Answer 3

Our eyes work best when they are looking through the air.

When we swim underwater water presses against our eyes and it is harder to keep our eyes open. Goggles stop the water touching our eyes so we can see more comfortably.

We see things when light reflects off them and travels into our eyes. The light needs to hit the right place at the back of our eye for us to see a clear image.

Light travels differently through water. The water bends the image so the image gets distorted.

And when water touches our eyes it makes it harder for us to focus and get a clear image.

Goggles allow space for us to focus the image and they also make it easier to judge the distortion from the bending of the image as it travels through the water.

Answer 4

Without google water is in your eyes making your vision blurry. Goggles prevent water from touching your eyes by making an air bubble allowing you to see good.
