Treatment
It is possible to change eye dominance by actively suppressing the visual field of the dominant eye. This is achieved with an eye patch bandage that covers the dominant eye, with adhesive tape around the patch perimeter.
The eye patch does not need to be black to blot out all light, and the dominant eye does not need to stay closed. The eye patch simply presents the dominant eye with a static unchanging visual field containing nothing of visual importance, and the brain is forced to rely on the suppressed eye for visual information.
The experience does cause irritation and frustration for the eye patch wearer since their visual capabilities for comprehension will be reduced until the brain starts to adapt to not being able to use the dominant eye.

Famous quotes containing the word treatment:
“Our treatment of both older people and children reflects the value we place on independence and autonomy. We do our best to make our children independent from birth. We leave them all alone in rooms with the lights out and tell them, “Go to sleep by yourselves.” And the old people we respect most are the ones who will fight for their independence, who would sooner starve to death than ask for help.”
—Margaret Mead (1901–1978)
“Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance.”
—Susan Sontag (b. 1933)
“Ambivalence reaches the level of schizophrenia in our treatment of violence among the young. Parents do not encourage violence, but neither do they take up arms against the industries which encourage it. Parents hide their eyes from the books and comics, slasher films, videos and lyrics which form the texture of an adolescent culture. While all successful societies have inhibited instinct, ours encourages it. Or at least we profess ourselves powerless to interfere with it.”
—C. John Sommerville (20th century)
