Your plastic frames cost 5 euros to make. The rest is margin and a logo. Here’s how a single conglomerate locked down the entire chain.

I’ve worn glasses since the age of seven. I’ve bought dozens of pairs. Thin ones, thick ones, round, rectangular, expensive and not-exactly-cheap. And for a very long time, I never asked the question that should have been staring me in the face.

Why do all frames cost between 300 and 500 euros?

Not some of them. Not the most luxurious ones. All of them. Whether at a neighborhood optician or a mall chain, whether the brand is Italian, American, French, or Japanese, prices converge on the same range. As if it were the natural price of a pair of glasses. As if it couldn’t cost less.

It can. And once you understand why it doesn’t cost less, you’ll never look at an optician’s window the same way again.

The price of a frame

Let’s start with the facts. A cellulose acetate frame - the material used for virtually all “designer” glasses - costs between 4 and 15 euros to manufacture. In a modern factory, with CNC machines cutting and polishing the parts, hundreds are produced per day. The material cost is negligible. Acetate is a plastic, derived from wood pulp - granted, nobler than nylon or cheap injection molding, but a plastic nonetheless.

Add the hinges (a few cents per unit in mass production), the packaging, the logistics. For a frame retailing at 399 euros, the all-in production cost lands between 15 and 30 euros.

Where does the difference go? That’s where the story gets interesting.

The machine

To understand, you have to go back to an optician in Lombardy who, in the 1960s, began buying up everything remotely connected to eyewear. Manufacturers, distributors, brands, optical chains. Methodically. Over decades.

The result is a conglomerate controlling a colossal share of the global optical chain. Manufacturing? Dozens of factories. Distribution? Thousands of retail locations under different banners, all owned by the same group. Licenses? Dozens of fashion houses entrust the manufacturing of their eyewear to the same player. When a customer walks into one of its stores and chooses between an Italian brand frame, a French brand frame, and an American brand frame, they’re really choosing between three products from the same factory, sold by the same group, with margins set by the same board of directors.

And it doesn’t stop there. In the United States, the same group also controls optical insurance. The insurer reimbursing the glasses belongs to the manufacturer selling them. The loop is closed.

When you own manufacturing, distribution, and insurance, you set whatever price you want. And you set it high.

The logo trick

The mechanism is simple. A fashion house signs a licensing agreement. The conglomerate manufactures the glasses, distributes them, handles the marketing. The brand collects a percentage. The acetate frame that costs 15 euros to produce gets stamped with a logo and sold for 400 euros.

The customer thinks they’re buying fashion, design, a name. They’re buying a margin.

The masterstroke is that nobody knows. Or rather, nobody wants to know. Opticians aren’t going to tell their customers that the 450-euro frame and the 250-euro frame sometimes come off the same production line. Fashion brands aren’t going to admit that their eyewear is a licensed product manufactured without their oversight. And the conglomerate has no interest in making any of this visible.

Everyone is complicit. The customer pays.

The Oakley turning point

The most revealing episode dates back to 1996. An American sports eyewear manufacturer, based in California, refused to bend. Its founder publicly denounced the system, described the margins, named the mechanisms. The conglomerate pulled his products from its stores. The rebel manufacturer’s stock dropped 33%.

Eleven years later, in 2007, the conglomerate bought it for 2.1 billion dollars. Then merged with another French optical giant to form a publicly traded behemoth worth tens of billions of euros.

The opposition became a subsidiary. The dissent was absorbed. Literally.

What the price hides

399.99 euros for a plastic frame is a price that bears no relation to the reality of the product. It’s a price that reflects a monopoly, vertical control of the chain, and the fact that nobody - not the optician, not the insurer, not the brand - has any incentive for things to change.

The customer pays a brand license (30% of the price on average for fashion licenses), a distributor margin (the optician or chain), a manufacturer margin, marketing, and somewhere in the middle of all that, a few euros of material and labor.

It’s not illegal. It’s even commonplace - luxury often works this way. But in luxury, you know you’re paying for the name. With glasses, you believe you’re paying for a health need. You believe it’s expensive because it’s technical. You believe the optician has reasonable margins. None of that is true.

Those who do it differently

Against this system, a handful of independent eyewear makers prove you can craft exceptional glasses without belonging to the machine. They’re few in number. And they’re not pretending.

Masunaga - a century of Japanese eyewear

Masunaga has manufactured in Sabae, Fukui Prefecture, since 1905. Sabae is the Northampton of eyewear: 95% of Japanese frame production is concentrated there. Masunaga owns its own factory, which has become rare even in Sabae, where subcontracting now dominates.

Each frame goes through over 200 steps. Titanium is cut, bent, welded, hand-polished. Acetate is milled from solid blocks, not injection-molded. Hinges are riveted, not glued. It’s slow, meticulous, and it shows.

