色盲測試

色盲测试：

四個組的測試：

“簡單數字組”，

“幾何圖形組”，

“動物圖形組”，

“複雜數字圖形組”

它適合徵召士兵先天性色覺缺陷檢測，承認大學的學生和中等專業學校和招聘工人。

色盲亦稱「色覺辨認障礙」，是指無法正確感知部分或全部顏色間區別的缺陷。通常色盲發生的原因與遺傳有關，但部分色盲則與眼，視神經或腦部損傷有關，也可由於接觸特定化學物質。英國化學家約翰·道爾頓在發現自己是色盲者後，於1798年出版了第一部論述此問題的科學專著《關於色彩視覺的離奇事實》。由於道爾頓的研究，該缺陷常被稱為道爾頓病，不過現時多用色盲中的一種——綠色盲以描述道爾頓的缺陷。

紅綠色盲人口佔全球男性人口約8%，女性人口約0.5%。其中約6%人口為三色視覺(色弱)，約2%人口為二色視覺(色盲)，極少數為單色視覺(全色盲)。

色盲通常被認為是一種缺陷，然而在特定情形下，色盲者相比於正常辨色力者更有優勢。不少研究指出，色盲者更擅長識別特定顏色的偽裝。這在進化論上可解釋先天性紅綠色盲在人群中驚人的高發率。

Color Blindness Test

Four group of testing:

"Simple Figures Of Digits Group",

"Geometry Group",

"Animal Graphics Group",

"Complex Figures Of Digits Group"

It suits the testing of the congenital color vision defects in conscripting soldiers, admitting students to the universities and the polytechnic schools and recruiting workers .

Color blindness or color vision deficiency is the decreased ability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of some eye, nerve, or brain damage, or exposure to certain chemicals.

Color blindness is usually classed as a mild disability, but in certain situations, color blind individuals have an advantage over those with normal color vision. There are some studies which conclude that color blind individuals are better at penetrating certain color camouflages .
