If you suffer from severe astigmatism, your eye doctor may suggest rigid, gas permeable contact lenses. These are often called hard contact lenses, because they are made from an inflexible material. Gas permeable lenses are worn for a full year, and are more resistant to breaking or ripping than soft contact lenses.
Eye doctors more commonly prescribe disposable contact lenses, or soft contact lenses, for vision correction. These lenses are typically worn for one or two months before throwing them away and using a fresh, new pair. They are sold in boxes of six, and you can purchase up to a year’s supply of lenses at one time. Daily wear contact lenses are worn for a full day, and removed and stored while you sleep. Extended wear contact lenses are soft contact lenses that are worn day and night for a week at a time.
