Mechanism of accommodation: A review of theoretical propositions

open access: yesAfrican Vision and Eye Health, 2015
Accommodation is the process by which the human eye changes its focus to see objects at varying distances from the eye. For nearly 300 years, scientists have investigated and presented various views on the mechanism of accommodation.

New methodology to measure the dynamics of ocular wave front aberrations during small amplitude changes of accommodation [PDF]

open access: yes, 2007
We present a methodology to measure the systematic changes of aberrations induced by small changes in amplitude of accommodation. We use a method similar the one used in electrophysiology, where a periodic stimulus is presented to the eye and many ...
