She was counselled that the prescription may not be the total solution and that she might need a further increase to the prescription of her spectacles and vision training to help re-establish binocularity.
Initially, in the mid-1910s, monocular optometers were used as opposed to phoropters binocular refracting devices that could also measure ducitons, phorias and other traits of binocularity. Phoropters are either made with plus or minus cylinders.
In terms of binocularity, comparison of Worth 4-dot test and near and distant fusion test results showed that fusion was present in 15 (55.6%) patients with strabismus and 24 (63.2%) patients without strabismus, but the difference was statistically nonsignificant (chi-square test, p=0.538).

This open field of play destabilizes conventional reading habits, requiring readers to master a new kind of "double-vision" (Gardner 2006, 801) or "visual-verbal binocularity" (Hirsch 2004, 966) in which they follow both the linear narrative laid out by words and images in sequence and the panoptic or tabular totality of the page's overall design.
There was no statistically significant difference between the groups in pair comparison after adjusting for age and binocularity. The diagnostic performance of estimated RGC count, RNFL thickness, and SAP MD was significantly different in the eyes with SAP MD [greater than or equal to] -6dB (0.92, 0.82, and 0.60, resp.; P = 004).
An unbalance of the ORS between pairs of eyes might lead to problems with the development of binocularity. This has been detected in humans [26], horses [7], and monkeys [12], among others.
Functional vision refers to a variety of specific functions of the eye and the neurological control of these functions such as binocularity, pursuit, saccades, accommodation, convergence etc., while perceptual vision refers to understanding, identifying and judging the importance of what you see.
The association between anisometropia, amblyopia, and binocularity in the absence of strabismus.
Raven's formal conceit joins the famous "separation shot" from Jean-Luc Godard's Adieu an langage (Goodbye to Language, 2014) in staging "bad" 3-D in order to foreground embodied binocularity. One's eyes work hard to resolve the 3-D image before and after the slides perfectly overlap, resulting in a sensation of optical misalignment and pain that serves as a corporeal metaphorization of the occluded labor of production.
Binocularity in refractive accommodative esotropia.
Most visual functions achieve adult levels within the first few months (e.g., contrast, motion, and orientation sensitivity) or the first few years (grating acuity and binocularity) of postnatal life.
