Understanding Dry Eye Disease

Dry Eye Care

What Is Dry Eye Disease?

Dry eye disease (DED) is a common condition where the eyes do not produce enough tears, or the tears evaporate too quickly. Tears are essential for lubricating the eye surface, protecting against infection, and maintaining clear vision — so when tear quality or quantity declines, the eye surface becomes irritated and uncomfortable.

Common Symptoms

Symptoms often include a stinging or burning sensation, a gritty feeling as if something is in the eye, redness, blurred vision, and sensitivity to light. Paradoxically, some people experience watery eyes — the reflex overproduction of tears in response to irritation.

Main Causes

Age is a major risk factor, as tear production naturally decreases over time. Other common causes include prolonged screen use, dry or windy environments, air conditioning, certain medications, contact lens wear, and underlying conditions such as blepharitis or meibomian gland dysfunction.

Treatment & Relief

Lubricating eye drops (artificial tears) are the first-line treatment. Options such as Aquasight combine Sodium Carboxymethylcellulose and Glycerine for dual-action lubrication, while Hylusight uses Sodium Hyaluronate for superior moisture retention. For moderate cases, more advanced formulations like Aquasight Ultra provide enhanced tear film protection.

Lifestyle changes also help: follow the 20-20-20 rule during screen use, stay hydrated, and protect your eyes from dry or windy conditions.

When to See a Professional

If symptoms persist despite regular use of lubricating drops, or if you experience pain, vision changes, or discharge, consult an eye care professional for a complete assessment.
