THEALOZ DUO eye drops

Thealoz Duo is a prominent preservative-free eye drop solution designed to treat moderate to severe dry eye syndrome. The product is a flagship brand of Laboratoires Théa, an independent pharmaceutical group that has specialized exclusively in ophthalmology for generations. The brand is known for its patented ABAK bottle technology, which allows the solution to remain sterile without the use of chemical preservatives.

Laboratoires Théa is a family-owned company headquartered in Clermont-Ferrand, France. While the company maintains a strong manufacturing presence in France, where approximately 60% of its products are made, its global scale involves production and distribution across multiple European locations to serve over 70 countries. The Chibret family, which founded the company, has been a leading name in French eye care since the 19th century, ensuring the brand remains under independent private ownership as it enters 2026 and beyond.
