The full form of HMC eye, when referring to eye drops or solutions, is Hydroxypropyl Methylcellulose.
Hydroxypropyl Methylcellulose (HPMC) is a non-ionic, water-soluble polymer used as a lubricant in eye drops to treat dry eye conditions. It acts similarly to natural tears, providing temporary relief from burning, irritation, and discomfort caused by eye dryness.
Here's a breakdown:
- Hydroxypropyl: A chemical group attached to the cellulose molecule.
- Methylcellulose: A cellulose derivative that is water-soluble.
- HPMC: The combination of these modifications gives the polymer its lubricating and film-forming properties beneficial for dry eyes.
Therefore, when you see "HMC eye" on an eye drop product, it's referring to the active ingredient Hydroxypropyl Methylcellulose.
