DAILY DISPOSABLE CONTACT LENSES

The fastest growing mode of contact lens wear is daily disposable contact lenses.  Traditionally, soft contact lenses have been fit with a two week or monthly replacement schedule.  Cooper Vision, Ciba, Vistakon and Bausch & Lomb are the four major contact lens manufacturers.  Each company has embraced the daily disposable market and there are many fine lenses that our doctors fit.

Advantages of daily disposable contacts

  • New lenses every day
  • No lens care solutions to buy
  • Excellent lenses for non-compliant teenagers
  • Excellent lenses for swimmers
  • Excellent lenses for patients with allergies
  • Excellent lenses for dry eye patients
  • Excellent lenses for occasional wearers

Disadvantage of daily disposable contacts

  • Initially more expensive

Keep in mind the fact that you do not have to buy contact lens care solution makes the overall cost very comparable to two week lenses.  The manufacturers are also very eager to promote the daily disposable lenses and offer substantial rebates.  Let the doctors at Hillsboro Vision Clinic fit you in a week’s worth of these lenses so you can see the advantages before you decide if daily disposables are right for you.

COSMETIC CONTACT LENSES FOR HALLOWEEN

As Halloween approaches the topic of decorative contact lenses always comes up.  Contact lenses are medical devices regulated by the Food and Drug Administration.  A prescription is required to purchase any contacts whether they are tinted or not.  Many street vendors, novelty stores, websites and salons sell decorative contact lenses illegally.

Contact lenses ride on the front surface of your eye, the cornea.  A lens that fits poorly or is used by an untrained wearer can lead to serious eye conditions and possibly blindness.  As eye doctors, we need to see the lens on the eye to determine if the fit is safe.  We do this every day in clinic with diagnostic lenses we have at our disposal in the office.  At one time a large contact lens manufacturer, CIBA, had a product called Wildeyes.  We had diagnostic Wildeyes lenses and could fit and write a prescription for them.  Due to poor sales, CIBA discontinued the Wildeyes line of lenses. 

Because it is somewhat of a fringe product, none of the large contact lens manufacturers are currently making decorative contacts.  The small, niche manufacturers do not have the relationships with the doctors to supply them with the diagnostic lenses for fitting.  So we can’t fit the lens and write a prescription.  This leaves the consumer who wants these contacts in a tough position.  Either go without or get them without a prescription and risk eye injury and infections.  Until something changes and lenses can be fit properly, we recommend leaving these lenses out of your costume plans.

ASTIGMATISM AND CONTACT LENSES

A common misconception we hear in our clinic is that patients believe they can’t wear contact lenses because of astigmatism.  This is simply not true with technology that has been incorporated into today’s contact lenses.

Astigmatism is usually caused by the cornea, the front surface of the eye, being slightly out of round.  Uncorrected astigmatism causes blurry vision and eye strain and can affect near as well as distance vision.  During the refraction process (the part of the vision exam when we ask all those questions about what looks better) we can determine the exact amount and orientation of your astigmatism.  After your refraction, glasses lenses can be ground to your specifications and those lenses are mounted in a frame. Set with your new specs, you’re on your way.

Contact lenses require a diagnostic lens fitting.  Our doctors have ten different brands of contact lenses (toric lenses) especially designed for astigmatism.  Armed with your refraction and a topography of your cornea we choose the lens that we feel will provide the best vision and eye health.  The lenses are placed on the eye and allowed to stabilize for a few minutes and then evaluated for clarity, comfort and fit.  If the first lens does not perform as we would like we try different lenses until we achieve the perfect fit.  In most cases we can send you out the door the first day with either your exact prescription or something very close.

If you are a new contact lens wearer we will train you how to insert and remove the lenses.  You will receive a case, some cleaning and storage solution and we’ll set up a one week follow up visit.  At the follow up we evaluate the success of our initial fit and adjust or change lenses if necessary.  In most cases one or two visits is enough to finalize the prescription.

If you happen to be a patient with very high astigmatism there are custom made soft and rigid contact lenses that are highly successful.  So don’t let astigmatism keep you out of contact lenses.  The doctors at Hillsboro Vision Clinic are experts in fitting patients with astigmatism.  Call us at 503-648-5522 and set up an appointment for a fit today.  Learn more about our clinic at http://www.hillsborovisionclinic.com.
