Blepharitis is an inflammation along the edges of the eyelids. The eyelids can become irritated and itchy, and appear greasy and crusted with scales that cling to the lashes. People with blepharitis sometimes wake with their eyelids stuck together. Others may wake with dried tears around their eyes and a feeling of sand in their eyes. In this picture, the yellow around the eye is from a yellow dye sometimes used in diagnostic tests.
