1. Rods:

* Function: Responsible for night vision and detecting low levels of light. They are highly sensitive to light and can distinguish between different shades of gray.

* Location: Found mostly in the peripheral retina, which is responsible for our side vision.

2. Cones:

* Function: Responsible for color vision and visual acuity (sharpness of vision). They require higher levels of light to function optimally.

* Location: Concentrated in the fovea, a small area in the center of the retina responsible for our central vision. There are three types of cones, each sensitive to different wavelengths of light, allowing us to perceive different colors:

* Red cones: Sensitive to long wavelengths

* Green cones: Sensitive to medium wavelengths

* Blue cones: Sensitive to short wavelengths

In summary:

* Rods: Night vision, low light sensitivity, peripheral vision

* Cones: Color vision, visual acuity, central vision

Both rods and cones work together to allow us to see the world around us.
