"fovea" 的定义和意义

What is "fovea"?

The fovea is a small, central pit located in the retina of the eye. It is responsible for sharp central vision and the perception of fine details. The fovea contains a high concentration of cone cells, which are specialized photoreceptor cells that are sensitive to light and responsible for color vision and visual acuity. Its location in the center of the retina allows for precise and detailed vision when looking directly at an object. The fovea plays a crucial role in activities that require precise vision, such as reading, driving, and recognizing faces.
