Eclipse fever leaves Europe scrambling for certified glasses

Across much of Europe, the approach of a solar eclipse has triggered a rush for certified viewing glasses, leaving many citizens unable to obtain the protective eyewear needed to watch the event safely.

Supply chain under pressure

In Spain, the National Museum of Natural Sciences in Madrid announced that its allocation of free glasses, part of a government‑run distribution of two million pairs, has been exhausted. While a few central Madrid pharmacies still sell certified glasses for €3‑4 a pair, many retailers are out of stock. Optical shop owner Carles Sisquella in Barcelona told reporters his store has been empty for ten days, and a shopper named Mabel said she "has been asking around since Friday, but they're nowhere to be found."

Similar shortages are evident in Belgium, where about 90 percent of the Sun will be obscured. Optician manager Fouad Mehdaoui explained that a last‑minute shipment of 100 pairs vanished within half an hour of arrival.

Two boxes just came in with 100 pairs in total -- they were gone in 30 minutes,

In France, pharmacies in Paris have been cleared of stock, with customers queuing for €5.95 pairs only to find empty boxes. The pharmacist warned that a new shipment of 500 pairs is expected later in the day, describing the situation as "pure madness." President of the Federation of Pharmaceutical Trade Unions, Philippe Besset, said demand far exceeded the 200‑pair allocations offered to pharmacies a few months ago.

Health warnings and market response

Doctors stress that looking directly at the Sun without proper protection can cause irreversible retinal damage, potentially destroying the cells responsible for sharp central vision. In response, Spanish regulators have withdrawn six non‑certified models from the market to curb the risk of eye injuries.

In Portugal, the Club da Visão network of over 600 opticians initially offered free certified glasses, limited to one per person, but repeated restocks have also run dry.

What comes next?

Authorities across the affected countries are likely to increase monitoring of glass manufacturers and may impose tighter controls on online sales to prevent counterfeit products from reaching the public. Consumers are being urged to purchase only glasses that carry the ISO 12312‑2 certification and to avoid makeshift alternatives that could cause permanent damage.
