The Human Eye and How It Works
Cataracts and Lens Function
You can see how many structures and processes are important to the act of seeing. If just one structure is defective or one process doesn't work properly, the eyesight-so important to most of us in almost everything we do-can be damaged. Like other parts of our bodies, our eyes don't function as well when we age as they did when we were young.
Cataracts are the most common age-related eye defect. The next chapter will explain what cataracts are and how they interfere with the intricate function of the lens.
