From the exterior visual angle, the cultivation of visual literacy depends on social education and the public self-education, but from the interior visual angle, the visual literacy deals with the psychology of visual cognition, especially the Gestalt psychology.

从外部看，图像文本的识读、图像素养的培养，取决于社会教育和公众的自我教育；而从个体内部看，它与公众的图像认知心理密切相关。

Oculocutaneous albinism type 4 (OCA4) is characterized by hypopigmentation of the skin and hair plus the characteristic ocular changes found in all other types of albinism, including nystagmus; reduced iris pigment with iris translucency; reduced retinal pigment with visualization of the choroidal blood vessels on ophthalmoscopic examination; foveal hypoplasia associated with reduction in visual acuity; and misrouting of the optic nerves at the chiasm associated with alternating strabismus, reduced stereoscopic vision, and an altered visual evoked potential.

疾病特征： 4型眼皮肤白化病（OCA4）的特点是皮肤和头发的色素减退以及所有白化病类型都有的典型的眼部改变，包括眼球震颤、虹膜色素减少而使其呈半透明状、视网膜色素减少而使得脉络膜血管在眼底镜检时可见、与中央凹发育不全导致的视敏度降低以及视神经交叉处路径错误引起的交替性斜视、立体感降低和视觉诱发电位改变。

The usual test for visual acuity, the letter eye chart, may not, however, reflect the true nature of visual loss, says the American Academy of Ophthalmology. Other tests-which measure glare sensitivity, contrast sensitivity, night vision, color vision, and side or central vision-help nail down the diagnosis.

美国眼科学会表示，通常用于视力检查的字母检查表可能不能正确的反应视力的下降的原因，其他的检查，如检查眼镜的光敏感度，对比敏感度，夜视能力，侧视觉和中心视觉可以确诊是否患病。
