Carboxymethylcellulose Eye Drops: Benefits, Uses, and Everything You Need to Know

What Are Carboxymethylcellulose Eye Drops?

Carboxymethylcellulose (CMC) eye drops are a type of artificial tears that are used to lubricate and moisturize the eyes. They are made from a cellulose-based polymer that is similar to the natural mucus that is produced by the eyes.

Uses of Carboxymethylcellulose Eye Drops

CMC eye drops are used to treat a variety of eye conditions, including:

• Dry eye syndrome: This is a condition in which the eyes do not produce enough tears to keep them moist.
• Irritation and inflammation: CMC eye drops can help to relieve irritation and inflammation of the eyes caused by allergies, contact lenses, or environmental factors.
• Corneal abrasions: CMC eye drops can help to protect the cornea, the clear outer layer of the eye, from scratches and other injuries.
• Post-operative care: CMC eye drops can be used after eye surgery to help the eyes heal and recover.

How Do Carboxymethylcellulose Eye Drops Work?

CMC eye drops work by creating a thin, protective film over the surface of the eye. This film helps to:

• Lubricate the eye and prevent dryness
• Protect the eye from irritants and other harmful substances
• Promote healing of the cornea
