How exactly do your eyes work and how can you take good care of them? What is the difference between nearsightedness and farsightedness? How do dry eyes develop? And how do you wear contact lenses safely? Answers to these questions and more can be found on this page.

There are several ways to examine your eyes. An initial exam is often done using an autorefractor.
