A yellowish tint of the sclera, or white of the eye, is a classic sign of jaundice and indicates problems with the liver. A blue or gray sclera is sometimes associated with osteogenesis imperfecta, a condition involving fragile bones. Excessive redness may be caused by a number of irritants, including bacteria, viruses, makeup, allergens, chlorine from swimming pools, etc.
