Across
- 3. Characterized by the three separate attributes of hue, saturation, and luminous intensity, but in general usage the term refers to hue only
- 4. There is no L (long wavelength, or red) pigment. This makes it hard to distinguish between red and green, making reds look particularly dark
- 5. Our cones allow us to see details in normal light conditions, as well as color
- 6. Visual illusion causing retinal impressions to retain a phantom-like image of a previously present stimulus
- 8. These cues require integration of information from the two eyes and include signals about the convergence of the eyes and binocular disparity
- 10. The inability to discriminate between colors and to perceive color hues
- 11. Any chronic abnormal alignment of the eyes, making normal binocular fixation and binocular vision impossible
- 13. An eye with poor vision that is mainly caused by underuse, especially the unused eye in strabismus
- 16. Optical illusion where a pair of converging lines distorts the perception of two identically sized lines
- 17. There is no S (short wavelength) pigment. This makes it difficult to distinguish yellows, greens, and blues
- 18. Any of a variety of means used by the visual system to interpret the apparent size of a stimulus
Down
- 1. The most common form of the disorder involves the green or red receptors of the cone cells in the retina, causing a red-green confusion
- 2. One or both eyes turn inward toward the nose, also known as being cross-eyed
- 7. The faculty or state of being able to see
- 9. There is no M (medium wavelength, or green) pigment. This makes it hard to distinguish between red and green
- 12. Demonstrates how retinal size is determined by a combination of object size and viewing distance
- 14. Poor vision caused by abnormal visual experience in early life and not any physical defect of the eye
- 15. Any of a variety of means used to inform the visual system about the depth of a target or its distance from the observer
