The near point of the eye for a young adult with normal vision is typically around 25 centimeters (10 inches). To maintain comfortable and distinct vision, objects should be held at this distance or farther. Holding objects beyond the near point allows the ciliary muscles to accommodate, adjusting the curvature of the eye lens for optimal focusing on close-up tasks. This distance may vary slightly among individuals, but generally, it represents the point at which the eye can comfortably focus on near objects without experiencing strain or blurriness, ensuring clear vision for activities like reading or using electronic devices.
