About size and frame selection

I – About size selection

There are many different eyeglass sizes and your frame should be fitted by a skilled optician to ensure the best fit, comfort, and appearance.

How can I know what my current size is?

Every pair of glasses is a little different, so the size information may not always be located in the same place. Look on the inside of your current frames. You will find the size information stamped either on the temples or on the bridge:

  • Eye Size: a two-digit number between 40 and 62. It corresponds to the tal width of each lens in millimetres.
  • Bridge width: a two-digit number between 14 and 24. This would be the distance between the two lenses in millimetres.
  • Temple length: a three-digit number between 120 and 150, which corresponds to the length between the screw and temple tips.

When choosing new glasses, the sizes will always be a little different. In fact, each eyeglass frame is unique and as such, several can fit you.

Opticians are trained to help you choose the right size of glasses specific to your eyes and face. But sometimes even the right size of glasses requires an extra adjustment. For example, if your glasses slip on your nose or cause discomfort behind your ears, your optician can adjust the glasses accordingly to achieve the perfect fit.

II – Selecting the right frame

Did you know that the shape of you face can help you choose your new pair of glasses ?

Round face shape

Do you have a round face shape?

What does that mean? Your facial features are seemingly equal in both length and width, plus your chin and jaw have soft, curved angles.

Which frame to choose? Choose frames that are more rectangular in shape and preferably wide to make your face look more slender.

Oval face shape

Do you have an oval face shape?

What does this mean? Here, too, your face is round yet this time your face is longer than it is wide. 

Which frame to choose? You are lucky enough to have a morphology that allows you all shapes and sizes. You just need to choose a frame that goes with your size and that meets all your needs, both in terms of style and optical quality.

Triangular face shape

Do you have a triangular face shape?

What does it mean? Your forehead is wider than your chin. This shape is also commonly referred to as the heart-shaped face.

Which frame should I choose? You can choose a frame with a rather round shape, maybe wide, especially at the lower edges. Rimless frames are also particularly recommended.

Square face shape

Do you have a square face shape?

What does this mean? The lines of your forehead and jaw line up. Your forehead is quite broad and you have a fairly pronounced jaw.

Which frame to choose? To soften the angles of your face, choose round, oval or “butterfly” shapes. Avoid square or overly geometric shapes that might accentuate the width of your face.

Do you have a rectangular face shape?

What does this mean? Your forehead is quite wide and you have a rather pronounced jaw.  The lines of your forehead and jawline are aligned in terms of width, but your face is elongated.

Which frame to choose? The oval and “butterfly” shapes are particularly suitable for your shape, as they would help balance out the length and width. Avoid shapes that are too round and geometric which will make your face look longer.

Whichever shape of glasses you choose, we recommend that for optimum and long-term comfort you also pay attention to the following points:

  • The top of the frame should always be aligned with your eyebrow line. Indeed, your eyebrows should not be seen through your lenses, on the contrary, they should be hidden by the top of the frame. If not, it may unbalance the harmony of your face.
  • Your eyelashes should not touch the lenses: this is not comfortable and will make the lenses repetitively dirty. If this is the case, don’t hesitate to ask your optician to adjust your frame.
  • The bottom of your glasses should not touch your cheekbones, even when you’re smiling.
  • The width of your glasses should be chosen to suit you, and you only. There are different widths of frames precisely to fit all types of faces. When you try on a frame, make sure that the temples do not extend too far apart towards your ears. If this is the case, it means that the frame is too small for your face, and your eyesight may even be impaired. Ask your optician for another size when in doubt.

Should your vision correction be taken into account when choosing your pair of glasses?

Taking your correction into account when finalizing your choice of frame is key. Indeed, if your correction is strong, the lens might be thick (in the centre or on the edges, depending on your vision defect). It is therefore possible that certain shapes or models will not be the best match for your visual needs.

To make sure you aren’t making any wrong choices, always ask your optician for advice: he has the expertise to guide you towards the models that will suit you best. He can also recommend thinner lenses, which will give you a wider range of choices.
