Your eyes are something that you probably don’t give much thought to – as long as they’re working properly. They may only be about the size of a ping-pong ball, but your eyes are among the most amazing parts of your body.
Every moment that you’re awake, your eyes are in constant motion – gathering vast amounts of visual information and helping you make sense of the world around you. They also help communicate your emotions to other people – not bad for two blobs of jelly that each weigh about 8g (about the same as two credit cards).
