Light from a single point of a distant object and light from a single point of a near object being brought to a focus. The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size.
Accommodative convergence is that portion of the range of inward rotation of both eyes (i.e., convergence) that occurs in response to an increase in optical power for focusing by the crystalline lens (i.e., accommodation). [1] When the human eye engages the accommodation system to focus on a near object, signal is automatically sent to the ...
Light field displays are one of the best ways to solve the vergence-accommodation conflict. [22] They share features with integral imaging displays. CREAL, a near-eye display manufacturer for AR headsets/glasses, developed a light field display technology that projects the light rays just like they exist in the real world. This way, the virtual ...

Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies. In this, distances vary for individuals from the far point —the maximum distance from the eye for which a clear image of an object can be seen, to the near point —the minimum distance for a ...
Right eye diverging while left eye remains relatively stable – an example of partial divergence. In ophthalmology, divergence is the simultaneous outward movement of both eyes away from each other, usually in an effort to maintain single binocular vision when viewing an object. It is a type of vergence eye movement.

The focussing of each eye, its accommodation, is adjusted so the retinal image of the object is as sharp as possible. This is done via contraction of the ciliary muscles controlling the shape of the crystalline lens of the eye. Although convergence and accommodation are separate processes, they normally operate synergistically. [4]
