ISO 10944:2009与ISO 15004-1一起规定了用于测试、测量、训练和发展患者双眼视觉以及测量不同注视位置的水平、垂直和循环偏差的同视机(也称为主要弱视镜或同视计)的最低要求和测试方法。
如果存在差异,ISO 10944:2009优先于ISO 15004-1。
ISO 10944:2009, together with ISO 15004-1, specifies minimum requirements and test methods for synoptophores (also called major amblyoscopes or synoptometers) used to test, measure, train and develop the patient's binocular vision and to measure horizontal, vertical and cyclo deviation in different positions of gaze.
ISO 10944:2009 takes precedence over ISO 15004-1, if differences exist.
