Eye Illusion
眼睛的錯覺
眼睛的錯覺
文: 陳瑩
法國國旗之設計原為紅、藍、白三色，各估百分之33.3，其後因人眼目的錯覺，總覺紅色太少，藍色太多，故經由色彩學及光學專家再按色明度之深淺調整為紅色佔全旗面積百分之37，藍色佔百分之33，白色佔百分之30，色澤之寬度不等，但視覺卻得到平衡。這證明人的眼常有錯覺。一條由上而下的垂直線劃在黑板上，若祇憑肉眼測量，把它等分為二，十之八九下半截比上半截長出幾吋，但視覺卻感覺到平衡，反之用尺去等分，反而有上多下少之感。故繪畫的構圖與文字的構造亦要遷就我們的視覺，例如「呂」字，「森」字等，我們看起來才舒服。這當然與環境有關。大自然的一切東西，多是上輕下重，乃因地心吸力的緣故，在此不想深談。人不單肉眼有錯覺，心眼也經常有錯覺。人總喜歡憑自己的喜惡感覺看上帝，看教會，看人。大家仍舊祇根據自己的興趣去思想，去行動，自以為不錯，事實上錯得離譜。人若不真的謙卑下來，決不會明白聖經，若不肯拋棄一些「似是而非」的推斷，決不能與神有所交通。
Eye Illusion

The design of French national flag was originally red, blue and white, each with 33.3 percent of area on the flag. But due to the illusion of human eyes, people always felt that the red color was too little and the blue color was too much. So based on the brightness of the shades, chromatic and optical experts adjusted the red area to 37 percent and blue area to 33 percent, while white area accounts for 30 percent. The width of colors differs but the vision is balanced. This proves that the human eyes often have illusion. Drawing a vertical line on the blackboard, and if you divide it into two equal parts only by the measurement of naked eye, most likely the lower half will be a few inches more than the upper half, but the visual feeling is a balance. On the other hand, if we use a ruler to get the exact equal portions, there will be a feeling that the upper half is more than the lower half. That's why the construction of painting and the composition of Chinese character have to accommodate our vision, for example, the composition of Chinese character "吕" and "森" will make us feel comfortable. This is of course related to the environment. All things in the nature are mostly light on the upper part and heavy on the lower part, which is due to the gravity. Here I do not talk about it in depth. People not only have misconception by the naked eye, but also often have the wrong impression by heart. People always like to feel God as well as see churches and other people according to their own likes and dislikes. We still only think and act in accordance with our interests, believing that's good in our own conceit. In fact, it is glaringly wrong. If we do not become really humble, we will never understand the Bible. If we refuse to abandon some "plausible" deduction, we will never communicate with God.
