Dry Eye Disease: Understanding, Relieving and Preventing with Thea Eye Care

Dry eye disease affects a growing number of people in Canada, largely due to increased screen time, indoor heating and air conditioning, contact lens wear and climate variations. Common symptoms include dry, irritated or red eyes, a gritty or sandy sensation, fluctuating vision and persistent eye fatigue.
Thea Laboratories, experts in eye health, offer preservative-free solutions designed to respect the eye’s natural ecosystem while providing long-lasting relief.

What Is Dry Eye Disease?

Dry eye disease occurs when the eyes do not produce enough tears or when tear quality is insufficient. As a result, the tear film can no longer effectively protect and lubricate the surface of the eye.
Common causes include:

• Prolonged screen use
• Air-conditioned or heated environments
• Natural aging of the eye
• Contact lens wear
• Certain medical conditions or medications

Without proper care, dry eye disease can become chronic and significantly affect daily visual comfort.

Thea: Recognized Expertise in Eye Care

For over 150 years, Thea has been developing innovative eye care solutions with a strong focus on tolerance and effectiveness. The brand is internationally recognized for its leadership in preservative-free ophthalmic products.
In Canada, Thea offers a comprehensive range of solutions for:

• Dry eye disease
• Eyelid and periocular hygiene
• Sensitive or irritated eyes

Thealoz Duo®: Comprehensive Care for Dry Eyes

Thealoz Duo® is a unique ophthalmic solution that targets the key mechanisms of dry eye disease. It stands out for being:

• Preservative-free, ensuring excellent tolerance
• Compatible with all types of contact lenses
• Formulated with an exclusive combination of trehalose (an invisible shield that protects eye surface cells) and hyaluronic acid (a high-performance hydrating agent that helps retain moisture longer)

This combination helps to:

• Protect ocular surface cells (bioprotection)
• Stabilize the tear film (the thin layer of tears that continuously coats the eye surface)
• Maintain long-lasting hydration
• Relieve symptoms of dry eye disease, from mild to severe

Thealoz Duo® easily fits into a daily eye care routine - at work, at home or on the go.
 

The Importance of Eyelid Care

Healthy eyelids play a key role in maintaining tear film balance. Poor eyelid hygiene can worsen dry eye symptoms and contribute to conditions such as blepharitis (inflammation of the eyelids, particularly along the lash line).

Thea Solutions for Eyelid Hygiene

• Blephaclean®: Sterile, preservative-free wipes, ideal for daily cleansing of the eyelids and eyelashes
• Blephagel® / Blephasol®: Gentle solutions designed to soothe and cleanse the sensitive skin around the eyes

These products are especially recommended alongside eye drops to support a comprehensive approach to eye health.
