The conversation between human and AI assistant.
How does the human eye focus on on near and far objects?
Can a person's eye adjust its focus quickly between far and near objects?
Yes, it can. This ability is called accommodation, and it is the ciliary muscle that controls it by changing the shape of the lens. The process happens almost instantaneously, usually within a second or two. However, it may become less efficient as we age or due to certain medical conditions.
