Mom always told us we'd go blind if we read in the dark. Does science back her up? Jim Sheedy, a doctor of vision science and director of the Vision Performance Institute at Oregon's Pacific University, sets his sights on the truth. 妈妈总是告诉我们如果我们在暗处看书会弄坏眼睛。这种说法有科学依据吗？且听俄勒冈太平洋大学(Pacific University)视觉功能学院(Vision Performance Institute)所长、视觉科学医生吉姆?希迪(Jim Sheedy)为我们揭示真相。 Dark Matter 暗处阅读 Turns out, our parents were wrong. 'There is no reason to believe nor evidence to support that any long-term damage to the eyes or change in the physiology to the eyes can be caused by reading in the dark,' Dr. Sheedy says。 原来，我们的父母是错的。希迪博士说：“我们没有理由认为，也没有证据证明，在暗处阅读会造成眼睛的长期损害，或引起眼睛的生理变化。” That is not to say that nocturnal page-turning won't lead to discomfort or fatigue。 但这并不意味着在夜间昏暗光线下看书不会引起不适和疲劳。 The lack of light will cause the pupils to dilate, resulting in a smaller depth of field -- the distance between the nearest and farthest object that the eye considers to be in focus. Dr. Sheedy says the added effort to change focus (called the eye's accommodative system) and the effort to change the angle of the lines of sight between the two eyes (called the vergent system) will likely make your eyes feel tired and your body spent. But, of course, that's often the object of reading under the covers。 |
