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.
