Q7. What are gas permeable lenses?

A7. This type of lens is less popular than soft lenses but still performs a useful function. In fact, there are cases where gas permeable lenses are better than soft lenses, such as astigmatism or presbyopia.

These lenses are tough and hard wearing and last longer than soft lenses. Plus there are people who find that they give clearer vision than soft lenses.

These lenses are discussed further in our types of contact lenses section.
