Best Glasses for a Diamond Face (Women & Men)
A diamond face has prominent, wide cheekbones framed by a narrower forehead above and a narrow chin below. Eyewear that places visual emphasis along the upper rim broadens the brow line so your temples balance your standout cheekbones. The rule: Choose top-accented or softly curved frames - browline, cat-eye, oval, or horn-rimmed - no wider than your cheekbones to broaden the forehead.
Frame styles that flatter a Diamond face
Where a heart face avoids top-heavy frames, a diamond face thrives on them because the upper third is naturally narrow:
Browline / Clubmaster
A defined upper bar draws a broader horizontal line across the narrow forehead while the thin lower rim leaves cheekbones uncluttered.
Cat-Eye frames
Upswept upper corners expand apparent temple width and harmonize with high cheekbones.
Oval & Soft Round frames
Curved rims soften the angular diamond taper at the forehead and chin.
Semi-rimless top-bar frames
Concentrates visual weight at the brow line where a diamond face benefits from extra breadth.
Frames to avoid & fit checklist
Avoid narrow, boxy rectangular frames and frames wider than your cheekbones, which make the cheekbones jut out and the temples look pinched.

Glasses for a Round Face
Choose angular frames - rectangular, square, wayfarer, browline, or cat-eye - slightly wider than your cheekbones to contrast soft curves.
Glasses for a Square Face
Choose curved frames - round, oval, P3, aviator, or soft cat-eye - that sit high on the nose bridge to soften angular jaw corners.
Glasses for a Oval Face
Choose frames as wide as the widest part of your cheekbones - structured walnut, wayfarer, rectangular, or geometric shapes add crisp definition.
Glasses for a Heart Face
Choose frames with light or thin upper rims and rounded or wider lower bowls - round, aviator, oval, or rimless - to balance a broader forehead.
Glasses for a Oblong Face
Choose deeper lenses with strong horizontal lines - tall wayfarers, oversized squares, aviators, or thick acetate - to shorten vertical length.
Glasses for a Triangle Face
Choose top-heavy frames - browline, cat-eye, D-frame, or bold upper-rim aviators - slightly wider at the top to balance a wide jawline.
