What are the causes of dry, itchy, bloodshot eye?!

Usually dry eye syndrome. Try some over the counter eye drops for dry eyes. It could also be the beginning of an eye infection, like pink eye (conjunctivitis), a highly contagious eye infection. If you start to see a discharge from your eye, see an eye specialist for antibiotic drops. Yes, it can clear by itself, but it is safer to get your eyes checked by an eye specialist. In the meantime take precautions against spreading the disease to your healthy eye or those you live with, just in case you have contracted pink eye. Wash your hands frequently, try to avoid touching your itchy eye and keep your towels, washcloths and soap separate from others.
