The quest for the human ocular accommodation mechanism. [PDF]
AbstractWe have known the accommodation phenomenon since 400 BC. Hypotheses about its mechanisms varied widely for two millennia. Early in the 17th century, when people became more aware of ophthalmic optics, Scheiner and Descartes were close to solving that accommodation worked by changes in the lens. Others rejected their idea, and people even denied

Manipulating expectancies in optometry practice: Ocular accommodation and stereoacuity are sensitive to placebo and nocebo effects. [PDF]
There is scientific evidence that an individual's beliefs and/or expectations play a role in the behavioural and physiological response to a given treatment.

Ocular accommodation and wavelength: The effect of longitudinal chromatic aberration on the stimulus-response curve. [PDF]
The longitudinal chromatic aberration (LCA) of the eye creates a chromatic blur on the retina that is an important cue for accommodation. Although this mechanism can work optimally in broadband illuminants such as daylight, it is not clear how the system

On voluntary ocular accommodation [PDF]
Young observers were challenged to induce a marked monocular accommodative response to a relatively weak accommodative stimulus by placing a-9 diopter contact lens on the eye. At first, observers could not produce the desired response, but with training, three of four subjects achieved criterion.

Is Ocular Accommodation Influenced by Dynamic Ambient Illumination and Pupil Size? [PDF]
Purpose: We investigated ocular accommodative responses and pupil diameters under different light intensities in order to explore whether changes in light intensity aid effective accommodation function training.

Seeing the future: Predictive control in neural models of ocular accommodation. [PDF]
Ocular accommodation is the process of adjusting the eye’s crystalline lens so as to bring the retinal image into sharp focus. The major stimulus to accommodation is therefore retinal defocus, and in essence, the job of accommodative control is to send a

Ocular Biometry and its Relation to Amplitude of Accommodation in Normal Subjects [PDF]
Accommodation of the eye defined as changes in the dioptric power of the eye to focus sharply on objects at a range of distances. The maximum potential increase in optical power of eye is known as the amplitude of accommodation [1].

Determining the relative contribution of retinal disparity and blur cues to ocular accommodation in Down syndrome. [PDF]
Individuals with Down syndrome (DS) often exhibit hypoaccommodation alongside accurate vergence. This study investigates the sensitivity of the two systems to retinal disparity and blur cues, establishing the relationship between the two in terms of ...

Customized models of ocular aberrations across the visual field during accommodation [PDF]
We aimed to create individual eye models that accurately reproduce the empirical measurements of wave-front aberrations across the visual field at different accommodative states, thus providing a mechanistic explanation for the changes in the eye's ...
