The near point and the far point of vision are fundamental concepts that describe the limits of clear vision at different distances. The near point specifically refers to the closest distance at which the eye can see an object clearly, typically defined as the point where accommodation (the eye's ability to focus) is maximized. For adults, this distance usually ranges between 25 to 30 centimeters, but it can vary based on factors like age and eye health.

On the other hand, the far point indicates the furthest distance at which objects can still be seen clearly without any strain on the eye. In a normally sighted individual, the far point is theoretically at infinity, meaning that as objects move farther away, they remain in focus.

This distinction is critical not just in understanding normal vision, but also in identifying vision problems. For example, if a person has myopia (nearsightedness), their far point is closer than infinity, necessitating corrective lenses for distance vision. Hence, recognizing the near point as the closest distance for clear focus and the far point as the farthest is essential for understanding how the eyes function concerning distance perception and focusing ability.
