Market evolution: Plastic spectacle lenses (CN 900150) — 2015–2025

Introduction

This report examines the EU's external trade in spectacle lenses made of materials other than glass (customs code 900150) over the period 2015–2025. The product covers plastic and polymer-based unmounted lenses, including partly finished blanks, fully finished lenses, and both vision-correction and non-vision-correction variants. The analysis draws on trade flows between the EU and non-EU countries, EU domestic production data, partner concentration indicators, and product-level breakdowns. Three major dynamics emerge from the decade under review: a decisive shift toward higher unit values at the expense of physical volumes, a growing structural dependence on Asian suppliers that has doubled the EU's net import reliance, and an uneven redistribution of trade activity across EU member states.

1. Trading More Value on Less Volume: The EU's Upmarket Pivot

1.1 Export prices surged while physical shipments shrank

EU exports of plastic spectacle lenses illustrate a clear upmarket trajectory. Between 2015 and 2025, the total value of exports rose modestly from €394.5 million to €417.9 million (+5.9%), yet the corresponding weight fell sharply from 2,782 tonnes to 1,972 tonnes (−29.1%). The number of pieces exported followed a similar downward path, declining from 62.3 million to 46.0 million units (−26.1%). The only explanation for a rising total value on shrinking volumes is a steep climb in unit prices: the average export price per tonne increased from €141,411 to €211,137 (+49.3%), and the per-piece price rose from €6.34 to €9.09 (+43.4%).

This pattern is consistent with the EU specializing in higher-value-added lens segments—complex finished products, advanced coatings, and premium optical solutions—while offloading commodity-grade production to lower-cost locations.

1.2 Import volumes grew modestly but import values surged even faster

Imports tell a complementary story. Total import value climbed from €857.0 million in 2015 to €1,216.2 million in 2025 (+41.9%), while import weight grew only from 8,272 tonnes to 9,066 tonnes (+9.6%) and piece counts from 275.0 million to 296.3 million (+7.7%). Import prices per tonne rose from €103,589 to €134,134 (+29.5%), and per-piece prices from €3.12 to €4.10 (+31.7%). The gap between the 41.9% increase in import value and the modest 7.7% increase in import piece-count points to a combination of genuine price inflation (driven by material and labor costs in origin countries) and a compositional shift toward higher-specification lenses.

1.3 The product mix confirms a move up the value chain

A granular look at the four product sub-headings reinforces the upmarket narrative. The largest import segment by weight—partly finished lenses (90015080)—remained broadly stable in tonnage (around 5,000 tonnes), while finished lenses for vision correction (90015049) saw their per-tonne price almost double from €209,049 in 2015 to €442,656 in 2025. On the export side, the same sub-heading (90015049) recorded a per-tonne price increase from €386,105 to €833,762—more than doubling over the decade. These shifts indicate that the EU's export basket has moved decisively into higher-margin finished optical products, while imports increasingly supply both the mid-range and the higher-end of the European market.

2. Asia Consolidates Its Grip: Supplier Concentration and the Widening Deficit

2.1 Thailand and China dominate imports, with Vietnam emerging rapidly

The geography of EU imports shifted markedly toward Asia. In 2015, Thailand was already the leading supplier at €330.1 million, followed by China at €157.9 million and India at €76.3 million. By 2025, Thailand's shipments had grown to €537.3 million (+62.8%), China's to €283.8 million (+79.7%), and India's to €111.7 million (+46.5%). The most dramatic growth, however, came from Vietnam, which expanded from just €16.8 million to €54.4 million (+223.9%) and from Mexico, which grew from €12.0 million to €31.7 million (+165.0%). The United States, by contrast, saw its position erode from €30.0 million to €11.3 million (−62.3%). View top trade partners

2.2 Import concentration has tightened, exposing the EU to supply-chain risk

The Herfindahl–Hirschman Index (HHI) for import concentration by value rose from 2,066 to 2,688 (+30.1%) over the decade, indicating that imports have become more concentrated among fewer dominant suppliers. In a sector where optical-grade polymers, precision molding, and coating technologies are capital-intensive, the consolidation of production in a handful of Asian countries creates potential vulnerability. The volatility data underlines this risk: while Thailand and China are relatively stable suppliers (coefficients of variation of 0.14 and 0.13 respectively), Vietnam shows considerably higher volatility (CV 0.43), meaning its rapid growth has come with less predictable year-on-year shipments.

