The water content is usually categorized in this way: lenses with a water content of less than 38% are called low water content lenses, lenses with a medium water content between 42% and 60%, and lenses with a high water content greater than 60%.

Long-cycle contact lenses, such as annual disposable lenses, are generally low water content because the water content is maintained by the wearer's tears, whereas short-cycle contact lenses, such as daily disposable lenses, are higher water content because they are more comfortable to wear initially.
