Dry Eye Disease: Causes, Symptoms, and Effective Remedies

Tear fluid is essential for keeping the eyes lubricated and shielded from infections. Comprising water, oils, mucus, and proteins, tears maintain eye comfort. Insufficient tear production leads to dryness, causing redness, irritation, and blurred vision. When the tear film breaks down, irritants can enter, and sometimes the eyes produce excess tears as a reflex. Environmental factors, medical conditions, medications, and lifestyle habits can all contribute to dry eye issues.

Dry eyes may also trigger an overproduction of tears in response to irritation. Tears serve to protect and cleanse the eyes from dust and debris.

Causes of Dry Eyes

Environmental elements like wind, dry air, heaters, and air conditioning can desiccate the eyes.

Medications such as antihistamines, hormonal contraceptives, and decongestants may decrease tear levels.

Advancing age, menopause, and certain illnesses like Sjögren’s syndrome and rheumatoid arthritis impair tear production.

Prolonged screen time and reading can intensify dryness.

Problems with eyelid glands that produce oils lead to faster tear evaporation.

Additional factors include LASIK procedures, allergies, hormone treatments, and extended contact lens use.

Other causes involve vitamin A deficiency, thyroid disorders, and sleeping with open eyes.

Signs and Symptoms

Itching, burning, redness, and light sensitivity.

Blurred vision and the feeling of grit or mucus inside the eyes.

Eyes tire quickly and may produce excess tears as a response to dryness.

If untreated, dry eye can lead to infections or corneal damage, risking vision loss.

Diagnostics

Consult an eye specialist if experiencing symptoms. Tests like slit lamp exams, fluorescein dye tests, and Schirmer’s test help evaluate tear production and quality, guiding appropriate treatment.

Treatment Strategies

Artificial tears: Eye drops that provide hydration.

Medications: Anti-inflammatory drugs such as cyclosporine or corticosteroids reduce inflammation and stabilize tears. Cholinergic medicines like pilocarpine can increase tear secretion.

Lacrimal plugs: Tiny devices inserted into tear ducts to decrease tear drainage and boost eye moisture.

Diet improvements: Consuming omega-3 fatty acids via diet or supplements supports oil production and reduces dryness.

Early identification of causes and proper treatment can effectively ease symptoms and prevent progression of dry eye disease.
