"cone cell" 的定义和意义

What is a "cone cell"?

A cone cell, located in the retina of the eye, is a specialized photoreceptor responsible for our color vision and visual acuity in brighter light conditions. Shaped like a cone, these cells contain light-sensitive pigments that respond to different wavelengths of light, enabling us to perceive a wide range of colors. Cone cells are concentrated in the central region of the retina called the fovea, which is responsible for our sharp and detailed vision. They are sensitive to red, green, and blue light, and their combined activity allows us to perceive a full spectrum of colors and distinguish fine details in our visual environment. Cone cells play a crucial role in our everyday visual experiences, such as appreciating vibrant colors, recognizing faces, and reading.
