An alternative method used since 1940 ( Revell, 1971 ) is to employ free-space fusion. Notwithstanding the method of dissociation, there appear to be two schools of thought regarding the most effective type of exercise. So, to get yourself familiar with this disorder, you are requested to proceed reading further. Stimulus parameters can be varied, for example, by using different target types and sizes. Things like poor sleep quality/quantity, stress, and sickness can exacerbate symptoms of binocular vision dysfunctions. Feinberg DL, Rosner MS, Doble JE. Normally, both eyes match each other in alignment. Fusional reserves can be used to assess the outcome, but the reserves to blur point were so inconsistent they were unusable ( Horwood & Toor, 2014 ). A study, somewhat limited by excluding participants with binocular vision anomalies, found that methods that exercise convergence and accommodation independently are most effective ( Horwood & Toor, 2014 ). The treatment present to correct this disorder involves a unique pair of prism glasses, prism contact lenses, or multifocal contact lenses that allow the eyes to rotate into the position with which they are comfortable. This may support the clinical observation that when exercises are carried out under more natural free-space conditions, improvements in visual function are more likely to translate into everyday life. As time passes, symptoms will only feel worse. DOI: 10.3109/02699052.2015.1113564, Borish IM. Standard vision screenings are insufficient for diagnosis of VH, as they only check for 20/20 vision.
