Spectacle lenses designed for the modified Listing eye rotation

摘要

Knowledge of the way the eye rotates when changing gaze direction is important for the lens design process. Listing's law of eye rotation conveniently describes that rotation for distant vision. Here, a recently discovered departure from Listing's law in near vision is examined. Although lens designs that accommodate the modified rotations can be produced, as demonstrated here, the benefits to the wearer are unlikely to be perceptible except perhaps in cases of highly astigmatic vision.
