Questions and Answers
What is the definition of binocular depth cues?
What does convergence refer to?
The brain detecting depth from tension in eye muscles when focusing on close objects.
What is retinal disparity?
The slight difference in the location of visual images on the retinae, enabling depth perception.

Study Notes
Depth Cues Overview
- Depth cues are signals that help the brain determine distance and depth of objects.
- They can be classified into two main types: binocular and monocular depth cues.
Binocular Depth Cues
- Require both eyes to work together for effective depth perception.
- Critical for assessing the distance of nearby objects.
Convergence
- Refers to the inward turning of the eyes to focus on close objects.
- The brain detects depth through changes in tension of eye muscles; greater tension indicates closer objects.
Retinal Disparity
- Involves the slight difference in visual images on each retina due to different viewing angles.
- The brain fuses the images and compares disparities to judge depth and distance.
Monocular Depth Cues
- Only one eye is needed to gather depth information, though they are effective with both eyes.
- Utilize various visual signals to aid in depth perception.
Accommodation
- Refers to the lens's automatic shape adjustment to focus on objects at various distances.
- The ciliary muscles are monitored by the brain to maintain focus.
