What "metal frame" actually means
Four metals cover almost every metal frame on sale, and the word on the listing rarely says which.
- Stainless steel. The workhorse: strong, corrosion resistant, inexpensive and a little heavier than the others. Most thin "metal" frames at the lower end are steel.
- Titanium. Lighter than steel, more corrosion resistant, and the usual choice for thin, minimal frames that still hold their shape. Pure titanium is stiff; the titanium glasses guide covers the grades.
- Beta titanium. A titanium alloy that flexes and springs back. It is the metal that matters for temples, because a beta titanium arm can be bent a long way without staying bent.
- Nickel alloys and aluminium. Monel and similar alloys are cheap, easy to plate and easy to adjust, and they are the metals most often behind a skin reaction to a frame. Aluminium is light and takes colour well but does not flex, so it is rare on anything that has to bend.
The metal is usually plated or coated, which is why a gold frame is not gold and a black metal frame is not black all the way through. The coating is what wears first.
Are metal frames better than plastic?
Better at some things, worse at others, and the honest answer depends on what you want the frame to do.
Where metal wins:
- Weight. A thin metal frame is lighter than almost any acetate frame of the same size, and the weight is the first thing you notice after a week.
- Profile. The rim is thin, so the frame shows less face and reads as a line rather than a shape. If you want glasses that disappear, metal is the route.
- Adjustability. Nearly every metal frame carries nose pads on arms, which can be set to your nose, and metal temples can be shaped by an optician in a minute. Acetate can be adjusted too, but less, and with heat.
- Durability of the shape. A good metal frame does not go slack at the hinge the way a plastic one can.
Where acetate wins:
- Colour and depth. Acetate carries tortoise, crystal and layered colour in a way plating cannot, and a thick acetate rim is a statement a metal rim is not. The acetate glasses guide covers the material.
- Skin. Some people react to nickel, and nickel alloys sit under a lot of inexpensive plating. Titanium and stainless steel are the safe metals; if a frame has ever left a mark or an itch at the temples, that is the first thing to check.
- Cold and heat. Metal is cold on the face on a winter morning and hot in the sun; acetate is neither.
- Bending. A metal frame bends. Beta titanium springs back; steel and alloys do not, and a sat on steel frame stays bent until an optician straightens it.
So: metal frames are better for weight, thinness and fit adjustment; plastic frames are better for colour, presence and anyone who reacts to nickel.
Are metal frame glasses still in style?
Yes, and more than two years ago. Three things are driving it. The thin wire round and oval frames of the 90s have come back on younger faces, and those are metal by definition. The combination frame, an acetate front on metal temples, has become the standard construction for anyone who wants colour at the front and lightness at the sides. And the rimless and half rimless frames that were an office joke for a decade now read as minimal rather than dated, because the acetate rim was the dominant look for long enough that its absence looks fresh. The glasses trends 2026 guide covers the whole picture; the short version is that thin metal in gold, silver and gunmetal is the frame of the moment, and the chunky acetate square is the one that reads as last decade.
Who metal frame glasses suit
The rule for any frame is contrast, and metal frames add the least, so they suit faces and features that do not need the frame to do much.
- Fine or small features. A thin metal frame does not swamp them, where a thick acetate one would.
- Anyone who wants the frame to disappear. For work, for a face that is already strong, or simply because you would rather be seen than your glasses.
- Mature faces. A thin metal frame adds no weight to a face and reads as considered; a heavy rim can read as a costume.
- Round and oval shapes. A thin metal round or oval is the vintage version of both, and the most forgiving.
Strong features and a strong jaw often prefer acetate, because a thin frame can look lost on them. A large face wants a larger metal frame, not a thicker one; the width rule applies to metal exactly as it does to acetate. The thin frame glasses guide covers when thin is too thin.
Metal frames on a lower nose bridge
This is where metal earns its keep. Most frames that slide down the nose slide because the bridge was built for a higher nose than the one wearing them, and an acetate frame with a solid saddle bridge can only be fixed so far. A metal frame with nose pads on arms can be set to sit higher, closer or further apart, and the nose pads for glasses guide explains how. The adjustable nose pad glasses collection gathers the frames that have them. A frame cut for a lower bridge goes further still: the bridge is placed lower, the lens tilt is reduced and the front is shaped to clear the cheeks. Many of our frames are cut this way, in metal and in acetate, and the low bridge fit eyeglasses collection lists them.
