About Binocular Prisms
Sometimes called yoked prisms, binocular prisms are used by developmental optometrists to treat some types of visual problems. Not only do the prisms work to shift where an image seems to be located, they force the person wearing them to make a visual adjustment to cope with the distortion. Often the binocular prism has an effect on the person’s posture and balance. That is why they may be a helpful tool for persons on the autism spectrum who tend to hold their eyes in a downcast posture. The binocular prism can be oriented so that the eyes look upward.
