What are cones in the human visual system?
Understand the Problem
The question is asking about the function and characteristics of cones in the human visual system, which are photoreceptor cells in the retina responsible for color vision and visual acuity.
Answer
Cones are retinal cells enabling color vision by detecting light in different wavelengths.
Cones are photoreceptor cells in the retina that enable color vision by detecting light of different wavelengths: short, medium, and long (often associated with blue, green, and red). They function well in bright light conditions.
Answer for screen readers
Cones are photoreceptor cells in the retina that enable color vision by detecting light of different wavelengths: short, medium, and long (often associated with blue, green, and red). They function well in bright light conditions.
More Information
Cones are crucial for daylight vision and enable humans to perceive colors and fine details. There are three types of cones sensitive to different wavelengths, facilitating the perception of a full spectrum of colors.
Tips
A common mistake is confusing rods with cones; rods are responsible for low-light vision and do not assist in color detection.
