BLINDNESS, the condition of being blind (a common Teutonic word), i.e. devoid of sight (see also Vlsiou; and EYE: Diseases). The data furnished in various countries by the census of 1901 showed generally a decrease in blindness, due to the progress in medical science, use of antiseptics, better sanitation, control of infectious diseases, and better protection in shops and factories. Blindness is much more common in hot countries than in temperate and cold regions, but Finland and Iceland are exceptions to the general rule.' In hot countries the eyes are affected by the glaring sunlight, the dust and the dryness of the air, From statistics in Italy, France and Belgium, localities on the coast seem to have more blind persons than those at a distance from the sea. There are no late returns for Iceland, but the last available statistics gave 340o per million. A paper written in 1903 on blindness in Egypt stated that 1 in every 50 of the population was blind. The following table gives the number of blind persons as reported in the census of each country. Unless otherwise stated, it refers to the statistics of 1900. Country.
