      Soft contact lenses were originally designed to be worn for 12 to 18 months away and overnight stays. Soft contact lenses have been published in many different formats, since they were first developed in the 1960s.These soft contact lenses are now called “traditional contact lenses.” They are usually prescribed as a specialty lens and are typically used when frequent replacement or disposable contact lenses are not available. They have the disadvantage of being expensive and tend to accumulate superficial deposits. This type of lens wear requires more care, cleaning and maintenance products. Disposable contact lenses were first released commercially in the 1980s. The first available lens was the Johnson & Johnson Acuvue contact lenses, which had a 2-week disposable contact lenses.

Both lenses are extended wear for a month were approved. Silicone hydrogel contact lenses have the advantage of a higher oxygen permeability then the original hydrogel contact lenses. Approximately 98% of patients are able to wear this type of contact lenses. However, there is a slightly increased chance of developing microbial keratitis or corneal ulcer with this type of wear. Some studies put the risk at one of five hundred years per carry.

The next generation of soft silicone hydrogel lenses saw the release of O2 Optix Ciba and Johnson & Johnson Acuvue Oasys. These lenses have an improved surface treatment, which leads to improved hydration and comfort.More recently, soft hydrogel contact lenses days are becoming increasingly popular. These lenses, like J & J 1-Day Acuvue Moist Focus Dailies Cibavision and have the advantage of being more hydrophilic and hold moisture during the day.Focus Dailies contact lenses to improve AquaRelease contain fluid and are exchanged daily, leading to an increased comfort and a clean lens.