Looking after a metal frame
Three habits keep a metal frame straight. Take it off with both hands, so one temple is not levered out every day. Check the screws at the hinge every few months and tighten them before they fall out, not after. And rinse salt off it, sweat in summer and sea air on holiday, because salt is what gets under plating and starts the wear. If the temples have opened out or the frame sits crooked, the guide to adjusting glasses arms covers what you can do at home and when to let an optician do it.
MUJOSH metal frames
The optical side of the MUJOSH US range is mostly acetate, Ultem and other light plastics, and the one frame with metal in it is a combination: Beta Pitot, $135, a square round with a glossy acetate front on laser matte beta titanium temples, low bridge fit, two colourways. The acetate carries the colour and the titanium carries the flex, which is the argument of this whole article in one frame. It sits in the titanium glasses collection and the eyeglasses collection.
The metal choice is widest in sunglasses, and the metal frame glasses collection holds them:
- Maga KC, $79: a square in metal with flat flush mounted polarized lenses, nose pads and a low bridge fit, two colourways.
- Screwless Polarized, $99: an oversized square in screwless metal, polarized, low bridge fit.
- Pearl-Accented, $99: a rimless diamond cut lens on titanium temples with a small pearl detail, polarized, adjustable nose pads. The lightest frame in the range.
- Aviator Total, $99: a metal aviator with adjustable nose pads and a low bridge fit, four colourways.
- Lady Lang, $119: a screwless cat eye in metal with a clean hinge free front, polarized, adjustable nose pads, low bridge fit.
The bottom line
Metal frame glasses are lighter, thinner and easier to adjust than plastic ones, and they carry less colour, run cold in winter and can mark skin that reacts to nickel. Choose titanium or stainless steel over a plated alloy, choose beta titanium temples if the frame has to survive being sat on, and let the nose pads do the fitting. They suit fine features, mature faces and anyone who wants the frame to disappear, and they are back in style in the thin round, oval and rectangular shapes. In the MUJOSH range, Beta Pitot is the optical combination frame and Maga KC, Screwless Polarized, Pearl-Accented, Aviator Total and Lady Lang are the metal sunglasses.
Silver is the cool-toned metal; the silver sunglasses guide covers who it suits and the pairs that carry it.
The sunglasses half of the material, with the three metal frame types and nine pairs, is in the metal frame sunglasses guide.
Frequently asked questions
Are metal frames better than plastic frames for glasses?
Better for weight, a thin profile and fit adjustment, because nearly all metal frames carry nose pads and the temples can be shaped. Plastic frames win on colour, presence and for anyone whose skin reacts to nickel. Titanium and stainless steel are the metals to choose.
Are metal frame glasses in style?
Yes. Thin metal round, oval and rectangular frames in gold, silver and gunmetal are the frame of the moment, along with combination frames that put an acetate front on metal temples. The chunky acetate square is the shape that reads as last decade.
Which metal is best for glasses frames?
Titanium for a thin frame that stays light and resists corrosion, beta titanium for temples that flex and spring back, stainless steel as the strong and inexpensive option. Plated nickel alloys are the cheapest and the most likely to mark the skin.
Which MUJOSH glasses have metal frames?
Beta Pitot is the optical frame, an acetate front on beta titanium temples. In sunglasses, Maga KC, Screwless Polarized, Pearl-Accented, Aviator Total and Lady Lang are metal, and the metal frame glasses collection lists them.
Are stainless steel glasses frames good?
Stainless steel is one of the standard frame metals: it is light, it resists corrosion from sweat and skin, it takes plating in gold, silver and gunmetal, and it holds an adjustment well. It is heavier and a little stiffer than titanium and lighter than the older nickel alloys. The product page names the metal on each frame; in the MUJOSH optical range the metal is in the temples of Beta Pitot, which are beta-titanium, and the titanium glasses guide covers how that compares.
