The fovea is the part of the retina responsible for sharp central vision.
焦点是视网膜的一部分，负责清晰的中心视力。
In order to see fine details, one must look directly at the target with the fovea.
为了看清细节，必须用黄斑直接注视目标。
The fovea contains a high density of cones, which are photoreceptor cells that provide color vision and function best in bright light.
黄斑含有大量锥形细胞，这些感光细胞提供色觉并在强光下工作最佳。
People with macular degeneration often have damage to the fovea, leading to a loss of central vision.
长有黄斑变性的人常常有黄斑损伤，导致中心视力丧失。
The fovea is about 5 mm in diameter and is located in the center of the retina.
黄斑直径约为5毫米，位于视网膜的中心。
To read small print, the eye must be focused so that the image falls on the fovea.
要阅读小字，眼睛必须聚焦，使图像落在黄斑上。
The fovea is the area of the eye with the highest visual acuity, or sharpness of vision.
黄斑是眼睛中视觉敏锐度最高的区域，或者说是视力最清晰的区域。
In some animals, such as birds of prey, the fovea is larger and more developed than in humans, allowing for even greater visual acuity.
在某些动物中，如猛禽类，黄斑比人类更大更发达，允许拥有更高的视觉敏锐度。
The fovea is also the region where the optic nerve exits the eye, creating a blind spot known as the foveal pit.
黄斑也是视神经离开眼睛的区域，在那里形成一个盲点，被称为黄斑凹。
As we age, the fovea can deteriorate, leading to age-related macular degeneration and other vision problems.
随着年龄的增长，黄斑会退化，导致与年龄相关的黄斑变性和其他视力问题。
