What is a visual impairment that makes it hard to perceive depth and distance?

The correct answer, depth perception, pertains to the ability to judge distances between objects and the spatial relationship between them. This skill is essential for activities such as driving, where understanding how far away other vehicles, pedestrians, and obstacles are can significantly affect safety and navigation. A visual impairment affecting depth perception can lead to difficulties in accurately assessing distances, which may result in misjudging how far to stop from a traffic signal or how to safely merge into traffic.

The other options, while related to vision, address different aspects. Color blindness refers to the inability to distinguish certain colors, which does not directly affect depth perception. Narrow vision describes a limited field of view, which can hinder awareness of the surroundings but does not specifically pertain to the ability to perceive depth or distance. Speed smear is related to the perception of motion and can occur when an object is moving quickly, leading to a blur effect, but it does not directly impact depth perception either. Understanding depth perception is vital for safe driving and navigation in various environments.
