What primarily limits vision during a night dive?

Vision during a night dive is primarily limited by the illumination capabilities of your lights. At night, natural light is significantly reduced, making it essential for divers to rely on artificial lighting for visibility. The quality, intensity, and range of the lights used will determine how much of the underwater environment can be illuminated and seen clearly. Insufficient or inadequate lighting can lead to a limited field of view, causing difficulties in navigating, identifying marine life, and overall situational awareness.

In this context, while water temperature, diving experience, and depth can certainly influence aspects of the dive experience, they are not the primary factors that affect visibility. Water temperature may impact comfort but not vision, diving experience relates to skills and confidence rather than direct visual ability, and depth could influence light penetration from natural sources but does not directly govern the visibility in the absence of external light sources. Thus, the ability to see clearly during a night dive fundamentally relies on the effectiveness of the lights used.
