Understanding How the Human Eye Adjusts to Different Distances

The video explains the power of accommodation in the human eye, focusing on how the ciliary muscles adjust the lens's curvature to change its focal length. This adjustment allows the eye to focus on objects at varying distances. The video also discusses the limits of accommodation, such as the near point and the far point, which define the range within which the eye can see clearly. For a normal eye, the near point is about 25 centimeters, and the far point is at infinity.

What is the role of ciliary muscles in the accommodation of the human eye?

Explain how the curvature of the lens affects the focal length of the eye.

What happens to the lens when viewing distant objects?

Define the term 'near point' in relation to the human eye.

What is the far point of the eye and how does it relate to normal vision?
