Ak\u015fam saatlerinde ya\u015fanan g\u00f6z kurulu\u011fu, yanma ve batma hissinin uykuya ge\u00e7i\u015fteki konforu bozabilece\u011fini aktaran Tezcan, \u201cG\u00f6z kurulu\u011fu do\u011frudan uyku kalitesini bozmasa da rahats\u0131zl\u0131k hissi nedeniyle uykuya ge\u00e7i\u015fi zorla\u015ft\u0131rabilir. Bunun yan\u0131nda ekranlardan yay\u0131lan mavi \u0131\u015f\u0131k, biyolojik ritmi etkileyerek uykuya dalmay\u0131 geciktirebilir\u201d diye konu\u015ftu.

G\u00f6z sa\u011fl\u0131\u011f\u0131 i\u00e7in uykudan en az 2 saat \u00f6nce ekran maruziyetinin kesilmesi gerekti\u011fini aktaran Tezcan, \u201c1 saatlik s\u00fcre asgari bir s\u0131n\u0131rd\u0131r ve g\u00f6z yorgunlu\u011funu bir miktar azalt\u0131r. Ancak beynin melatonin salg\u0131lamaya ba\u015flamas\u0131 ve derin uyku faz\u0131na haz\u0131rlanmas\u0131 i\u00e7in 2-3 saatlik bir dijital karartma s\u00fcreci, uyku kalitesi a\u00e7\u0131s\u0131ndan \u00e7ok daha verimlidir\u201d dedi. Gece okuma \u0131\u015f\u0131\u011f\u0131nda amac\u0131n yeterli ayd\u0131nlatma sa\u011flarken g\u00f6z kama\u015fmas\u0131n\u0131 ve biyolojik ritim \u00fczerindeki olumsuz etkileri azaltmak oldu\u011funu s\u00f6yleyen Tezcan, \u201cMavi a\u011f\u0131rl\u0131kl\u0131 \u0131\u015f\u0131\u011f\u0131n azalt\u0131lmas\u0131 ve daha s\u0131cak spektrumlu ayd\u0131nlatman\u0131n tercih edilmesi \u00f6nerilmektedir. Bu nedenle gece okuma \u0131\u015f\u0131\u011f\u0131nda genellikle 2700\u20133000 Kelvin aral\u0131\u011f\u0131nda s\u0131cak\/g\u00fcn \u0131\u015f\u0131\u011f\u0131 tonlar\u0131 tercih edilmeli. Bu spektrumda mavi \u0131\u015f\u0131k i\u00e7eri\u011fi daha d\u00fc\u015f\u00fckt\u00fcr ve sirkadiyen sistem \u00fczerindeki uyar\u0131c\u0131 etkisi daha s\u0131n\u0131rl\u0131d\u0131r. Ayd\u0131nlatman\u0131n parlakl\u0131\u011f\u0131 da \u00f6nemlidir. \u00c7ok d\u00fc\u015f\u00fck ayd\u0131nlatma g\u00f6z\u00fcn s\u00fcrekli uyum yapmas\u0131na neden olabilirken, a\u015f\u0131r\u0131 parlak \u0131\u015f\u0131k ise kama\u015fma ve kontrast kayb\u0131na yol a\u00e7abilir. Okuma i\u00e7in genellikle 450\u2013500 l\u00fcmen civar\u0131nda lokal ayd\u0131nlatma yeterli kabul edilir. Bunun yan\u0131nda \u0131\u015f\u0131\u011f\u0131n do\u011frudan g\u00f6ze de\u011fil, sayfaya y\u00f6nlendirilmesi ve dif\u00fcz bir \u0131\u015f\u0131k kayna\u011f\u0131 kullan\u0131lmas\u0131 g\u00f6rsel konforu art\u0131r\u0131r\u201d diye ekledi.<\/p>\n\n\n\n
