In the early evening of Wednesday, August 12, 2026, across much of Europe, demand for certified solar eclipse viewing goggles reached unprecedented levels. Reports from multiple European countries indicated that supplies were rapidly depleting, with some retailers and institutions reporting complete shortages. The phenomenon was expected to be visible in parts of northern Europe, with the total solar eclipse observable along a path stretching from Spain through France and into Belgium, where the moon would cover nearly 90% of the sun’s surface. In Spain, where the path of totality stretched from the northern city of Oviedo to the island of Majorca, many distributors noted that their stock had been exhausted. The Madrid Natural History Museum, one of 30 scientific institutions participating in a government-led free distribution campaign, had given away two million pairs of certified protective eyewear. Despite this effort, some pharmacies in Madrid still had limited stocks, selling them at prices ranging from three to four euros per pair. In Brussels, the capital of Belgium, where the lunar coverage would reach 90%, most opticians reported having no remaining supply of certified eye protection. Some opticians who managed to secure a few pairs sold 100 pairs within just 30 minutes. On the Portuguese coast, the network Club da Visão, which includes over 600 opticians, also distributed free certified eye protection, offering one pair per person. However, even with repeated restocking efforts, the demand far exceeded available supplies. In France, where the eclipse would be partial, some pharmacies continued receiving new shipments, though they were quickly sold at significantly higher prices. On Monday, a Parisian pharmacy sold a pair of certified eclipse glasses for 5.95 euros. Philippe Besset, president of the French Federation of Pharmacists' Syndicates, stated that the level of demand had surpassed expectations. Just months earlier, suppliers had offered around 200 pairs per pharmacy, sufficient for approximately four million people. His pharmacy sold its entire order of 200 pairs within a week. Ophthalmologists have been actively warning the public against using non-certified alternatives, such as sunglasses, tinted glass, or homemade filters. In Spain, authorities removed six models of unapproved eye protection from sale due to the risk of eye damage. Direct observation of the solar eclipse without proper protection can cause irreversible vision loss, including blindness in severe cases. Dr. Darja Dobovšek Divjak, an ophthalmologist at the University Clinical Center in Ljubljana, explained that looking directly at the sun without protection leads to photochemical reactions in the lens, similar to focusing sunlight onto paper or wood, causing burns. She emphasized that only certified eye protection, meeting international standards such as ISO 12312-2, is safe for observing the eclipse. The shortage has led to concerns about counterfeit products flooding the market. According to reports from Euractiv, unverified items such as colored glass, foil, and even X-ray images have circulated, allowing harmful infrared and ultraviolet light to pass through. These are particularly dangerous when used to view the eclipse through cameras, telescopes, or binoculars without appropriate filters. Certified protective eyewear must have a minimum rating of DIN 12, ensuring adequate filtration. In Slovenia, where the partial solar eclipse will be visible, local ophthalmologists have warned that even brief exposure without protection can lead to serious consequences. Children are especially vulnerable, as their lenses collect more harmful rays. They are also less aware of the risks and often stare at the sun for longer periods. Additionally, children's eyes may not fit properly in adult-sized goggles, reducing their effectiveness. In some cases, parents might attempt to look around the edges of the goggles, further increasing the risk. As the eclipse approaches, locations with clear views of the sky have become highly sought after. In Slovenia, the best viewing spots include coastal areas like Piran, where the sun will be partially obscured by 84%. Astronomers recommend locations with a clear view to the east, such as the Triglav area, where the eclipse will be more dramatic. In Ljubljana, the tower on Rašica offers panoramic views, though capacity is limited. Dr. Bojan Ambrožič, a hobbyist astronomer, advises avoiding locations with poor visibility to the west, such as Šmarna Gora, which lacks a clear view of the horizon. Meanwhile, health professionals continue to emphasize the importance of proper eye protection. At the University Clinical Center in Ljubljana, three patients arrived seeking medical attention after experiencing blurred vision and a sensation of pressure in their eyes following direct observation of the eclipse. All three individuals had looked at the sun without proper eye protection. While none suffered severe damage, the incident highlights the ongoing need for public awareness campaigns regarding the dangers of unprotected solar viewing.
