O+ FIT GUIDE

A frame should sit well before it says anything.

Fit starts at the bridge. Then it moves across the front, and settles behind the ears.

The numbers help. The way a frame rests on your nose, clears your cheeks, and holds through the day tells you more.

Real faces. Different bridges. Different balances. O+ ARCHIVE

START WITH THE NUMBERS

A size is a clue, not a verdict.

Two frames can share similar numbers and still feel different. Bridge shape, rim depth and overall width do most of the work.

READ THE FRAME

Three numbers. Four things to notice.

There's a part of every frame most people take for granted: the bridge. It does more work than it gets credit for. Overall width is not always printed on the arm, but it often explains why one frame feels broader than another.

LENS WIDTH BRIDGE TEMPLE / ARM OVERALL WIDTH

Lens width Scale of one lens, not the whole frame.

Bridge The gap between the lenses, and the shape that rests on your nose.

Temple Arm length to the bend. It affects hold behind the ear.

Overall width End to end across the front. Often the reason one frame feels broader.

WHAT THE SIZE MISSES

Similar numbers, different presence.

Brando

Deeper acetate rim. More presence around the eyes.

Harlow

Rounder line. Lighter edge around the face.

The point is not to find the smallest or largest number. It is to understand what the frame does with it.

THE SAME FRAME, READ DIFFERENTLY

One shape. Three faces.

The measurements stay the same. What changes is the relationship between the frame and the face.

Notice where the bridge rests, where the eyes sit within the lenses, and how much width the frame carries at the sides.

WHAT TO NOTICE Use these as references, not fixed categories.

At the bridge Where the frame rests and whether it appears level.

At the eyes Where each eye sits within the lens opening.

At the outer edge How much frame extends beyond the face.

At the temples Whether the arms open, press or remain parallel.

Shown in Wells across three colourways. The frame is the reference; individual fit still depends on the bridge, eye position and temple width.

HOW DOES THE FRAME SIT ON YOU?

A two-minute fit check.

Use the pair you reach for most.

It gives you a better starting point than a generic small, medium or large label. Look at how the frame behaves, not only what is printed inside the arm.

AT THE BRIDGE

Steady, without sliding

The frame rests evenly and does not creep down.

AT THE TEMPLES

Close to parallel

The arms do not flare out or press into the sides.

AT THE CHEEKS

Clear when you smile

The lower rim should not lift with your cheeks.

AT THE EYES

Comfortably centred

Your eyes sit naturally within the lens opening.

IN THE BALANCE

No pinch or tilt

The frame feels even, without one-sided lift.

MORE ROOM, OR LESS?

Find a useful starting point.

Chosen by our team, not by a face-shape rule.

These references help you begin. Final fit still depends on the bridge, eye position and how the frame sits on you.

ONE DESIGN, ANOTHER SIZE Evans, with more room when you need it.

STANDARD 47–21 A more compact front.

Same design language, with a larger eye size. The bridge remains 21 mm, so the relationship at the nose still matters.

SHORT ANSWERS

A few things people ask us.

What do the numbers on my glasses mean?

Lens width, bridge width and temple length. Read them together with overall frame width.

Why can two frames with the same size fit differently?

Bridge shape, rim depth, material and overall width all change the result.

How do I know if my glasses are too narrow or too wide?

Look for temple pressure or flare, cheek contact, sliding, or too much space at the sides.

Can nose pads be added to acetate glasses?

Sometimes. Suitable frames can be assessed in store for custom titanium-arm nose pads.

Can I walk in and try frames without an appointment?

Yes. Pop by any O+ store, no appointment needed.

The best-fitting frame is the one you stop noticing.

Read the measurements online, or pop by with the pair you already wear.
