astigmatic
Needing cylindrical lenses
Astigmatic describes eyes or lenses with astigmatism—a defect where light rays fail to meet at a single focal point, causing blurred or distorted vision.
The cornea or lens is curved unevenly, like a football rather than a basketball.
Figuratively, astigmatic can mean having a distorted or skewed perspective: an astigmatic view of history.
