Wearable apparatus for correction of visual alignment under torsional strabismus.

Significance: A wearable optical apparatus that compensates for eye misalignment (strabismus) to correct for double vision (diplopia) is proposed. In contrast to prism lenses, commonly used to compensate for horizontal and/or vertical misalignment, the proposed approach is able to compensate for any combination of horizontal, vertical, and torsional misalignment.

Purpose: If the action of the extraocular muscles is compromised (e.
