The Snellen eye chart was a wonderful invention because people could visit an eye doctor anywhere and get standardized results. Although a lot of progress has been made in medicine since the creation of the Snellen eye chart in 1862, it is still in use today. With this revolutionary chart, doctors can quickly evaluate their patients’ eyesight. A typical eye exam starts with the patient covering one eye and reading the letters on the chart from top to bottom.
史奈侖視力表是一項了不起的發明，因為人們可以在任何地方拜訪眼科醫生，並獲得標準化的測試結果。儘管自 1862 年史奈侖視力表問世以來，醫學領域已大幅進步，它至今仍被使用中。有了這個革命性的視力表，醫生可以迅速評估病患的視力。一般的視力檢查首先會讓患者遮住一隻眼睛，然後從上到下朗讀視力表上的字母。