2.3 The trade deficit has widened as domestic production declines

The EU's net trade deficit in plastic spectacle lenses deteriorated from €462.5 million in 2015 to €798.4 million in 2025 (−72.6%). Net import reliance—measured as net imports divided by apparent consumption—more than doubled from 10.5% to 23.6%. Over the same period, EU domestic production fell from 253.8 million pieces to 183.0 million pieces (−27.9%), even as production value rose from €2.12 billion to €2.72 billion (+27.9%). This divergence—fewer units at higher values—is consistent with the same upmarket shift observed in trade data: EU manufacturers are concentrating on premium products while relinquishing volume segments to imports.

2.4 Export concentration has diversified, driven by Switzerland's rise

While import sources have consolidated, the EU's export destinations have become more diversified. The export HHI dropped from 1,937 to 1,327 (−31.5%). The most striking shift has been the surge of Switzerland as an export market, growing from €40.4 million to €100.9 million (+149.4%), making it the EU's single largest export destination by value in 2025. Meanwhile, the United Kingdom—historically the top export market at €156.7 million in 2015—fell to €94.0 million (−40.0%), a decline likely linked to post-Brexit trade friction. China also became a more significant export destination, rising from €6.7 million to €22.2 million (+232.8%). View top trade partners

3. An Uneven European Landscape: Shifting Roles Among EU Member States

3.1 France and Germany dominate imports, while Poland's role has exploded

The distribution of import activity across EU member states has evolved significantly. France remained the largest EU importer, growing from €254.0 million to €435.1 million (+71.3%). Germany followed with growth from €216.1 million to €303.4 million (+40.4%). The most dramatic change, however, occurred in Poland, which grew from a mere €7.5 million to €75.0 million—an extraordinary increase of 905.4%. Hungary also saw substantial growth, rising from €43.9 million to €77.8 million (+77.5%). These shifts likely reflect the expansion of optical manufacturing and assembly activities in Central and Eastern Europe, where lenses imported from Asia are further processed, coated, or assembled into finished eyewear.

3.2 Export leadership has shifted from France to Germany and Italy

On the export side, Germany consolidated its position as the EU's leading exporter, growing from €92.1 million to €141.8 million (+53.9%). Italy more than tripled its exports from €15.3 million to €47.7 million (+212.6%), reflecting the country's well-established eyewear manufacturing cluster. France, by contrast, saw a sharp contraction from €78.9 million to €32.1 million (−59.4%), losing its former prominence. Hungary also declined from €58.0 million to €36.3 million (−37.4%), suggesting a shift from exporting finished products to importing blanks for further processing. View EU member state exports

3.3 Production specialization is concentrated in a handful of member states

The 2025 specialization data reveals that only a small number of EU countries have meaningful comparative advantage in spectacle lens production. Portugal leads with an RSCA of 0.606, followed by Hungary (0.484), Czechia (0.449), France (0.237), and Poland (0.205). At the other end, Bulgaria, Slovakia, Luxembourg, Malta, and Croatia have negligible production shares. This geographic concentration of specialization implies that the EU's production base for plastic spectacle lenses is fragile—dependent on a small number of countries that could be affected by localized disruptions.

Conclusion

The EU's trade in plastic spectacle lenses over 2015–2025 has been defined by a structural transformation. The bloc has moved decisively toward higher-value products—both in what it exports and in what it imports—while ceding volume production to Asia. This upmarket shift has kept export revenues broadly stable despite a nearly 30% decline in physical shipments, but it has also deepened the EU's import dependence. The trade deficit widened by 73% to nearly €800 million, and net import reliance more than doubled to 23.6%.

Thailand, China, and increasingly Vietnam have consolidated their positions as the EU's primary suppliers, raising concerns about supply-chain concentration. Meanwhile, the UK's decline as an export destination—partially offset by the surge of Switzerland—reflects the realignment of European trade flows in the post-Brexit environment. Within the EU itself, the production and trade landscape has been reshaped: Germany and Italy have strengthened their export positions, while France has retreated; Poland has emerged as a major importer, likely reflecting the growth of Central European optical processing hubs.

Looking ahead, the EU faces a delicate balancing act: maintaining its competitive edge in high-value optical products while managing growing reliance on a concentrated set of Asian suppliers. Policies aimed at strengthening domestic production capacity, diversifying import sources, and investing in next-generation lens technologies will be critical to ensuring the resilience of this strategically important sector.
