The effective fusional range for words in a natural viewing situation
نویسندگان
چکیده
We investigated the effective fusional range for written stimuli in children and adults in a natural viewing situation. We recorded binocular eye movements in children and adults during processing of stereoscopically presented words in a lexical decision task. The effect of disparity magnitude on ease of fusion caused decreased response accuracy, increasing numbers of fixations and increased trial viewing times when retinal disparity exceeded one character space. The data suggest that retinal inputs of a word that are disparate by up to one character (0.37 degrees) fall within the effective fusional range such that lexical decisions are not impaired.

Effect of Illumination on Ocular Status Modifications Induced by Short-Term 3D TV Viewing
Objectives. This study aimed to compare changes in ocular status after 3D TV viewing under three modes of illumination and thereby identify optimal illumination for 3D TV viewing. Methods. The following measures of ocular status were assessed: the accommodative response, accommodative microfluctuation, accommodative facility, relative accommodation, gradient accommodative convergence/accommodat...

The main objective of this work is to determine the reading performance of operators’ under different viewing angles of a desktop computer. The effects of text/background color, viewing distance and character size on the speed of reading were investigated. The text and/or the background color combination were varied, with constant luminance contrast. Performance was recorded in terms of words p...
متن کاملAcquired central disruption of fusional amplitude.
Acquired central disruption of fusional amplitude is characterized by a complete loss of fusional amplitude, the patient maintaining fusion for only a moment under test conditions before breaking to constant diplopia. Under normal viewing conditions, the patient has constant diplopia with both eyes open. Patients who have bilateral superior oblique palsy may mimic this loss of fusion and consta...
متن کاملNatural strabismus in monkeys: accommodative errors assessed by photorefraction and their relationship to convergence errors.
PURPOSE To examine accommodation and accommodative convergence relationships in naturally strabismic monkeys. METHODS Photorefraction was used to measure accommodative responses of each eye under monocular and binocular viewing conditions. These accommodative results were then compared to assessments of vergence state made under monocular viewing conditions using methods previously described....
