영문 초록

Aberration refers to a phase difference in light caused by a variation in the refractive power. Zernike polynomials, the most widely used method for analyzing aberrations in the human eye, consist of various polynomials configured according to the radial order and angular frequency. Among them, aberrations with an angular frequency of zero are suppressed by pupil and retinal sensitivity. Contact lenses for correcting presbyopia have mechanisms that induce vertical coma or spherical aberration. Positive spherical aberration is induced after wearing Ortho-k lenses.
