* INCLUSION CRITERIA: In order to be eligible to participate in this study, an individual must meet all of the following criteria: * Stated willingness to comply with all study procedures and actively pay attention to visual stimuli and respond as appropriate. * Participant has visual acuity of 20/25 or better in both eyes. * Participant must be 18 years old or older. * Participant must understand and be willing to sign a written informed consent document. EXCLUSION CRITERIA: An individual who meets any of the following criteria will be excluded from participation in this study: * Participant has an ocular, visual, or oculomotor problem that in the opinion of the Principal Investigator (PI) and/or clinical associate investigator would interfere with the participant s normal eye movements, visual perception, or required tasks. * Participant has a history of eye patching (amblyopia or lazy eye). * Participant has a non-ocular condition (e.g., neuropsychological conditions) that in the opinion of the PI and/or clinical associate investigator would interfere with the participant s normal eye movements or visual perception.
What this study is about
In the sponsor’s own words, from the registry.
Background:
Vision is vital for many of our daily activities. Researchers want to learn more about how we aim our eyes (that is, what images, such as faces, immediately attract our attention) and how we direct our attention (that is, what we see and what we ignore).
Objective:
To study how healthy adults process and respond to visual images.
Eligibility:
Healthy people aged 18 years with no vision problems.
Design:
Participants will have 5 to 10 clinic visits over 2 to 4 months. Some participants may have up to 25 visits. Each visit lasts about 1 hour.
Participants will be screened. They will answer questions about their medical and eye history. They will have a standard eye exam; eye drops will be used to dilate the pupils. (They may skip this exam if they have had an eye exam at the NIH within the past year.)
Participants will perform eye movement tests. They will sit in front of a computer and view images that appear on the screen. They may be asked to respond to what they see by speaking, moving their hands, looking in a certain direction, or pushing a button. Their eye movements will be tracked.
For some tests, participants heads may be held steady using a chinrest and head strap. For some tests, they may wear a cap fitted with cameras that use invisible lights in front of their eyes.
