understanding and Interpreting Optical Aberrations

Abstract

Recent technological advances make it possible to evaluate visual quality in both an objective and subjective way. It is for this reason that, as visual and ocular health professionals, optometrists must consider the importance of prescribing optical correction based on visual image quantity and quality during their clinical practice, as it determines a quantitative factor, such as visual acuity from the patient’s subjective point of view, and a qualitative factor, such as quality and clarity with which images are seen. Physical optics applied to the human eye creates the possibility of analyzing light wavefronts refracted through the ocular media, making it possible to see the optical behavior of the dioptric system of the eye. Optical aberrations generated by the cornea or the lens are defined as visual system imperfections, therefore producing defective retinal images in the patient and limiting their vision
