  1. Light Sensitivity: Rod cells contain a pigment called rhodopsin, which is essential for their light-detecting capabilities. When exposed to light, rhodopsin undergoes a chemical reaction, initiating an electrical signal that is transmitted to the brain for interpretation.
  2. Peripheral Vision: Rod cells are densely packed in the outer regions of the retina, enabling us to have better peripheral vision. This is why we can often detect movement or objects in our peripheral vision, even in low light.

Cone cells function:

  1. Colour Perception: Cone cells contain different pigments that are sensitive to specific wavelengths of light, allowing us to perceive a wide spectrum of colours. There are three types of cone cells: red-sensitive, green-sensitive, and blue-sensitive, collectively enabling us to experience the vibrant world of colours.
  2. High Visual Acuity: Cone cells are densely packed in the fovea, the area responsible for our sharpest vision. This concentration of cone cells allows us to discern fine details and see objects with greater clarity.

FAQ’S:

What is the function of rod and cone cells?

Rod cells, the unsung heroes of our visual system, excel in low-light conditions. They provide peripheral vision, detect motion, and offer black-and-white or grayscale vision. On the other hand, cone cells, found in the central retina known as the fovea, are responsible for color vision and visual acuity.

What are rod and cone cells ?

Rod and cone cells are photoreceptor cells in the eye’s retina. Rod cells excel in low-light conditions, providing peripheral vision and detecting motion. They enable black-and-white or grayscale vision. Cone cells, concentrated in the fovea, are responsible for color vision and visual acuity.
