Soft, Disposable, Astigmatism & Bifocal Contact Lenses

Whether you need Soft Contact Lenses, Rigid Gas Permeable Contact Lenses, Contact Lenses for Astigmatism, Extended Wear Contact Lenses, Disposable or Planned Replacement Contact Lenses, Specialty Contact Lenses that can change the color of your eye, or Therapeutic Contact Lenses for irregular corneal shapes from keratoconus or scarring, the eye doctors at Duquette Family Eye Care are pleased to offer expert consultation & fitting to help you achieve a safe and comfortable contact lens wearing experience.

Types of Contact Lenses

There are two major categories of contact lenses: Soft Contact Lenses and Rigid Gas Permeable (RGP) Contact Lenses. Regardless of the type of contacts that you are interested in, a thorough examination and fitting are required. Within these two major categories are several types of lenses for solving different vision problems. These include:

  • Soft Daily Wear Contact Lenses
  • Rigid Gas Permeable (RGP) Contact Lenses
  • Contact Lenses for Astigmatism
  • Extended Wear Contact Lenses
  • Disposable or Planned Replacement Contact Lenses
  • Bifocal & Multifocal Contact Lenses for Near Vision Presbyopia
  • Specialty Contact Lenses
    • Scleral Contact Lenses
    • Hybrid Contact Lenses
    • Decorative Non-Prescription Contact Lenses
Soft Daily Wear Contact Lenses

Soft Daily Wear Contact Lenses are made of soft flexible plastics called “hydrogels” that also have water content and allow oxygen to pass to the cornea to maintain its health and clarity. Because they are soft, thin and flexible, Soft Contact Lenses are easier to adapt to and more comfortable than Rigid Gas Permeable (RGP) Contact Lenses. A newer type of Soft Contact Lens is made of a “silicone hydrogel” material that allows an even greater amount of oxygen to reach the cornea than previous soft contact lens, providing additional safety. Soft Daily Wear Contact Lenses require careful cleaning and disinfection, as they tend to attract deposits of protein from your tear film.

Rigid Gas Permeable (RGP) Contact Lenses

Rigid Gas Permeable Contact Lenses (RGPs) are more durable and resistant to deposit buildup, and generally give clearer, crisper vision. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, RGP lenses are not as comfortable as soft contacts and it may take several weeks of adaptation, as compared to only a few days for soft contacts.

Contact Lenses for Astigmatism

People who have astigmatism usually have an unequal curvature of their cornea so that it is shaped more like a football than a basketball. Contact Lenses that correct astigmatism are sometimes called “toric” contact lenses. Toric lenses are readily available in both soft contacts and rigid gas permeable contact lens prescriptions. Toric contact lenses require more intricate fitting sessions and professional expertise to achieve optimal visual acuity.

Extended Wear Contact Lenses

There are a number of Extended Wear Contact Lenses that are available. However, your risk for corneal infection and ulceration increases if you sleep with contact lenses so they are generally not recommended.

Disposable or Planned Replacement Contact Lenses

Today, most soft contact lenses are prescribed with a very specific “planned replacement schedule”. That is, the prescribing eye doctor will give you instructions on how frequently to replace your lenses based on your tear film, how often you may be removing the lenses and how quickly you soil the lenses, even after cleaning and disinfection. True “Daily Disposable” Contact Lenses are worn only once and then discarded; these are becoming the most prescribed contact lens modality due to their safety profile and comfort.

Decorative Non-Prescription Contact Lenses

There is a type of specialty contact lens that are used to change the appearance of your eyes with no need for vision correction. These are sometimes called “Plano”, “Zero-Powered” or “Non-Corrective” lenses. Wearers of these contact lenses will appear to have a different eye color. For example, one can “change” brown eyes to blue and can even create different themes such as Halloween or Dracula by modifying the eye’s appearance.

EVEN THOUGH THESE DECORATIVE LENSES DO NOT CORRECT VISION, THEY ARE A MEDICAL DEVICE AND THE FDA STRICTLY REGULATES THEM .

This is because, even with correction, they pose the identical risks to patients that “regular’ contact lenses pose. These include:

  • Conjunctivitis or Pink Eye
  • Corneal Abrasions
  • Corneal Ulcers
  • Vision Impairment or permanent vision loss

Many patients are simply unaware of the need for proper fitting and prescription of these lenses and have purchased decorative contact lenses from various unreliable sources. Buying contact lenses without a prescription is dangerous and illegal.

Ordering & Refilling Contact Lens Prescriptions

If you are wearing your lenses on a planned replacement basis, when you remove your lenses, ALWAYS make sure to clean and disinfect them properly before reinserting them. This is necessary to protect the health of your eyes and allow you to continue to wear your contacts comfortably and safely. Your doctor at Duquette Family Eye Care will discuss your individual eye health needs and make an appropriate recommendation regarding contact lens wearing schedules.

We offer convenient in-office, online, or over the phone ordering for your contacts that are prescribed by your doctor.  All contact lens orders must have a valid prescription.
