Workers
wear them. Swimmers wear them. Scientists wear them. Woodcutters wear them.
People who play sports wear them. Goggles protect the eyes. They keep out water
and chemicals. They keep out bits of wood or stone. They might look funny, but
goggles do serious work!
Why
do people need to wear goggles? They need to keep the can hurt our eyes. Have
you ever gotten a piece of sand or dirt or other small particle in your eye?
What happens? It hurts. Your eye begins to fill with tears. Those tears are
your body's way of getting the sand or dirt out of your eye. Sometimes this
works. Your eye feels much better.
But
what happens if your tears don't work? What happens if the piece of sand has
gotten stuck in your eye? Eyes are delicate.
They can be scratched or cut easier than skin(皮肤). If
the particle is not washed out by tears, you might have to go to the doctor.
You could even have problems seeing out of that eye.
Instead
of waiting to see if tears will help, some people use goggles. This can prevent
things from getting in their eyes at all. If they use goggles, their eyes are
protected from the things that can cause problems. Goggles are a better way to
protect eyes. They are made of plastic or glass, and they are tied around your
eye area. Some of them hook behind your ears like glasses. Other goggles have a
strap (带子) that goes around your head. Both kinds stay right where you put
them until you take them off. That way, you can use both hands to work or play sports,
and you don't have to worry about something getting in your eyes.
Your eyes are safe, and you can get busy
working or playing!
