryness and Heat: Frequent consumption of spicy and fried foods damages the body’s fluids, preventing moisture from ascending to nourish the eyes.
  • Liver Qi Stagnation Transforming into Fire: High stress levels and suppressed emotions in modern life cause Liver Qi to stagnate, eventually turning into “fire.” This internal fire consumes the fluids around the eyes, leading to dryness.

TCM emphasizes syndrome differentiation and treatment (辨证论治), tailoring herbs to each individual’s unique constitution to improve eye health from the inside out.

2. Who is Most Vulnerable to Dry Eye Syndrome?

With shifts in modern lifestyles, the high-risk demographic has broadened significantly:

1. Improper Eye Habits: Students from primary schools to universities now heavily rely on computers for assignments, online classes, and video conferences. Working professionals spend hours staring at monitors and continue to look at their phones during commutes. Long hours spent in air-conditioned environments further accelerate tear evaporation.
2. Specific Professions and Environments: Long-term contact lens wearers, night-shift workers, shipyard workers who must wear safety goggles in dusty or polluted environments, and pilots or cabin crew who fly in extremely low-humidity cabins.
3. Age-Related Factors: Clinically, it is most prevalent among individuals aged 50 and above, particularly peri-menopausal and menopausal women. However, due to chronic sleep deprivation, heavy workloads, and frequent business travel, the onset age is dropping, with a noticeable surge in patients aged 30 to 40.

3. Symptoms: More Than Just “Dry” Eyes

Dry eye syndrome presents with a variety of localized and systemic symptoms:

• Ocular Symptoms: Dryness, burning sensations, and a gritty foreign body sensation (often described as feeling like sand in the eyes). Patients may experience itching, stinging, or a dull ache around the eye sockets. Eye fatigue, a strong urge to keep the eyes closed, frequent blinking, photophobia (light sensitivity), redness, and bloodshot eyes are also common. Clear or yellowish sticky discharge may increase. Ironically, some patients experience reflex tearing (a compensation effect) where the eyes water excessively due to severe underlying dryness. Lastly, patients suffer from blurred vision or an inability to sustain focus for long periods, which temporarily clears up after rubbing the eyes.
• Systemic Symptoms: Many dry eye sufferers concurrently experience dry mouth, a dry throat, sensitive skin, tinnitus, insomnia, and constipation.

4. Treatment Modalities

By blending the strengths of both medical worlds, we offer a more robust therapeutic approach:

• Western Treatments: Conventional care focuses on symptom relief, utilizing lubricating eyedrops or prescribing eye gels for more severe cases.
• TCM Management Approaches:
  • Herbal Medicine: Tailored to the patient’s specific pattern of imbalance. For instance, Yin-nourishing herbs are prescribed for Yin deficiency. Because the eyes are at the highest point of the body, TCM utilizes gentle, lightweight seed-based herbs in smaller dosages. These formulas have minimal side effects and are perfectly safe for long-term consumption.
  • Acupuncture: Fine needles are placed around the eye area—never into the eyeball itself. Some points directly correspond anatomically to the lacrimal glands and ducts, stimulating natural tear secretion. Our collaborative clinical research with the Singapore National Eye Centre (SNEC) and the Singapore Eye Research Institute (SERI) has demonstrated that combining herbal medicine with acupuncture yields significantly better results than using herbs or eyedrops alone. Thus, we highly advocate adding acupuncture for suitable candidates.
  • Herbal Eye Steaming: A soothing physical therapy using the warm steam of brewed Chinese herbs to hydrate the eye surface.

5. Can Dry Eye Syndrome Be Cured? (Management & Maintenance)

A frequent question we encounter is: “Will I need herbal medicine and acupuncture forever?” Our clinic adopts a data-driven approach. Before management approaches, we measure the patient’s Tear Breakup Time (TBUT) to classify the severity (mild, moderate, or severe). After 3 to 6 months of targeted management, we re-test the TBUT. This allows us to evaluate efficacy using both objective numerical data and the patient’s subjective feedback.

The ultimate goal of management is to alleviate active symptoms and smoothly transition into a maintenance phase. As your condition improves, herbal dosages and acupuncture frequency are gradually tapered. For example, your herbal intake may drop from two packets a day to one, then to every other day, and eventually to just 2–3 times a week. At this stage, the herbs act as a health supplement to support and strengthen your body’s natural functions. Similarly, acupuncture sessions can be scaled back from once a week, to once every two weeks, and finally to once a month. This systematic progression empowers patients to manage their eye health independently, returning for maintenance sessions only when necessary.

6. Prevention and Daily Eye Care

Proactive daily habits are your best defense against dry eyes:

• Healthy Eye Habits: Practice the 20-20-20 rule (every 20 minutes of close-up screen work, look at something 20 feet away for at least 20 seconds). Remind yourself to blink frequently, and spend more time outdoors or in open indoor spaces.
• Self-Care Exercises: When your eyes feel fatigued, close them to rest or gently massage the acupoints around the eye socket (such as Zanzhu and Taiyang points) in small circular motions. You can also tilt your head back and blink rapidly 10 times to naturally stimulate tear production.
• Lifestyle Adjustments:
  • Stay well-hydrated by drinking about 2 liters of water daily (the eyes receive roughly 10% of the body’s hydration).
  • Prioritize quality sleep and aim to be in bed before 11 PM to support the self-repair cycle of the Liver and Gallbladder meridians.
  • Maintain a light, nutritious diet and avoid drinking ice water.
  • Enjoy a cup of high-quality green tea around 10 AM and 4 PM to naturally refresh your body and soothe your eyes.
