Blepharitis, viral conjunctivitis, stye, hordeolum
and other eye conditions may have to be considered here. As for
rosacea, the presentation usually involves a rash which affects the cheeks. Severe forms usually affect the eyes and cause a sensation of eye dryness. It may also involve the nose. A complete ophthalmologic examination will help ascertain if eye involvement is present.
I understand the discomfort that this condition brings.
