The material which contacts are made from is a differentiator. There are two distinct groups of contact lenses, being either hard or soft. Soft lenses are first distinguished by the fact that they are permeable to a degree of gas and secondly by their water content. The water content in soft contact lenses varies from 50% or more, or less than 50%. Hard contact lenses are gas permeable and are made from strong durable materials.

For example, rigid contact lenses have a very long life and can last anywhere from six months to several years.
