Dear Patients,

Both offices are now open and In order to avoid crowding and to stay on top of additional disinfection procedures, appointment slots will be limited. What you can expect:

  1. Face coverings required, non-touch temperature reading, hand washing upon arrival.
  2. Disinfection of touch surfaces in addition to our usual sanitation procedures as well as barrier films on certain high-touch areas.
  3. Digital frame measurement technologies for all spectacle orders to replace face-to-face measurements.
  4. On-site, but non-facing payment options.
  5. Elimination of paper and electronic forms in the office.

Your cooperation in completing medical questionnaires at home, prior to your visit, is greatly appreciated. Also while we welcome patients along with one guardian when needed, additional friends and family members who do not have an appointment may be asked to wait outside. We’re all excited to see you soon.

Soft vs. RGP Lenses

Below is a brief comparison of Soft and Rigid Gas Permeable (RGP) contact lenses. A thorough eye examination and a better understanding of your specific vision requirements will help determine the best options for you.

Soft Contact Lenses
Advantages



  • Greater initial comfort than hard or rigid gas permeable (RGP) lenses.
  • Shorter adaptation period for new wearers.
  • Ideal for intermittent wear.
  • Less susceptible to the intrusion of foreign objects under the lens, such as dust.
  • Less sensitivity to light than with hard or RGP lenses.
  • Rarely fall out of the eye, making them ideal for sports, particularly contact sports such as football or basketball.
  • Available in tinted versions.

Disadvantages



  • Less durable than hard or RGP lenses.
  • May dry out, causing discomfort for some, especially under a hair dryer, in hot rooms, or in windy, dry weather.
  • More involved lens care, especially for conventional soft lenses.
  • Susceptible to more protein or lipid deposits, that reduce lens performance in the long term.
  • May absorb chemicals from the environment, which can cause irritation.

Rigid Gas Permeable (RGP) Lenses
RGP lenses are, as the name implies, rigid, but the plastics of which they are made are somewhat more flexible than hard lenses. Newer RGP lenses offer the advantage of allowing more oxygen to pass through to the eye. Sometimes they are referred to as “Oxygen Permeable Lenses”. They are available in daily wear and extended wear options.


RGP lenses have the following advantages and disadvantages:


Advantages



  • Good vision.
  • Correct most corneal astigmatism.
  • Good durability.
  • Good handling characteristics.
  • Easier care.

Disadvantages



  • Less initial comfort than soft lenses.
  • Longer adaptation period required than soft lenses.
  • More easily dislodged.
  • Can scratch and break.
  • Intermittent wear less feasible
