"A study conducted by the University of Granada has scientifically proven that alcohol consumption markedly impairs night-vision because it increases the perception of halos\u2014luminous circles\u2014and other visual night-time disturbances. Moreover, this deterioration of vision is significantly greater in subjects with breath alcohol content in excess of 0.25mg/litre\u2014the legal limit for driving in Spain and other countries and, also, that recommended by the World Health Organization (WHO)."^^<http://www.w3.org/2001/XMLSchema#string>
