眼镜光学中心水平距离存在偏差,戴镜者将会随着光学中心水平距离同戴镜者眼镜瞳距偏差大小的情况而改变视力清晰程度,重者出现不适感; 眼镜光学中心存在垂直互差,轻者造成戴镜者清晰度减弱,中者造成不适感,重者造成头晕、恶心、呕吐; 眼镜“光学中心水平偏差”和“光学中心垂直互差”都超差时,戴镜者不仅视物不清楚,还会出现头晕、恶心、呕吐,甚至影响戴镜者身心健康。
Optical center optical center there are deviations, wearing glasses will be with the optical center horizontal distance with the glasses lens pupil deviation from the size of the situation and change the clarity of eyesight, severe discomfort; optical center there is vertical difference between each other poor, Light caused by weaker wearing glasses clarity, who caused discomfort, severe cases caused by dizziness, nausea, vomiting; glasses “optical center horizontal deviation” and "optical center vertical difference between each other are poor, wearing glasses not only Things are not clear, there will be dizziness, nausea, vomiting, and even affect the physical and mental health of wearing glasses.
