Here is what causes them, how to tell whether your frame can take adjustable pads, how to size replacements, and the fixes for a frame with a moulded bridge.

Fit · October 16, 2026 · 6 min Sunglasses for a square face: why curves work, and the frame that fights your jaw A square face has a broad forehead, a strong jaw and a similar width top to bottom. Rounded and oval frames soften that angle; another square frame competes with it. Here is what to look for and the width rule that outranks shape.

Fit · October 16, 2026 · 7 min Sunglasses for a small face: the measurements that matter and why most frames are too big Most sunglasses are built for average adult heads, which leaves smaller faces with frames that slide, sit low and cover too much. Here are the numbers to shop by, the adjustments that help, and why youth frames are a genuine option.

Fit · October 16, 2026 · 7 min Sunglasses for a round face: the shapes that work, and the one that never does A round face is widest at the cheeks with a soft jaw and little angle. Angular frames with a strong top line add the structure the face does not have. Here is what to look for, what to avoid, and why width matters more than shape.

Fit · October 16, 2026 · 7 min Sunglasses for a large head: the width you need, and why most frames give up at 145mm If frames pinch your temples, leave marks behind your ears or snap at the hinge, the problem is width, not style. Here are the measurements that define a wide fit, what to search for, and the adjustments that buy a few extra millimetres.

Fit · October 16, 2026 · 6 min How to measure your face for sunglasses, and which number actually decides the fit Three measurements — face width, bridge and temple-to-temple — tell you which frames will fit before you try a single pair. Here is how to take them with a tape and a mirror, and how to compare them against the numbers printed on the arm.

Fit · October 16, 2026 · 7 min How should sunglasses fit? The six-point check an optician does in thirty seconds Sunglasses that fit properly sit level, touch your head in three places, clear your brow and cheeks, and do not move when you look down. Here is the check an optician runs, in order, and what to do when a pair fails each one.

Fit · September 30, 2026 · 4 min Why do my sunglasses give me a headache? Six causes, in order of likelihood A headache from sunglasses is almost always the frame, not the lens: too tight at the temples, too heavy on the nose, or pressing behind the ears. Less often it is the lens: distortion, a tint too dark for the light, or an unaccustomed polarized view. Here is how to tell which, and what to do about each.

Fit · September 30, 2026 · 4 min Sunglasses measurements explained: what 60-15-145 means and which number decides fit The three numbers on a sunglasses arm are lens width, bridge width and temple length, in millimetres. The number that actually decides whether a pair fits, the frame width, is usually not printed. Here is how to read all four and measure your own face.

Fit · September 30, 2026 · 4 min Sunglasses keep slipping down your nose? The three causes and the fix for each Sunglasses slip for three reasons: the frame is too wide for your face, the temple arms do not grip behind the ears, or the bridge is the wrong shape for your nose. Each has a different fix, from a frame that fits to a one-dollar pair of silicone nose pads. Here is how to tell which is yours.

Fit · September 30, 2026 · 4 min Sunglasses for your face shape: the one rule that works, and the ones that do not Face-shape guides all say the same thing in six variations: pick a frame that contrasts your face's dominant line. That rule works. What matters more, and what the guides skip, is width. A frame that is the wrong width looks wrong on every face shape. Here is the rule, the six shapes, and how to measure.

Fit · September 30, 2026 · 4 min Low nose bridge sunglasses: why standard frames slide, and what "Asian fit" actually changes Most sunglasses are designed around a nose bridge that sits high between the eyes. If yours sits lower, or your cheekbones sit higher, a standard frame perches on the tip of the nose, rests on the cheeks, and slides. Low-bridge frames change three measurements to fix it. Here is what they are, how to tell if you need one, and what to do with a frame that is close.
