Cone cells are specialized photoreceptor cells located in the retina of the eye. They are responsible for color vision and function best in bright light conditions. There are three types of cone cells, each sensitive to different wavelengths of light: short-wavelength (blue), medium-wavelength (green), and long-wavelength (red). This combination allows humans to perceive a wide range of colors.
Unlike rod cells, which are more sensitive to low light and help with night vision, cone cells enable us to see fine details and vibrant colors during the day. The brain processes signals from these cells to create the images we see, making them essential for visual clarity and color discrimination.
