Burning, itching, red eyes with sticky lids \u2013 the symptoms of blepharitis and dry eye are so similar that the two are often confused. In fact they frequently occur together, but they are not the same thing. In this article we explain the difference and why it matters for treatment.<\/p>\n

What blepharitis is<\/h2>\n

Blepharitis is inflammation of the eyelid margins – the narrow strip where your lashes grow. It’s common, often long-running, and tends to come and go rather than clear up for good. It’s also closely tied to dry eye; in fact, the two so often appear together that treating one usually means dealing with the other.<\/p>\n

The blepharitis–dry eye connection<\/h2>\n

The oil glands that keep your tears from evaporating open right onto that same eyelid margin. So when the margin is inflamed, those glands get caught in the crossfire – their oil thickens and struggles to flow, and the tear film loses its protective top layer. That’s why blepharitis so often drives evaporative dry eye, and why calming the lids and steadying the tears go hand in hand.<\/p>\n
