The text states that 'Although light detection in the eye is the first stage in vision, remember that it is actually the brain that "sees." ' What does this statement primarily imply about the visual process?

  • A: The eye merely collects light, and the interpretation and perception of images occur in the brain.
  • B: The eye is capable of independent vision without any brain involvement.
  • C: Light detection is the only essential part of vision, and brain processing is secondary.
  • D: Vision is solely a mechanical process of light entering the eye and doesn't involve any neural interpretation.

Explanation

The text clearly states that 'Although light detection in the eye is the first stage in vision, remember that it is actually the brain that "sees."' and further explains that 'action potentials' are sent to 'visual centers of the brain, where images are perceived,' highlighting the brain's role in interpreting the signals into actual images.
