How do I know what size contact lenses I should wear?

Contacts come in various "curves," called base curves and this will help determine how the lens fits. But, there are other factors, including the size of the lens and its hydration that determine fit. For example, some lenses have more water in them than others, and may, or may not, dry out more on the eye. This could vary the fit.
