Choosing your Eyewear


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.

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.


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.


When you first put on a pair of glasses, it should feel comfortable.

  • 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 comfortable on your face and nose bridge.

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

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


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


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 being worn by the patient.
