We determined the prevalence of prescription glasses-induced prismatic effect among a sample of 100 patients in the Kingdom of Saudi Arabia. All the glasses sampled had a certain degree and type of induced prismatic effect. A small percentage (5%) of the subjects complained about their glasses. Prism adaptation is thought to be the reason why the number of patients complaining about improperly fitted glasses does not reflect the frequency of the problem. Simple ways of eliminating these inaccuracies are suggested.
我们确定了沙特阿拉伯王国100名患者样本中处方眼镜引起的棱镜效应的患病率。所有抽样的眼镜都有一定程度和类型的诱导棱镜效应。一小部分（5%）受试者抱怨他们的眼镜。棱镜适应被认为是抱怨眼镜佩戴不当的患者数量不能反映该问题频率的原因。文中还提出了消除这些误差的简单方法。
