Define distance of distinct vision and provide its range?

The distance of distinct vision refers to the closest distance at which the human eye can clearly focus on an object. This distance is crucial for activities like reading or working on a computer.

Understanding the Range

Typically, the distance of distinct vision is considered to be:

• Near Point: About 25 centimeters (10 inches) from the eye.
• Far Point: The distance at which objects appear clear without strain, generally considered to be infinity for a normal eye.

Importance of Distance of Distinct Vision

This range is essential for ensuring that our eyes can comfortably focus on objects at various distances, which is vital for daily tasks and overall visual health.
