Summary
In this research study we want to test how people understand a visual scene when the same image is presented to both the eyes, but portions of these images are altered in terms of contrast, depth or in some cases motion.
Eligibility Criteria
Inclusion Criteria
- Better than 20/40 visual acuity in the worse eye
- No restrictions of the peripheral visual field: (at least 60 degrees vertically and 40 degrees horizontally)
- At least 14 years of age (no upper age limit)
- Able to give voluntary, informed consent
- Able to understand English
- Binocular vision parameters within normal limits (Stereopsis ≤ 100 arc sec on any stereo test)
Exclusion criteria
- Patients with any physical or mental disabilities, including cognitive dysfunction, balance problems, or other deficits that could impair their ability to respond to the stimuli presented in this study will be excluded
- Being unable to complete sessions lasting 2-3 hours
