The Ayuntamiento de Guadalajara warns that at the Feria de la Salud around 200 eclipse glasses by Lionstar, model Lionstar LSP1, were handed out in Guadalajara on 6 July. According to the city, this is a model that Spanish consumer protection authorities have added to the Red de Alertas and ordered to be taken off the market. The glasses were distributed by the Colegio Nacional de Ópticos-Optometristas as part of the fair.
The Red de Alertas is run by the Ministerio de Derechos Sociales, Consumo y Agenda 2030 ; the Lionstar LSP1 model was added at the request of the Community of Madrid. The official warnings describe the risk as follows: the filter is so dark that users cannot see the image of the Sun and may naturally respond by briefly lifting or removing the glasses. During this unprotected moment, direct sunlight can reach the eyes and cause chemical or thermal damage to the foveal region of the retina. The professional association also points out that the damage results from looking without protection, not from wearing the glasses themselves.
The warning is linked to the solar eclipse on 12 Augustexpected in Spain. National and regional consumer authorities have examined several models of solar viewing glasses in recent days and issued warnings. For Guadalajara the city council emphasises using only tested products in good condition and strictly following official advice on safe viewing.
Attributed statements: The Ayuntamiento de Guadalajara urges people to “follow the safety recommendations for observing astronomical phenomena closely”. The Colegio Nacional de Ópticos-Optometristas stresses that a risk arises in particular if the glasses are removed or shifted while looking at the Sun.
Context and effects: The warning aims to prevent possible eye injuries in the run-up to the solar eclipse on 12 August. For organisers distributing information or promotional material, the case illustrates that products can still be deemed risky after distribution, requiring prompt precautionary measures afterwards. The municipal and official statements gave no information on confirmed injuries or case numbers.
