This document discusses several optical illusions and how they demonstrate poor communication between the eyes and brain. It begins by explaining that optical illusions cause us to see things that don't exist or not see things that are there. It then provides examples of different types of optical illusions, including images that appear to spin or change size and hidden 3D images. It concludes by stating that even simple illusions using mirrors can be beautiful by demonstrating what the brain perceives versus what is really there.

2. Forewords
Eyes allow us to experience the world and tell the brain what is going on around us.
But what happens when our brains can't understand what our eyes see?
"Optical illusions" cause poor communication between the eyes and the brain, and
we see things that don't really exist, or can't see things in front of us.
The next are some examples of amazing illusions...
前言
睛讓我們能夠體驗世界，並告訴大腦我們周圍發生了什麼。
但是當我們大腦，無法理解眼睛所看到的東西時，這會發生什麼呢？
「視錯覺」會造成眼睛和大腦之間溝通不順暢，我們會看到不真實存在的東西，或者
看不到面前的東西。
接下來是一些令人驚奇的錯覺例子...。

Magic Eye illusions
魔眼錯覺

30. 「魔眼錯覺」(Magic Eye illusions) 的正式名稱為「立體圖像」或「3D錯覺」。
從技術上講，它是隱藏在 2D 圖形中的3D插圖。
並非每個人都能找到 魔眼圖形 中的隱藏圖片。
如果你真的被難住了，請嘗試接近圖片，專注於一點。保持專注該點，眼睛從屏
幕慢慢向後移動。
Magic Eye illusions are officially known as stereograms, or 3D illusions. Technically, it is
a 3D illustration hidden within a 2D graphic.
Not everyone can find the hidden picture in a Magic Eye graphic.
If you're really stumped, try getting really close to the illusion, and focusing on one point.
Slowly move backwards from the screen, and keep focusing on the one point.

31. Mirror Illusion

And last but not least, the simplest illusions
