\u00d6nceki tahminlerde 2015\u2019e kadar olan veriler kullan\u0131larak, d\u00fcnya n\u00fcfusunun yar\u0131s\u0131n\u0131n 2050\u2019ye kadar miyop olaca\u011f\u0131 \u00f6ng\u00f6r\u00fclm\u00fc\u015ft\u00fc.<\/p>\n

Asya\u2019da miyop oran\u0131 y\u00fczde 70\u2019e ula\u015fabilir<\/strong>
1990 ile 2023 y\u0131llar\u0131 aras\u0131nda, 5-19 ya\u015f grubundaki ki\u015filerin k\u00fcresel miyopluk oran\u0131 y\u00fczde 24\u2019ten y\u00fczde 36\u2019ya y\u00fckseldi.<\/p>\n

Miyoplu\u011fun en y\u00fcksek oldu\u011fu \u00fclke y\u00fczde 86 ile Japonya iken, en d\u00fc\u015f\u00fck oran y\u00fczde 0.84 ile Paraguay\u2019da g\u00f6zlemlendi.<\/p>\n

\u00c7ocuklar ve gen\u00e7ler aras\u0131ndaki miyop oran\u0131n\u0131n bu h\u0131zla artmaya devam etmesi halinde, 2050 y\u0131l\u0131na kadar d\u00fcnya genelindeki gen\u00e7 n\u00fcfusun yakla\u015f\u0131k y\u00fczde 40\u2019\u0131n\u0131n miyop olmas\u0131 bekleniyor.<\/p>\n
