What is one consequence of losing binocular vision?

Losing binocular vision can significantly impair depth perception, which is the ability to perceive the world in three dimensions and judge distances accurately. Binocular vision allows the brain to combine the slightly different images received from each eye to create a sense of depth. When an individual has binocular vision loss, the brain struggles to gauge spatial relationships between objects because it is relying on a single visual input instead of the two that provide a fuller context for depth. This can lead to difficulties with tasks that require accurate distance judgment, like driving or playing sports, where understanding how far away an object is critical to performance.

In terms of the other options, losing binocular vision does not lead to increased clarity or enhanced depth perception; in fact, it typically does the opposite. Additionally, binocular vision loss does not strengthen eye muscles—it can actually lead to issues such as eye strain or misalignment. The focus on how depth perception is affected highlights why impaired distance judgment is the direct consequence of losing binocular vision.
