Why would being shortsighted and suspicious make a bear dangerous to people?

Being shortsighted and suspicious can make a bear dangerous to people because it may lead the bear to react defensively or aggressively when it perceives a human as a threat. Shortsightedness can limit the bear's ability to assess situations accurately, causing it to feel cornered or provoked even in non-threatening scenariOS. This combination of fear and misinterpretation of human behavior can trigger an attack, as the bear may not recognize that people are not a direct danger. Ultimately, such traits can increase the likelihood of conflict between bears and humans.
