You know how when you look right at something, like a toy or a book, you can see it really clearly? Well, sometimes when we look at things in space, like stars or planets, they are very faint and hard to see if we look right at them.
That's where averted vision comes in! It's like playing a game of "peek-a-boo" with the stars. Instead of trying to look right at them, we look a little bit to the side, like we're peeking out of the corner of our eye.
When we use averted vision, we can actually see faint objects better. It's like turning up the brightness on a dim light! It works because of the way the cells in our eyes are made. They are more sensitive to light on the sides of our vision, so when we use averted vision, those cells can pick up more light from the faint objects we're looking at.
So next time you're stargazing, remember to use averted vision and play peek-a-boo with the stars!
