 '''Accommodation''' is the ability of the healthy eye to focus on both near and far objects.  The relaxed state of the [[ciliary muscle]] is distance vision, and the flexed state is near vision.
-=Presbyopia=
+As you age, the lens in your eye becomes less flexible, resulting in [[presbyopia]].
-As you age, the lens in your eye becomes less flexible.  This makes accommodation more difficult and brings on "arms are not long enough to read" symptoms.  Someone may be both [[myopic]] and presbyopic, and have deficits in both near and far vision.  Your [[Prescription]] will have an "Add" section specifying bifocals or multifocals if you have diagnosed presbyopia, or if your doctor thinks it best to reduce eye strain.
-==Bifocals==
-Glasses with a lower section that is specifically for close work.
-==Multifocals==
-Contacts that have sections for near and far work, which the [[visual cortex]] will selectively use when looking at different distances.
