amplitude of accommodation

It is likely that they do not change the amplitude of accommodation to postpone or delay presbyopia.

The amplitude of accommodation declines with age.

Amplitude of accommodation (AA) is a measurement of the eye's ability to focus clearly on objects at near distances (i.e. accommodation).

This explains why the aspect ratio of a vertebrate crystalline lens can be used to predict the qualitative amplitude of accommodation of the vertebrate eye.

The decline in the amplitude of accommodation eventually results in the clinical manifestation of presbyopia As the equatorial diameter of the lens continuously increases over life, baseline zonular tension simultaneously declines.
