不同颜色视野范围比较初探

视野是单眼固定注视正前方所能看到的空间范围,此范围又称为周边视力。不同颜色视野的大小,不仅与面部结构有关,更主要的是取决于不同感光细胞在视网膜上的分布。利用视野计对眼的白色、红色、蓝色、绿色视野进行测定比较,结果表明:白色视野最大,其次为蓝色视野和红色视野,绿色视野最小;在相同条件下,不同视力眼能看到的视野范围是不同的,视力越好,视野范围越大。

The different color field of vision scope at the beginning ofcomparison searches

The field of vision is the simple eye fixed gaze deadahead can see the spatial scope,this scope is called the peripheral vision.Different color field of vision size,not only with facestructure related,what is main is decided by the differentphotosensitivity cell on retina distribution.Using theperimetercross-eye white,is red,the blue color,the green field of visioncarries on the determination,indicated compared with the result:White field of vision biggest,next is the blue color field of visionand the red field of vision,the green field of vision is smallest;Under the same condition,the different vision eye can see the field of vision scope is different,vision better,the field of vision scopeis bigger.
