What causes Blepharitis?
What causes Blepharitis?
Blepharitis is caused by an overgrowth of the bacteria that is normally found on the skin. It is usually due to seborrheic dermatitis or a bacterial infection. Both may occur at the same time.
The cause is overgrowth of the bacteria that is normally found on the skin.
Allergies and lice that affects the eyelashes may also cause blepharitis, although these causes are less common.
People who have blepharitis have too much oil being produced by the glands near the eyelid. This allows bacteria normally found on the skin to overgrow.
Who is at highest risk?
