What occurs to the eyes when looking at distant objects?

When focusing on distant objects, the eyes undergo a process known as divergence. This means that the lines of sight from each eye move outward, allowing the visual system to properly perceive objects that are far away. This adjustment is part of the eye's accommodation mechanism, where the ciliary muscles relax, leading to a flatter lens shape, which is ideal for viewing distant images clearly.

In contrast, when looking at close objects, the eyes converge, which helps to maintain a single binocular image. The other responses do not accurately describe the behavior of the eyes when focusing on distant objects; remaining converged suggests that the eyes would be turned inward, which is counterproductive for distance viewing. Meanwhile, excessive blinking does not play a role in the process of focusing on distant objects. Thus, divergence is the key physiological response when the eyes are adapting to focus on objects that are far away.
