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