Product Overview
Preservative-free, long-lasting dry eye relief with trehalose and sodium hyaluronate to hydrate and protect the eye surface. Suitable for all dry eye sufferers including contact lens users.
Description
Thealoz Duo Eye Drops (10 ml) are preservative-free lubricating eye drops formulated to provide rapid, long-lasting relief from moderate to severe dry eye symptoms such as dryness, irritation, foreign-body sensation, redness, burning and tired eyes. The unique combination of trehalose and sodium hyaluronate (hyaluronic acid) helps to hydrate, protect and lubricate the ocular surface, stabilising the tear film and supporting natural eye comfort in challenging environments.
Trehalose is a natural sugar with protective and hydrating properties for surface cells, while sodium hyaluronate is a high-performance lubricant that holds water on the eye’s surface, offering lasting comfort. The solution is preservative- and phosphate-free, making it suitable for sensitive eyes and daily use.
These eye drops are suitable for adults and children (with guidance) experiencing dry eye due to screen use, air-conditioning, pollution, contact lens wear, ageing or environmental stress. They are compatible with all types of contact lenses.
How to Use
Adults and children aged 12 years and over (or as directed by a healthcare professional):
- Wash your hands thoroughly before use.
- Remove the bottle cap and avoid touching the tip of the dropper to keep the solution sterile.
- Tilt your head back slightly and gently pull down the lower eyelid.
- Apply one drop into the lower conjunctival sac of the affected eye(s).
- Close your eye gently after application to help distribute the drop.
- Replace the cap securely after use.

- For consistent symptom control, drops can be used throughout the day.
- Do not exceed the recommended frequency without consulting a pharmacist or doctor.
