In this lesson you will learn about

1. a) Watch this video to learn about the structures and functions of the structures of the eye. 

b) and watch this video to learn about how light passed through the eye to be focused on the retina. She will talk about some refractive indices (random numbers on things). This is not important for you to know-it is a physics 30 concept. 

c) Watch this video to learn about about defects of the eye. 

2. Once you've watched the video answer the questions from this document. These questions will help make sure that you correctly understand the information from the lesson.

3. Read Chapter 12 pages 406-418 from the textbook for a deeper understanding of this material.
