Közelpontja

Közelpontja is a Hungarian term that translates to "near point of vision" or "near point of accommodation" in English. It refers to the closest distance at which an individual can clearly focus on an object without straining their eyes. This ability is dependent on the eye's capacity to accommodate, which is the process by which the lens changes shape to focus light from objects at varying distances onto the retina.

For a healthy young adult, the average közelpontja is typically around 10 centimeters (approximately 4 inches). As a person ages, the elasticity of the eye's lens decreases, a condition known as presbyopia. This leads to the közelpontja gradually receding further away from the eye. Consequently, individuals with presbyopia may experience difficulty reading small print or performing other close-up tasks.

The exact measurement of an individual's közelpontja can be determined through an eye examination. It is a crucial factor in assessing visual function, particularly for tasks requiring fine detail work. Changes in the közelpontja can be an early indicator of age-related vision changes or other eye conditions. Understanding one's közelpontja helps in selecting appropriate corrective lenses, such as reading glasses or bifocals, to comfortably view objects at close range.
