There is a special moment in everyone’s life when they receive their first eye exam and discover whether or not they will need to wear glasses. Some people feel relieved to learn that their vision is good. For others, it marks the beginning of life with glasses, which provide clear vision and make everyday tasks much easier. In the past, doctors did not always have an effective method for testing their patients’ vision. The current system was developed around the time of the Industrial Revolution, when more and more people started working in factories. Many workers found that their vision was sufficient for tasks at home but not sharp enough to perform factory work, which required precision.
每個人一生中都有一個特殊時刻，就是接受第一次的視力檢查，並得知自己是否需要戴眼鏡。有些人聽到自己視力良好時會鬆一口氣。對其他人而言，這標誌著戴眼鏡的人生開端，眼鏡能賦予清晰的視力並讓日常事務變得更加輕鬆。過去，醫生並不總是有個有效的方法來測量病人的視力。目前使用的系統大約是在工業革命時期發展出來的，當時越來越多人開始在工廠工作。許多工人發現，他們的視力足以應付家事，但對於需要精準度的工廠工作來說，卻不夠清晰而無法執行。
