Dry eyes – a common ailment with many influencing factors.

Dry, watery, red, burning, itchy, irritated eyes or a feeling of sand in the eyes – dry eye manifests in various ways, but it is always a burden for those affected. Many different causes can contribute to the development of dry eye: increased screen time or smartphone use, air pollution, UV radiation, dry heat, high ozone levels, hormonal changes, air conditioning or heating, general illnesses, contact lenses, eye surgeries and LASIK, as well as preservatives in eye drops, decreased tear production with age, or even eyelid malpositions are some examples of causes of dry eye.

What happens with dry eye? The tear fluid's task is to supply the cornea with oxygen and nutrients, to moisten it, and thus keep it transparent. Furthermore, it serves as a lubricant for the eyelids. Every few seconds, the tear film covering the eye breaks, one blinks, and a new tear film is distributed over the eye's surface. If one blinks too infrequently, the tear film breaks too quickly, or if something is wrong with its composition, the tear fluid can no longer properly fulfill its function. Symptoms of dry eye are the consequence. Behind the visible and palpable symptoms lie various mechanisms (damage to corneal and conjunctival cells, inflammation, tear film instability, hyperosmolarity), which set a veritable vicious circle in motion, so that the factors of dry eye constantly fuel themselves.

1. Once the vicious circle is activated, simply eliminating the original triggering factor is usually no longer sufficient – the use of supportive eye drops is recommended.

2. Eye drops for dry eye should be preservative-free, as preservatives (especially the most commonly used benzalkonium chloride) can additionally damage the eye.

3. Often, the focus of dry eye treatment is on moisturizing the eye surface, usually with hyaluronic acid. However, since dry eye can be based on a complex mechanism, pure moisturizing often falls short. Thealoz® Duo (naturally preservative-free) consists of two components: hyaluronic acid and trehalose. The combination of these two ingredients enables comprehensive intervention at various points in the aforementioned vicious circle. Thealoz® Duo – protects the eye thanks to trehalose.

Trehalose is a naturally occurring disaccharide that enables organisms to survive under extreme conditions. For example, it protects the desert plant "Rose of Jericho" from dehydration and allows this plant to bloom again even after years of drought: Thealoz® Duo also utilizes these protective properties of trehalose.

Through the combination of trehalose and hyaluronic acid, Thealoz® Duo counteracts the various aspects of dry eye.

Thealoz® Duo is free from preservatives and phosphates and is also suitable for contact lens wearers and children.
