Combination frames join two materials in one pair, most often a metal front with acetate temples, or an acetate front with metal details such as a brow bar, bridge or arms. You get the slim lines of metal where they help and the warmth and grip of acetate where they matter. They suit people who find all-metal frames a little cold and all-acetate frames a little heavy.
What counts as a combination frame?
Any frame that deliberately mixes materials in its visible structure. Opticians sometimes call them "combi" or mixed-material frames. The mix is never random: each material is placed where its strengths show.
- Metal front, acetate temples. A thin steel or alloy rim around the lenses, with thicker acetate arms. Clean from the front, softer at the sides.
- Acetate front, metal temples. A bold acetate rim with slim metal arms, often finished with acetate tips behind the ears.
- Acetate rims, metal brow or bridge. The lens rims are acetate, joined by a metal bar or bridge across the top. Browline and double-bridge styles sit here.
- Rimless with acetate arms. No rim at all, just a metal bridge holding the lenses and acetate temples carrying the colour.
Why designers mix acetate and metal
Each material does some jobs well and others less well. Combining them is a way of keeping the best of both.
| Part of the frame | In metal | In acetate |
|---|---|---|
| Front / rim | Thin, light, keeps the eye area open | Bold outline, rich colour and patterns |
| Bridge | Often with adjustable nose pads | Moulded saddle, no pads to clean |
| Temples | Slim, discreet from the side | Warmer to the touch, a little more grip |
| Overall look | Minimal, technical | Expressive, retro or fashion-led |
Put together, a metal front with acetate arms reads as light and precise when someone faces you, then shows a flash of colour from the side. An acetate front with a metal brow gives a strong outline without the full weight of a thick rim all the way round.
Four combinations and who they suit
Steel front, acetate temples
A good bridge between a business look and a weekend one. Our Dubuque sunglasses pair a slim stainless steel front with hand-finished acetate temples on a medium-fit square shape. It works well if you like a tailored, understated frame but want the arms to feel substantial. The Tiamo aviator takes the same idea in a softer pilot shape: a gold metal front with black acetate temples for contrast at the sides.
Rimless with acetate arms
The most minimal version. Bonterey-FC09 has no rim, a polished gold metal bridge and tortoiseshell acetate temples, with 53 mm lenses and a 136 mm frame width. From the front the glasses almost disappear; the tortoise arms add warmth by the hairline. A good pick if you want your features, not the frame, to lead.
Acetate front, metal arms
The Alva sunglasses combine a hand-polished acetate front with two-tone metal arms and a keyhole bridge, on a deeper lens shape designed for smaller faces. You keep the colour and depth of acetate at the front while the slim arms keep the side profile light.
Acetate rims with metal details
Round and cat-eye styles often use metal as an accent rather than a structure. Monterey joins nickel-free metal with acetate rims and acetate temples for a retro round look. Eureka is a larger cat-eye in acetate mixed with metal, with double rivets at the corners and temples.
How to choose your mix
- Decide which view matters more. If people mostly see you face on (desk work, video calls), the front material sets the tone. If you wear your hair back or have short hair, the temples are on show too.
- Match the dominant material to your features. Strong brows and bold features carry an acetate front well. Finer features often look balanced with a metal front and colour kept to the arms.
- Pick one metal tone and one acetate colour that agree. Gold with tortoise or brown feels warm; silver or gunmetal with black or grey feels cool. Mixing warm and cool can work, but keep it deliberate.
- Check the size first. A combination frame is still a frame: lens width, bridge and total width decide comfort. Our frame size guide shows how to compare with a pair you already own, and the face shape guide helps with the outline.
Fit and care for mixed materials
Because two materials meet, combination frames have a few small details worth knowing:
- Joints and hinges. The point where metal meets acetate is usually a hinge or a rivet. Fold the arms gently and avoid opening the glasses with one hand.
- Cleaning. Lukewarm water, a drop of mild soap and a microfibre cloth suit both materials. Avoid alcohol-based cleaners on acetate, as they can dull the polish.
- Heat. Acetate softens with heat, metal does not. Do not leave the glasses on a car dashboard or near a heater, where the acetate part can lose its shape before the metal does.
- Adjustment. Acetate temples are warmed to adjust; metal parts are bent cold. If the fit needs changing, let a local optician handle it so neither material is stressed.
Frequently asked questions
Are combination frames heavier than metal frames?
Usually a little heavier than an all-metal frame of the same size, and often lighter than a full acetate frame with a thick rim. Rimless styles with acetate arms are among the lightest options.
Can combination frames take prescription lenses?
Yes. You can add prescription lenses in our lens selector, including prescription sun lenses for many of our sunglasses. Rimless frames work best with moderate prescriptions because the lens edge is visible.
Are combination frames a good choice for sensitive skin?
Many people find them comfortable because the parts that touch the skin behind the ears are often acetate. Check each product page for the specific metal used; Monterey, for example, uses nickel-free metal.
Do combination frames suit both men and women?
Yes. Square steel-and-acetate shapes lean classic and are popular with men, while round, cat-eye and rimless versions are often chosen by women, but none of these rules are fixed.
