The assessment of an individual’s ability to visually perceive the world in three dimensions, conducted via the internet, utilizes digital platforms to administer evaluations related to stereopsis, motion parallax, and other depth cues. These evaluations often involve identifying disparities in images presented to each eye or responding to stimuli that simulate movement in a virtual environment. As an example, a user might be asked to identify which of several objects appears closest or to align objects that seem displaced due to binocular rivalry.

The capacity to accurately judge distances is crucial for navigation, object manipulation, and various skilled activities. A diminished sense of this spatial awareness can impact everyday tasks, such as driving or sports, and may indicate underlying visual impairments or neurological conditions. Historically, clinical assessments were primarily conducted in person using specialized equipment. The advent of web-based methodologies offers increased accessibility, convenience, and the potential for widespread screening, though validation against traditional methods remains an important consideration.
