Abstract: The measurement of accommodative response is usually performed by means of the Nott method. The accommodative response values were obtained as described in the bibliography and considering that the neutralizing lens shapes the target image. The values in accommodative response differ according to the calculation method utilized. The accommodation and convergence values when the target is placed 40 cm away from the glasses are not the same in emmetropic and ametropic subjects. At the position of the effective binocular object, the initial values are indeed the same for both types of subjects. Comparing with experimental measurements using the Monocular Estimate Method (Mem), it was obtained the same values given the effect of the neutralizing lens. Optimizing the Nott method would require placing the target at a position where the effective binocular object is 40 cm. Furthermore, the effect of the neutralizing lens should be considered in the calculation method.
