What You’ll Learn

1. What are the key parts of your eye and what do they do?

2. How do human eyes differ from those of animals? Which animals can see further? Or more colors? Or have a wider field of view?

3. If our eyes are so complex and advanced – why do so many people need to wear corrective glasses or contact lenses? 

Your eye is the size of a ping pong ball, but how exactly do your eyes work?  What are the different parts of your eye?  And how do your eyes differ from those of animals?
