The paper investigates the estimation of aberrations in the human eye using pupil scaling techniques. It highlights the significance of accurately measuring eye aberrations, which affect retinal image quality, particularly at larger pupil sizes. The study presents mathematical procedures for estimating Zernike coefficients from measured values at different pupil sizes, emphasizing the importance of standardization for clinical applications.
