Orta Avrupa\u2019da n\u00fcfusun yakla\u015f\u0131k y\u00fczde 15\u201320\u2019si miyop, yakla\u015f\u0131k y\u00fczde 5\u2019i ise hipermetroptur. <\/p>\n\n

Hipermetropide g\u00f6z genellikle normalden daha k\u0131sa yap\u0131da geli\u015fmi\u015ftir. Bu nedenle \u0131\u015f\u0131k \u0131\u015f\u0131nlar\u0131 ancak retinan\u0131n arkas\u0131nda odaklan\u0131r.<\/p>\n\n

Miyop g\u00f6zden farkl\u0131 olarak, hipermetropi belirli bir ya\u015fa kadar g\u00f6z merce\u011fi taraf\u0131ndan telafi edilebilir.

Bu nedenle hipermetrop ki\u015filer, ileri ya\u015flara kadar genellikle uza\u011f\u0131 iyi g\u00f6r\u00fcrler. Sadece \u00e7ok y\u00fcksek dereceli hipermetropide gen\u00e7 ya\u015flarda bile g\u00f6zl\u00fck kullanmak gerekebilir. Buna kar\u015f\u0131l\u0131k hipermetrop ki\u015filerde yak\u0131n okuma yetene\u011finin azalmas\u0131 daha erken ortaya \u00e7\u0131kar, yani ya\u015fa ba\u011fl\u0131 yak\u0131n\u0131 g\u00f6rememe sorunu daha erken hissedilir. <\/p>\n\n

Orta Avrupa\u2019da n\u00fcfusun yakla\u015f\u0131k y\u00fczde 15\u201320\u2019si miyop, yakla\u015f\u0131k y\u00fczde 5\u2019i ise hipermetroptur. Miyop g\u00f6z (k\u0131sa g\u00f6r\u00fc\u015fl\u00fcl\u00fck = miyopi)Yak\u0131n\u0131 net g\u00f6r\u00fcrs\u00fcn\u00fcz, ancak biraz daha uzaktaki nesneleri bulan\u0131k olarak alg\u0131lars\u0131n\u0131z.

Uza\u011f\u0131 g\u00f6rememe ne kadar \u015fiddetliyse, (negatif) de\u011fer o kadar y\u00fcksek ve lensler o kadar kal\u0131n olur. Daha iyi ve daha net g\u00f6rebilmeniz i\u00e7in odak noktas\u0131n\u0131n geriye, yani retina \u00fczerine kayd\u0131r\u0131lmas\u0131 gerekir.

Hipermetrop g\u00f6z (uzak g\u00f6r\u00fc\u015fl\u00fcl\u00fck = hipermetropi)Uzak nesneleri net g\u00f6rebilirsiniz, ancak yak\u0131ndaki nesneleri bulan\u0131k g\u00f6r\u00fcrs\u00fcn\u00fcz. Hipermetropide g\u00f6z genellikle normalden daha k\u0131sa yap\u0131da geli\u015fmi\u015ftir.

Miyop g\u00f6zden farkl\u0131 olarak, hipermetropi belirli bir ya\u015fa kadar g\u00f6z merce\u011fi taraf\u0131ndan telafi edilebilir.

Bu nedenle hipermetrop ki\u015filer, ileri ya\u015flara kadar genellikle uza\u011f\u0131 iyi g\u00f6r\u00fcrler. Sadece \u00e7ok y\u00fcksek dereceli hipermetropide gen\u00e7 ya\u015flarda bile g\u00f6zl\u00fck kullanmak gerekebilir. Buna kar\u015f\u0131l\u0131k hipermetrop ki\u015filerde yak\u0131n okuma yetene\u011finin azalmas\u0131 daha erken ortaya \u00e7\u0131kar, yani ya\u015fa ba\u011fl\u0131 yak\u0131n\u0131 g\u00f6rememe sorunu daha erken hissedilir.

Astigmatizma (kornea e\u011frili\u011fi = astigmatizma) Hem yak\u0131ndaki hem de uzaktaki nesneleri bozuk olarak g\u00f6r\u00fcrler.

Bu ba\u011flant\u0131lar \u00f6zellikle miyop ki\u015filer i\u00e7in \u00f6nemlidir. \u00d6rne\u011fin, hafif miyoplu\u011fu olan (yakla\u015f\u0131k -2 ila -3 diyoptri) bir ki\u015fi, uzaktaki nesneleri net g\u00f6rebilmek i\u00e7in her zaman g\u00f6zl\u00fc\u011fe ihtiya\u00e7 duyar.
