it ability to see a sinale image of an object using both eyes.
Essentials for binocular vision
two healthy macula with higher visual acuity tgan any other region at the retina
normally acting set of ocular muscles
efficiency working nervouse mechanism for fusion of the two images whichare slithly dissimilar grades at binocular vision
grade 1
simultaneous perception
grade 2
fusion
grade 3
steroscopic vision
detection of the grades of binocular vision
this can be done by an orthoptic instrument
setroscope and amblyoscop
explnation
grade1
if an object slide is presented to each eye like cow ,the moon and eye see both objects simultaneously.
grade2
it acomposite picture is presented to each eye so that each have of it is incomplete,fusion of the two images occurs and both eyes see one complete image
