What is one way in which glare from the sun can affect a rescuer's ability to see a submerged person?

The choice indicating that glare from the sun can cause distortion in depth perception is accurate because glare can impede a rescuer's ability to judge the distance and depth of objects underwater. When bright light reflects off the water's surface, it can create a wash of light that obscures what lies beneath. This distortion affects how a rescuer perceives distance and may lead to difficulty in identifying the location or condition of someone who is submerged.

Understanding this effect is crucial for lifeguards, as poor depth perception due to glare can slow down their reaction time in emergencies. By recognizing the specific challenges that glare presents, rescuers can take precautionary measures, such as changing their viewing angle or positioning themselves in a way that minimizes the glare's impact, ensuring they maintain optimal visibility during a rescue operation.
