Can you believe everything you see? [A] Not always! Sometimes our minds and our eyes make mistakes. At other times, our eyes and minds can become confused. This may be because we are looking at something called an optical illusion.
The word optical means "related to sight"--the way we see things with our eyes. An illusion is something that looks different from the way it really is. In short, an optical illusion is a kind of trick that our eyes play on us.
Look at these optical illusions and compare what you see with what your classmates see. The way we see things is often personal, so you may not see things the same way as someone else.
So can you trust your eyes? Perhaps the answer is "sometimes." Sometimes our eyes see something, and our minds understand it easily. At other times, we may need to look twice.
