What Are Carboxymethylcellulose Eye Drops?

Carboxymethylcellulose (CMC) is a type of artificial tear solution used to treat dry eyes. It belongs to a class of medications known as ocular lubricants. These drops help maintain moisture on the outer surface of the eyes and protect them from irritation.
Popular products include:
- Refresh Tears
- Celluvisc
- Refresh Liquigel
These formulations vary slightly in thickness and concentration but serve the same purpose: lubrication and hydration.
How Do Carboxymethylcellulose Eye Drops Work?
Carboxymethylcellulose acts as a viscosity enhancer. It forms a protective layer over the eye’s surface, reducing tear evaporation and improving moisture retention. This helps:
- Relieve dryness and irritation
- Improve tear film stability
- Protect against environmental damage (dust, smoke, wind)
The drops closely mimic the consistency of natural tears, making them comfortable for regular use.
