Impaired depth perception is indeed a significant hazard during night jumps. In low-light conditions, the human eye struggles to gauge distances accurately, which can lead to difficulties in judging altitude, descent rate, and landing approach. This reduced ability to perceive depth can cause skydivers to misjudge their landing spot or the timing of their flaring maneuvers, potentially leading to hazardous situations upon landing.

While other options also pertain to challenges faced during night jumps, they do not specifically highlight the direct implications of a lack of light on perception. For example, increased speed of descent refers more to the physical dynamics of the jump rather than the sensory limitations experienced in low visibility. Decreased visibility from altitude is a related concern but is a broader topic that includes all visual factors, rather than focusing specifically on how it affects perception. Additionally, sunlight glare is not applicable to night jumps, as there is no sunlight present to cause glare. Thus, the unique challenge of impaired depth perception becomes the most critical hazard in these conditions.
