Thealoz is a prominent family of preservative-free ophthalmic products manufactured by Théa Pharmaceuticals, primarily engineered to manage and alleviate the symptoms of dry eye disease. The brand is highly regarded for its dual-action and triple-action formulations that focus not just on temporary lubrication, but on cellular protection and stabilizing the eye's natural ecosystem. 
 
 
Key Advantages
Preservative-Free System: Long-term use of eye drop preservatives can irritate the ocular surface. Thealoz avoids this by utilizing Théa's specialized ABAK multi-dose bottle, which features a 0.2 µm filter membrane to keep the solution sterile without harsh chemicals. 
Hypotonic Formulation: Chronic dry eye leads to hyperosmolarity (a high concentration of salts) in tears. Thealoz drops are hypotonic, meaning they dilute this excess salt build-up to immediately soothe stinging and burning. 
Dosage: The standard recommendation is to apply 1 drop per eye, 4 to 6 times daily, though you should follow the specific guidance of your optometrist or ophthalmologist.
