10ml thealoz duo
Thea’s most advanced preservative-free combination of sodium hyaluronate and trehalose - for lubrication, hydration and protection against dry eye - in a hypotonic formulation that can be used with contact lenses.

THEALOZ® DUO works in two ways:
It’s key ingredient is trehalose, a natural substance present in many plants and animals that are able to survive in extremely dry conditions. Trehalose has properties which protect the eye’s surface and is particularly suitable for chronic dry eye symptoms and people exposed to dry environments.

Sodium hyaluronate adds moisture by holding water to hydrate and lubricate the surface of the eye.
This combination makes it the ideal choice for ALL dry eye sufferers, whatever the cause.

The drops can be applied as often as necessary throughout the day, and are also suitable for contact lens wearers to apply either before or during wear.

It is also available as a box of 30 single unit doses, which can be ideal for travelling.
