Understanding Dry Eye Disease
Dry eye disease is a common but frequently underdiagnosed condition in which the tear film — the thin, protective layer covering the eye’s surface — is either insufficient in quantity or inadequate in quality. The result is a persistent range of uncomfortable symptoms that can significantly affect daily life: a burning or stinging sensation, gritty or sandy discomfort, redness, intermittent blurred vision, and, somewhat paradoxically, episodes of excessive watering. If left unmanaged, chronic dry eye can cause damage to the ocular surface and affect long-term visual quality.
Types of Dry Eye
Dry eye disease is not a single condition but a spectrum. The two main types are
Aqueous-deficient dry eye — where the lacrimal glands produce insufficient tear volume
Evaporative dry eye — where tears evaporate too quickly, most commonly due to Meibomian gland dysfunction (MGD), a condition affecting the oil-secreting glands along the eyelid margins
Identifying which type — or combination — is present is essential for selecting the most effective treatment. Dr. Gotecha evaluates each patient’s tear film and ocular surface comprehensively before recommending a management plan.
Causes and Risk Factors
Dry eye is increasingly prevalent in urban populations and is particularly common among:
- Professionals with prolonged daily screen exposure (reduced blink rate worsens tear evaporation)
- Post-menopausal women and older adults
- Contact lens wearers
- Patients on certain systemic medications including antihistamines, antidepressants, and diuretics
- People with autoimmune conditions such as Sjogren's syndrome or rheumatoid arthritis
- Those in air-conditioned environments — which is very common in Mumbai offices and homes
Preservative-free lubricating eye drops (artificial tears) — suitable for regular use
Warm compresses and lid hygiene for Meibomian gland dysfunction
Anti-inflammatory eye drops where ocular surface inflammation is present
Environmental modifications — humidifiers, reducing air-conditioning directly aimed at the face
Dietary guidance including omega-3 fatty acid supplementation
Dry Eye Treatment Options
Management is tailored to the cause, severity, and the patient’s lifestyle. Treatment options include:
Many professionals in Mumbai spend eight or more hours a day in front of screens, reducing their blink rate significantly and accelerating tear evaporation. Simple interventions — the 20-20-20 rule (every 20 minutes, look away for 20 seconds at something 20 feet away), conscious blinking, proper screen positioning, and humidity management — can make a meaningful clinical difference alongside prescribed treatment.

Frequently Asked Questions
A: Paradoxical tearing is a common and often confusing feature of dry eye. When the ocular surface becomes irritated due to poor tear quality, the eye triggers a reflex response causing the lacrimal glands to produce a sudden excessive flow of tears. However, these reflex tears lack the composition of normal tears and do not address the underlying dryness.
A: Preservative-free lubricating eye drops are generally safe for regular and long-term use. Drops containing preservatives may cause surface irritation with very frequent application. Dr. Gotecha advises patients on the most appropriate formulation based on their individual needs, frequency of use, and whether they also wear contact lenses.
