Final answer:

Saccades are quick eye movements crucial for focusing on specific details and tracking fast-moving objects, especially in dim lighting conditions.


Explanation:

Saccades are short, abrupt, irregular eye movements made when viewing smaller objects, allowing the eyes to move quickly over and around the target.

These rapid movements play a crucial role in focusing on specific details, such as inspecting pores on your nose or tracking a fast-moving object like a tennis ball.

As scotopic sensitivity decreases with age, night vision and the ability to see in dim lighting are affected, making these eye movements essential for efficient visual function.
