Contact Lenses

Which Is the Right Contact Lens for You?

Your contact lenses should do three things:

1.  properly fit your cornea

2.  give you clear vision

3.  provide any "extra" benefits you desire (or require) such as color, the convenience of daily disposal or multiple powers.

Contact lenses come in tens of thousands of combinations of size, shape and power. That's why contact lenses are a prescription item and must be fitted by an experienced professional. This ensure comfortable fit and great vision.

Our eye care center professional will evaluate your eyes to determine which lens is right for you and will take into account your special needs such as dry eyes, a desire for color change or the need to overnight wear.

About Contact Lenses

Today's contact lenses fall into two categories: soft lenses that are made from water-containing plastics, and GP or "oxygen permeable" rigid contact lenses.

Contact lenses may also be classified by wearing schedule. Daily wear contacts must be removed, cleaned and stored each night, while extended wear contact lenses are made from materials which are safe for overnight wear. Sometimes "continuous wear" is used for a type of extended wear lens that can be worn for up to 30 days.

Contacts can also be described by replacement interval -- that is, how often you discard the lenses and replace them with a fresh pair.

Daily disposable contact lenses are discarded nightly and therefore require no care, cleaning or lens case. Other common replacement intervals are weekly, bi-weekly, monthly or quarterly; any of those lenses can be called "disposable". Traditional, non-disposable lenses are usually replaced once a year, but these lenses are generally limited to unusual or difficult-to-manufacture prescriptions.

Contact Lens Designs

Various contact lens designs are available for different vision problems.

  1. Spherical contact lenses correct nearsightedness and are indicated by a minus or plus in your prescription, respectively.
  2. Bifocal contact lenses are similar to multifocal eyeglasses in that they use different optical zones to correct presbyopia (the age-related, decreased ability to see at both near and far distances).
  3. Toric contact lenses correct astigmatism, which can accompany either nearsightedness or farsightedness.
