This module explains application of the properties of light to some common optical instruments, the different eye defects, and how lenses correct these defects.
Objective
After going through the module you are expected to:
1. identify the parts of a human eye;
2. discuss the different eye defects and how lenses correct these defects;
3. compare the similarities and differences between the principle of the camera and the human eye;
4. show using ray diagrams how images are formed in a telescope and a microscope; and
