正视

Emmetropia

正视表示视力状态,其中无限远的物体与眼睛透镜处于中立或松弛状态时处于锐焦状态。 当角膜的屈光力和眼睛的轴向长度平衡时,可以实现正常眼睛的这种状态,从而将光线精确地聚焦在视网膜上,从而获得完美的视力。 在正视状态下的眼睛不需要矫正。 正视眼是一种将眼睛放松和聚焦在超过6米或20英尺远的物体的状态。 来自该物体的光线基本上是平行的,并且射线不经力地聚焦在视网膜上。 如果目光转向更接近的地方,来自源的光线太分散,无法集中精力。 换句话说,眼睛会自动关注远处的东西,除非有意识地将焦点集中在其他地方。 对于野生动物或人类史前祖先,这种安排将是适应性的,因为它允许对远处的捕食者或猎物的警觉。 镜头的住宿在正常情况下不会发生。 在正视中,透镜在中心约为3.6毫米厚; 在住宿,它增加到约4。 Emmetropia describes the state of vision where an object at infinity is in sharp focus with the eye lens in a neutral or relaxed state. This condition of the normal eye is achieved when the refractive power of the cornea and the axial length of the eye balance out, which focuses rays exactly on the retina, resulting in perfect vision. An eye in a state of emmetropia requires no correction. Emmetropia is a state in which the eye is relaxed and focused on an object more than 6 meters or 20 feet away. The light rays coming from that object are essentially parallel, and the rays are focused on the retina without effort. If the gaze shifts to something closer, light rays from the source are too divergent to be focused without effort. In other words, the eye is automatically focused on things in the distance unless a conscious effort is made to focus elsewhere. For a wild animal or human prehistorical ancestors, this arrangement would be adaptive because it allows for alertness to predators or prey at a distance. Accommodation of the lens does not occur in emmetropia. In emmetropia, the lens is about 3.6 mm thick at the center; in accommodation, it thickens to about 4.

在英语 词典里emmetropia的定义

词典中的正视的定义是完美视觉的正常状态,其中平行光线聚焦在视网膜上而不需要调节。

The definition of emmetropia in the dictionary is the normal condition of perfect vision, in which parallel light rays are focused on the retina without the need for accommodation.
