title: [Pitfalls in the prescription of reading glasses].
abstract: People in the second half of their lives often require reading glasses. A basic requirement for determining suitable reading glasses is measurement of the patient's accommodation, which describes the change in the eye's optical power caused by the attempt to clearly focus on an object at a certain distance. The maximum accommodation performance of a person already begins to decline from the age of 40 onwards. When it becomes increasingly difficult to adjust to the typical reading distance of 40 cm, one speaks of presbyopia: age-related farsightedness. This contribution describes two appropriate methods for determining the strength of reading glasses: determination of the maximum accommodation performance by measuring the near point distance and determination of the maximum accommodation effort by measuring the relative positive and negative accommodation. Optimal reading glasses enable the patient to focus sharply on something from the working distance that is closer but also on something that is further away.
