# Total solar eclipse 2026: Safety and security risks > Live situation record from CLSTR: https://clstr.news/situations/safety-warnings-for-2026-european-solar-eclipse > Updated: 2026-08-11T14:38:57.000Z. Sources: 117. Developments: 4. The total solar eclipse on 12 August 2026, visible across Greenland, Iceland, northern Russia, Spain, and Portugal, has triggered significant security and safety measures. In Spain, the event is expected to draw up to 6 million visitors, generating approximately 342 million euros in expenditure. To manage this, authorities have deployed over 35,000 security personnel to monitor crowds and high forest fire risks. Security experts have highlighted multifaceted threats, including terrorism, violent radicalization, and cybersecurity issues. Cybersecurity expert Selva Orejón warns that the primary threat may be “psychological warfare through disinformation,” as surges in information searches create openings for fake websites and AI-driven misinformation. Furthermore, analysts suggest that the combination of large crowds, disorientation from sudden light changes, and collective suggestion may increase vulnerability to theft and other criminal activities. Eye safety remains a critical priority. Spanish consumer authorities have recalled seven specific models of eclipse glasses—including brands Lionstar, ECP Eye Care Professional, Pelispan, Homanaje, Orro, Opticalia, and Mó de Multiópticas—due to injury risks. These models were flagged because their filters are excessively dark, which may cause users to remove or shift the glasses, leading to direct radiation exposure and irreversible retinal damage. In response, the Community of Madrid implemented a special medical protocol for August 12 and 13, deploying ophthalmology specialists to emergency departments. Medical experts warn that symptoms of solar retinopathy, such as dark spots or blurred vision, may not manifest until 4 to 12 hours after exposure. ## Claims - Authorities have ordered the withdrawal of six solar eclipse glass models due to eye injury risks. (disputed by 15 sources) - The defective glasses can cause chemical or thermal lesions in the retinal cells. (corroborated by 16 sources) - The defective filters are excessively dark, preventing users from locating the solar disk and causing them to expose their eyes to direct radiation. (corroborated by 15 sources) - FACUA warns that the irregularities detected in these six models could also be found in more products marketed or distributed in recent months. (corroborated by 6 sources) - The General Council of Pharmaceutical Colleges and the General Council of Opticians and Optometrists have released guides for eclipse observation. (corroborated by 3 sources) - Eclipse glasses must have security certifications such as ISO 12312-2:2015 or CE marking. (corroborated by 3 sources) - Using homemade filters like X-rays, CDs, or analog film poses a risk of irreversible retinal damage. (corroborated by 3 sources) - Standard UV-protective sunglasses are insufficient and dangerous for direct solar observation during an eclipse. (corroborated by 3 sources) - Observing the sun through cameras, binoculars, or telescopes without appropriate filters can damage vision and destroy device sensors. (corroborated by 3 sources) - The Guardia Civil seized nearly 100 units of non-compliant eclipse glasses in Cantabria.
