The possibility of the distance refractive type-emmetropia, hypermetropia or myopia-influencing the magnitude and rate of change of the presbyopic add does not seem to have received systematic consideration. To address this possibility a further series of transverse clinical data on the progression of the presbyopic add is presented. Analysis of these data reveals the influence of the distance refractive type on the presbyopic progression. Hypermetropes appear to show a two-phase rise in add requirement whereas emmetropes follow a linear and myopes a curvilinear path over the four decades between 41 and 80 years of age. Nevertheless the magnitude of the binocular add requirement at a given age for each of the three refractive types is very similar and all three classes maintain an increasing requirement with advancing age.
远距离屈光类型（正视、远视或近视）影响老视附加度变化幅度和变化速率的可能性似乎尚未得到系统研究。为了探究这种可能性，本文呈现了关于老视附加度进展的另一系列横向临床数据。对这些数据的分析揭示了远距离屈光类型对老视进展的影响。在41至80岁的四十年间，远视者的附加度需求似乎呈两阶段上升，而正视者呈线性变化，近视者呈曲线变化。然而，在给定年龄，这三种屈光类型的双眼附加度需求幅度非常相似，并且随着年龄的增长，所有三类人群的需求都持续增加。
