Accommodation is at its peak in childhood and decreases over the years, typically first becoming noticeable when one is in one's 40's. Loss of accommodation is called presbyopia and is what causes people to need reading glasses or multi-focal lenses (or, for short/nearsighted people, simply to take off their glasses in order to read).
The inevitable loss of accommodation (presbyopia) is directly relevant to laser eye surgery in that as a result, it is impossible to correct an eye both for distance vision and for near vision simultaneously in a presbyopic individual. |
