– Stereo blindness defined

The condition of stereo blindness occurs when two eyes do not work together to create one 3D image.[1]

Because each eye is in a different horizontal position, each has a slightly different perspective on a scene yielding different retinal images.[2]

In the following example, whereas the main object (dolphin) remains in the center of the two images in the two eyes, the cube is shifted to the right in the left eye’s image and is shifted to the left when in the right eye’s image.[2]

The left eye view shifts the cube in the foreground slightly to the right

The right eye view shifts the cube in the foreground slightly to the left

Normally two images are not perceived, but rather [the brain creates] a single view of the scene.[2]

Binocular fusion or stereopsis and 3D vision

Stereopsis [is] the successful merging of the two slightly different pictures seen in each eye into one 3D image.[1]

The condition of stereo blindness occurs when two eyes do not work together to create one 3D image.[1]

Treatment for Stereo Blindness
Patients with stereo blindness require optometric vision therapy, including the use of prisms and 3D glasses. Treatment duration will depend upon the particular patient’s condition and associated factors.[1]
