Although there are many different types of cells in the human eye, rods and cones are responsible for sensing light. Rods are more sensitive to light intensity than cones are to color. Rods have a considerably greater convergence and hence send more information per ganglion, making them more sensitive to light. This allows for crisper vision in low light conditions or the dark.

It is concentrated on areas of the retina that are predominately made up of rod photoreceptors when you are not looking directly at something. Compared to the cones, which are gathered in the area of the retina used for direct vision, they are more sensitive to low light.

  • More cones than rods are found in the fovea, the middle part of the eye that you perceive as the center of your field of vision.
  • Cones can only detect specific light frequencies, which are typically absent in dark spaces. The rods are more wavelength sensitive.
  • They are terrible at discriminating colors but excel at contrast. The fovea is surrounded by rods, so by avoiding direct eye contact with it, you can see more light coming from it.
