Carboxymethylcellulose (CMC) eye drops are a type of artificial tear solution used to relieve dryness and irritation in the eyes. Here’s some information about carboxymethylcellulose eye drops:

Composition: Carboxymethylcellulose eye drops contain carboxymethylcellulose sodium as the active ingredient. Carboxymethylcellulose is a viscous polymer that acts as a lubricant and moisturizer for the eyes. It helps to restore and maintain the natural moisture balance of the eyes, providing relief from dryness and discomfort.

Mechanism of Action: Carboxymethylcellulose eye drops work by forming a protective layer over the surface of the eye, which helps to retain moisture and prevent evaporation of tears. This helps to alleviate symptoms of dry eye syndrome, such as irritation, burning, itching, and foreign body sensation.
