What is the name of the light-sensitive cells in the retina that are responsible for color vision?
Answer
Cones
Cones are specialized photoreceptor cells in the retina responsible for color vision and detailed visual acuity in bright light conditions. The human eye contains three types of cone cells, each containing a different light-sensitive pigment (opsin) that responds maximally to different wavelengths: short (blue), medium (green), and long (red) wavelengths. Cones require higher light intensities than rods to function and provide excellent color discrimination. Humans have approximately 6-7 million cones concentrated in the fovea (central retina), explaining why central vision is clearest.
💡 Did you know?
Humans have three cone types sensitive to red, green, and blue; their combined signals create color vision across the entire visible spectrum.
