Previous studies indicate that a number of individuals display significant differences between astigmatism measured at farpoint and nearpoint. Adventitious effects, purposeful lenticular changes and adaptations in response to environmental forces are reviewed as possible sources of this astigmatic variability.
先前的研究表明,许多人在远点和近点测量的散光之间存在显著差异。文中回顾了偶然效应、有意的晶状体变化以及对环境力量的适应性,将其视为这种散光变异性的可能来源。
