Contact Lenses Q&A

What is a Contact Lens?

Contact Lenses

A contact is a thin, curved lens that sits on top of the film of a person’s eye, resting on a layer of tears. Contact or optical lenses improve an individual's vision. Lenses are basically clear, except for a light tint that enables wearers to see the lenses while inserting and removing them. Lenses are made of both hard and soft materials, but soft lenses are substantially more popular.

What Types of Contact Lenses Are Available?

Contact lens are most often used for vision correction, however lenses are also available that allow individuals to chance the look of their eye color, purely for aesthetics. All contact lenses are regulated by the Food and Drug Administration and require a prescription. Contacts can be made from different materials including:

  • Hard Lenses = These are constructed of a hard plastic but are pretty much obsolete today.
  • GP Lenses = These are fabricated from waterless, rigid plastics, and allow for the flow of oxygen. GP lenses are best for people with astigmatism. They offer sharper vision than soft lenses.
  • Soft Lenses = These are fabricated from a gel-like plastic known as a hydrogel and cover the entire cornea. Silicone hydrogel lenses are an advanced, innovative type of soft lens that allows for increased oxygen flow.

How Long Do Contacts Lenses Last?

Even with proper care, contact lenses must be replaced frequently to prevent the build-up of deposits and minimize the risk of contamination. Soft lenses are offered in different versions, according to the duration of time they can safely be worn. These include:

  • Traditional- these are designed to be used for 6 months then thrown away
  • Frequent Replacement- these last for 30 days or they can be quarterly
  • Disposable- these are discarded every 14 days, sometimes more frequently
  • Daily- these are thrown away each night and should only be worn once

Gas permeable lenses, or lenses which allow more oxygen through them, can last a lot longer because they are not as susceptible to deposit accumulation. GP lenses can last 12 months or occasionally longer.
