The key is distorting the way light bounces off an object.

关键在于扭曲光线从物体反射的方式。

Or it can enter your eye by bouncing off an object, like this ridiculously large apple.

或者它可以通过物体反弹进入您的眼睛，例如这个大得可笑的苹果。

You see, when light shines off an object, like your face and hits a super smooth surface, the rays of light can all bounce back at the same exact angle.

当光线从物体（例如你的脸）上照射到超光滑的表面时，所有光线都可以以相同的精确角度反射回来。
