Comfort


There are four main things to consider when you pick out your glasses.

  • The eyes are centered in the frames.
  • The frames are not sitting on your checks when you smile.
  • The frames are not pinching the side of your head.
  • Your eyelashes are not touching the lenses in the frames.
  • The frames sit comfortably on your face and nose bridge.

Color


Before deciding what frame color will work best with your eye color, ask yourself whether you want to stand out, or blend in.

  • Lean toward frames that contrast with the tone of your face or hair.
  • People with white or blonde hair should try a darker shade.
  • People with dark hair should try a slightly lighter shade than their hair color.

Face Shape


The old rule—the frames of your glasses should contrast with the shape of your face—is still valid.

  • Round face should try an angular frame.
  • Long narrow face should try a circular frame.
  • Oval face should try a circular or square-off frame.

Lifestyle


Glasses can now be made to fit all your hobbies, sports, and special needs. These days, the glasses are made to adapt to your lifestyle needs versus the other way around, where you have to adapt to the glasses.

CHOOSING YOUR LENSES

Our skilled opticians will help you choose the perfect pair of glasses for you.

Lens Material


Few lenses are made of glass because plastic lenses are lighter, thinner, and less likely to shatter. Due to today’s technology, lenses are made digitally by using:

  • Plastic CR-39
    • Basic plastic lenses. Glass lenses are rarely-used.
  • Polycarbonate
    • Essilor polycarbonate lenses are 20% thinner, 30% lighter, and 12x more impact-resistant than standard plastic lenses; making it great for safety glasses for work and sports.
  • Hi-Index
    • The higher than index number, the thinner the lens will be. The highest index we have available at GVO is 1.74.

CHOOSING THE RIGHT FIT

There are 4 measurements that are needed to make sure your glasses fit properly.

PD (Pupil Distance)


PD refers to the distance in millimeters between the center of one pupil to the center of the other.

Pantoscopic Tilt


Corresponds to the tilt of the frame in relation to the primary horizontal direction of gaze.

Wrap


Frame wrap angle describes the horizontal angle of the lens plane in front of the eyes.

Vertex


Vertex distance is the distance from the front surface of the cornea to the back side of a lens that is mounted in a frame and worn by the patient.
