Dry Eye - Uncovering the causes and recognising the symptoms
🔍 More than just gritty eyes — Dry eye syndrome (DES) affects millions worldwide, but it’s often misunderstood. It isn't merely a nuisance; for many, it can affect reading, driving, screen work, and quality of life. The good news? Understanding the root causes and early symptoms is the first step toward lasting relief.
Your tear film is a complex, three-layered structure (oil, water, and mucus) that keeps your eyes comfortable, nourished, and optically clear. When any part of this system breaks down, dry eye syndrome develops. Lets go through the most frequent causes and the hallmark symptoms — so you can recognise the condition and seek the right advice with us.
Dry eye is rarely caused by a single factor. Instead, it emerges from an imbalance in tear production, tear drainage, or tear composition. Experts commonly split causes into two main categories: aqueous deficient dry eye (too few tears) and evaporative dry eye (tears evaporate too fast) and have con Most patients have a mix of both.
Dry EYE TYPES
💧 Aqueous deficient
- Sjögren’s syndrome (autoimmune)
- Aging – tear glands shrink
- Medications (antihistamines, beta-blockers, antidepressants)
- LASIK / corneal surgeries
- Vitamin A deficiency (rare)
🌬️ Evaporative (most common)
- Meibomian gland dysfunction (MGD) – blocked oil glands along eyelids
- Blepharitis (eyelid inflammation)
- Low blink rate (screens, reading)
- Environmental: wind, dry AC, smoke
- Contact lens overwear
🎯 The most frequent underlying triggers
- Meibomian gland dysfunction (MGD) — the leading cause of dry eye. Your meibomian glands produce the oily outer layer of tears, which slows evaporation. When these glands become clogged or atrophy, tears evaporate instantly, leading to gritty, inflamed eyes.
- Digital device overuse — concentrating on screens reduces blink rate by 60–70%. Incomplete blinks fail to spread fresh tears, promoting evaporative loss and eye strain.
- Autoimmune & systemic diseases — Sjögren's syndrome, rheumatoid arthritis, lupus, and rosacea directly attack tear glands or alter tear chemistry. Diabetes also increases dry eye risk via nerve damage.
- Hormonal shifts — menopause, pregnancy, and oral contraceptive use affect tear production and gland function. Androgen deficiency is linked to MGD progression.
- Prescription & OTC medications — common culprits: antihistamines (allergy pills), decongestants, diuretics, certain antidepressants (SSRIs), acne medication (isotretinoin), and glaucoma drops containing preservatives.
- Eye surgery & contact lenses — LASIK, SMILE, and cataract surgery temporarily damage corneal nerves, reducing tear secretion. Long-term contact lens wear alters corneal sensitivity and can induce meibomian gland dropout.

📋 Recognising the symptoms: beyond 'dryness'
Surprisingly, many people with dry eye don’t initially complain of "dryness." The symptoms can be varied and sometimes counterintuitive — for instance, excess tearing in windy or cold weather is a classic sign of dry eye. Here’s what to look out for:
🔥Burning or stinging — like soap in the eyes
🏜️Grittiness or sandy sensation — a foreign body feeling
💧Excessive tearing (reflex tearing) — eyes flood because the cornea is irritated
🌫️Fluctuating or blurred vision — often clears with blinking or eye drops
😣Stringy mucus — thin filaments in or around the eyes
📖Difficulty reading / screen fatigue — discomfort worsens with sustained focus
👁️Heavy or tired eyelids — eye strain sensation
🌙Worse symptoms in the afternoon/evening — as tear film evaporates throughout the day🌬️Sensitivity to wind, dry air, or A/C — immediate discomfort in drafts
👓Contact lens intolerance — lenses become uncomfortable after a few hours
🧪 Why watery eyes happen in dry eye: When the ocular surface becomes dry and inflamed, it sends distress signals to the brain, which responds by releasing a flood of reflex tears from the lacrimal gland. However, these reflex tears are mostly water — they lack the oil and mucin layers that anchor tears to the eye, so they run off immediately, offering little lasting relief. This is why chronic tearing should be evaluated for underlying dry eye, not treated as "too much moisture".

🩺 When should you seek advice?
Mild, occasional dryness from staring at a screen or windy weather is common. But you should schedule a comprehensive dry eye exam if you experience:
- Daily or near-daily symptoms lasting more than 1–2 weeks
- Blurred vision that improves with blinking but keeps returning
- Redness, pain, or light sensitivity beyond simple irritation
- Difficulty wearing contact lenses that were previously comfortable
- Symptoms that interfere with driving at night, reading, or work productivity

🌿 Quick self-care & prevention
While medical therapy is often needed, these strategies can complement treatment and reduce flare-ups:
- Warm compresses & eyelid hygiene – 10 minutes of gentle heat, followed by lid massage, helps melt meibum blockages in MGD.
- Follow the 20-20-20 rule – every 20 minutes, look 20 feet away for 20 seconds, and blink fully.
- Use preservative-free artificial tears
- Increase omega-3 fatty acids (flaxseed/fish oil) – studies show improved meibomian gland function.
- Adjust your environment – use a humidifier, avoid direct air vents, wear wrap-around sunglasses outdoors.
🌟 Key takeaway
Dry eye is not trivial — it is a multifactorial inflammatory condition. Whether your main issue is evaporative loss from MGD, medication-induced tear deficiency, or autoimmune-driven inflammation, early diagnosis leads to better outcomes. Don’t just live with the irritation; modern treatments can restore comfort and clear vision.
