Home » Soft Contact Lenses


Contact lenses are an excellent choice for nearly anyone who needs vision correction and doesn't want to wear eyeglasses full time or undergo LASIK surgery. Soft contact lenses are generally more comfortable to wear. They are able to stay in place better and are easier to adjust to than hard contact lenses. The flexible plastic is combined with water to allow oxygen to pass through the contact lens to the cornea. This increases comfort and maintains eye health.

Soft contact lenses can correct nearsightedness (myopia), farsightedness (hyperopia), blurred vision (astigmatism), and age-related loss of close-up vision (presbyopia).

Soft lenses are made from gel-like, water-containing plastics called hydrogels. These lenses are very thin and pliable and conform to the front surface of the eye. Introduced in the early 1970s, hydrogel lenses made contact lens wear much more popular because they typically are immediately comfortable. The only alternative at the time was hard contact lenses made of PMMA plastic (see below). PMMA lenses typically took weeks to adapt to and many people couldn't wear them successfully.

Silicone hydrogel lenses are an advanced type of soft contact lenses that are more porous than regular hydrogel lenses and allow even more oxygen to reach the cornea. Introduced in 2002, silicone hydrogel contact lenses are now the most popular lenses prescribed in the United States.

Different Types of Soft lenses

  • Disposable Soft Lenses

    Designed to be worn for a short time, disposable contact lenses are great for people with allergies and those who are concerned about getting eye infections from the build-up of bacteria and dirt under the lens. Disposable contact lenses require minimal cleaning and disinfection before being discarded. Today’s soft contact lenses are available as non-disposables, monthly or weekly disposables, and daily disposables.

  • Daily Wear & Extended Wear

    Soft contact lenses are also available for extended and daily wear. Daily wear contacts are intended to be worn during the day and removed for nightly cleaning and disinfecting. Daily wear lenses can be reused until their intended discard date.

    Extended wear soft contact lenses can be worn while sleeping, but must be removed for cleaning and disinfecting once a week. Overnight use may pose a risk of eye infections so caution should be used even with lenses that are designed for extended wea
