Monovision correction for diplopia.

Acquired, incomitant strabismus frequently results in diplopia. Affected patients complain of chronic annoyance and frustration with the false image. Therapy has usually been aimed at either re-establishing binocularity by using prisms or vision training, or by eliminating one image through occlusion. An alternative approach is to allow each eye its own "domain," one eye corrected for distance vision and the other for near vision. This alternative may eliminate the competitive, unfusible images and yet maintain visual function in each eye.