Anyone who’s held a Masunaga talks about the same thing: the weight, or rather the absence of weight. The precision of the fit. The feeling that every piece is exactly where it belongs. The finishing is universally praised by eyewear enthusiasts. The only debates are about the design, sometimes considered too conservative, and the prices, which remain high for the category (expect 400 to 600 euros). But here, the price reflects the manufacturing. Not the license.

Jacques Marie Mage - the Californian artisan

Founded in Los Angeles in 2014 by Jérôme Mage, the brand established itself in just a few years as a benchmark in independent eyewear. Each collection is limited, often to a few hundred pieces. The design draws from vintage America: shapes inspired by the 1940s through 1970s, bold, angular, full of character.

Manufacturing is Japanese, in Sabae. Materials are carefully selected: Italian acetates from Mazzucchelli, Japanese titanium, wood or horn inlays on certain editions. These are glasses as jewelry.

Opinions are polarized, and that’s almost a compliment. Fans praise the exclusivity and material quality. Others find the designs too loud, the prices too steep (500 to 900 euros), and the artificial scarcity irritating. But nobody disputes the craftsmanship.

Garrett Leight - the Californian classic

The son of Larry Leight, founder of Oliver Peoples (before the brand was acquired by the conglomerate), launched his own house in 2011. Garrett Leight California Optical operates in a different register: classic, clean shapes in the American optical tradition. Less dramatic than Jacques Marie Mage, more wearable day to day.

Manufacturing is primarily Japanese, with some models assembled in Italy. Prices are more accessible: 250 to 400 euros. Reviews are generally positive on comfort and durability. The hinges hold, the acetates age well. The main criticism is a design sometimes deemed too understated - but that’s precisely what Garrett Leight buyers are looking for.

Lunor - German rigor

Based in the Black Forest, Lunor is the European answer to mass-market eyewear. Founded in 1991, the brand specializes in small classic frames, often round or oval, in metal or acetate. The design is austere to the point of asceticism.

Manufacturing combines traditional craft and small-batch production. Metal frames are riveted the old-fashioned way. The attention to proportion is obsessive - each model comes in multiple sizes for a precise fit, something virtually no other brand offers. Eyewear aficionados appreciate this rigor. Prices are restrained for this level of finishing: 250 to 450 euros.

Matsuda - the sculptor

Founded in Tokyo in 1967 by Mitsuhiro Matsuda, the brand has become a cult name for its architectural frames. Designs draw from steampunk, gothic, art deco, with a boldness few eyewear makers dare attempt. Matsuda is eyewear as a work of art.

Japanese manufacturing, premium materials (titanium, gold, high-grade acetate). Prices are steep - often above 500 euros - but the construction matches. Connoisseurs praise the complexity and originality of the designs. The recurring complaint: availability. Matsuda is hard to find, the opticians who carry them are few, and certain pieces resell above retail.

Ahlem - Parisian elegance

Ahlem Manai-Platt created her brand in Los Angeles in 2014. Born in Paris, she designs frames that breathe the Paris of the 1950s: soft lines, powdery colors, delicate proportions. Each model is named after a Parisian neighborhood or street.

Manufacturing takes place in France and Japan. The acetates are hand-cut. The brand stays small, deliberately. Reviews are warm: people praise the elegance, the lightness, the fact that the frames suit fine-featured faces particularly well. The main regret among enthusiasts: the distribution network remains limited, and trying them on in a store is difficult outside Paris or Los Angeles.

The real price of glasses

What these independent eyewear makers demonstrate is that a frame crafted with care, in small batches, with quality materials, costs between 250 and 600 euros. That’s expensive, but it’s the real price of artisanal work.

The scandal isn’t that a Masunaga costs 500 euros. The scandal is that a mass-produced licensed frame costs the same - or more - for an incomparably inferior product. The customer pays the same amount, but in one case they’re buying craftsmanship, and in the other they’re buying marketing.

The difference is visible. You can feel it. An artisanal frame lasts ten years. The hinges don’t give out after eighteen months. The acetate doesn’t turn white. The metal doesn’t warp at the first bump.

And above all, you know what you’re buying. You know the factory, the town, the people. There’s no license, no opaque middleman, no conglomerate between the product and the person wearing it.

How to navigate this

Next time you push open an optician’s door, ask three questions.

Who makes this frame? If the optician doesn’t know - or won’t say - that’s a bad sign.

Where does it come from? “Made in Italy” isn’t enough. It could mean assembled in Italy from Chinese parts, or manufactured in one of the conglomerate’s factories in Agordo.

Why this price? An honest optician will break down the share of the margin, the license, the reimbursement. A dishonest one will change the subject.

And if you want to go further: seek out the independents. Masunaga, Garrett Leight, Lunor, Matsuda, Jacques Marie Mage, Ahlem. They’re not in every window. You may need to order online, or travel. But at least when you pay 400 euros, you know the money is going to someone who actually makes something.

Not to a conglomerate that locked the system so you’d have no choice.
