Abstract: The invention relates to the determination of higher-order aberrations of an optical element over an optical zone that is larger than the typically limited measured zone over which the aberrations are measured. This is accomplished by apparatus, systems, and methods in which, preferably, the Zernike data from an aberration measurement is fit to a conic function. The conic function smoothly and continuously increases or decreases between the measured zone and the optical zone allowing the extrapolated data to accurately determine the aberrations over the optical zone. According to the invention, a plurality of independent conic plus piston sections that vary azimuthally can very accurately describe a wavefront aberration composed of defocus, astigmatism, spherical aberration, secondary astigmatism, and tetrafoil. The description of primary coma and trefoil will not be as good because they vary with the 3rd order of the radial component. However, the description error is relatively small.

Abstract: Noncorrective protective eyewear with lateral wrap and pantoscopic tilt introduce prismatic distortion and astigmatism into lenses that interfere with good optical performance. The lenses of this invention have an optical axis that is deviated away from the line of sight, in a direction generally opposite the inward tilt of the lateral wrap and/or the incline of pantoscopic tilt, to offset the tilt induced prism. Low power may be introduced into the lenses to decrease their taper, further offset the tilt induced prism and astigmatism (particularly in peripheral fields of view), lessen weight, provide better physical stability, and allow more uniform light transmission than plano lenses. The lenses may be cut from lens blanks in which the A line of the lens is at a non-zero angle to an equator of the lens, and the optical center of the lens may be horizontally and vertically displaced from the geometric center of the lens, and even off the lens altogether.
