Many Possibilities: This is a broad question with many possible answers. Most commonly, chronic redness can come from inflammatory conditions including eye allergies, eye dryness, eye rubbing, episcleritis (a surface inflammation), and/or subconjunctival hemorrhages (small burst blood vessels on the whites of the eyes). Start with artificial tears for lubrication & make sure not to rub the eyes; see eye md if needed.

Red = Irritation: Redness is due to dilation of blood vessels and can occur with irritation. Irritation may stem from dryness, chemical exposure, allergy, autoimmune disorder, glaucoma, uveitis, viral conjunctivitis, bacterial conjunctivitis, surgery, trauma, uv exposure or burn, infection, and much much more. A good eye doc can help you narrow it down.
