Scotopic Vision

Scotopic vision refers to the ability of the human eye to perceive and interpret low levels of light, particularly under dim or dark conditions. This type of vision occurs primarily in the rod cells of the retina, which are highly sensitive to light and allow for the detection of movement and shapes, but not colors or fine details.

In a broader sense, scotopic vision can also describe the visual perception in animals that are adapted to a primarily nocturnal lifestyle.

Sample Sentences:

  • Even in near-total darkness, our scotopic vision enables us to navigate and distinguish basic forms.
  • Many nocturnal animals possess superior scotopic vision, granting them a clear advantage in hunting and survival at night.
  • In a psychological experiment, participants were shown images at varying light levels to assess their scotopic vision capabilities.
