※ 引述《sheshell (......)》之銘言:
: 在看PTT時黑底白字特別在畫面切換跳頁時
: 感覺字體會漂浮對不到焦點的感覺
: 眨眼時也會覺得特別不舒服
: 但流覽一般網頁就不會有這種不適感
: 兩眼都是高度散光並有視差約四百度
: 請教這是什麼原因造成 謝謝!!
其實所有人都有這問題..
這問題在國外許多討論版都有討論..
這現象說明 Webber Contrast 理論還有被修正的空間..
====================================================================
In general, the greater the contrast between the text and background,
the easier the information is to scan or read.
在一般的情況下..文字和背景的對比差異越大..資訊越容易被掃瞄及讀取..
When the background is darker than the symbols brightness contrast, acuity,
legibility, and other responses may not be as well predicted by the luminance
contrast statistics
當背景亮度低於符號亮度..準確度,辨識度,及其他反應可能無法被亮度對比數據所預測
Research studies consistently show that when compared to scanning or reading
light text on a dark background, people read black text on a white background
up to thirty-two percent faster.
許多研究一致顯示..比較掃視或閱讀速度..
暗字在白色環境下 速度會比 亮字在黑色環境下 高出 32% ..

黑底白字會降低閱讀速度..並比較容易產生眼睛疲勞..

Webber contrast
對於"相對較小,邊緣帶稜角的物體..如廣大單色背景下的符號或字母.."
"對比" 定義為 "(符號與背景亮度之差值/背景亮度)"
