Weban optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrometers are currently the most important tools ... WebOct 9, 2014 · 1) Low Degree Aberrations : It include Myopia, Hypermetropia & Regular Astigmatism.
