What visual condition might require the use of prism correction in spectacles?

Prism correction is primarily used in spectacles to help manage strabismus, which is a condition characterized by misalignment of the eyes. This misalignment can result in double vision or difficulties with depth perception, as the eyes do not work together effectively. By incorporating prismatic lenses into glasses, the visual axes of the eyes can be aligned more closely, helping to merge the images seen by each eye into a single unified image.

This treatment allows individuals with strabismus to improve their visual function and comfort, enabling better binocular vision. While astigmatism, myopia, and hyperopia are refractive errors that can be corrected with lenses that change the focus of light entering the eye, they do not typically necessitate the use of prisms to correct alignment or angle of vision issues. Therefore, prism correction is specifically indicated for strabismus, making it the relevant condition in this context.
