The image is formed as a Sturm's conoid.If the principal meridians are at 90° to each other, this is called regular astigmatism. If the principal meridians are at 90° to each other but do not lie at or near 90° and 180°, the term oblique astigmatism is used. If the principal meridians are not at 90° to each other, this is called irregular astigmatism and cannot be corrected by
spectacles.
