Looking ahead to the next solar eclipse on August 12, something as important as find a good location to see it is to get hold of good approved glasses. X-rays and photographic negatives are not valid, as has traditionally been said. It is also not safe to look at the eclipse with conventional sunglasses.
Such acts, such as looking with the naked eye, can cause serious eye problems. This is something they know a lot about. ONCE. That’s why, they just launched next to the Ministry of Science, Innovation and Universities of the Government of Spain a campaign aimed at raising awareness about the importance of protecting eyesight at these types of events. And since there is no better way to raise awareness than by giving access to solutions, an important part of the campaign will be the distribution of 2 million free eclipse glasses throughout the country.

Other initiatives
The coupon for August 12, 2026 from the ONCE draw will be dedicated, as it could not be otherwise, to the solar eclipse. It is another of the initiatives that have emerged from this project between ONCE and the Ministry of Science, but not the only one.


The agreement was signed yesterday at the National Museum of Science and Technology of Spain (MUNCYT) in A Coruña. The signatories were the Secretary of State for Science, Innovation and Universities, Juan Cruz Cigudosa, and the first vice president of Institutional Coordination, Solidarity and External Relations of the General Council of ONCE, Alberto Durán.
Together, they announced the initiative to distribute eclipse glasses and sell a special coupon, but also many other activities. And with this signature, it has been decided to incorporate the ONCE Social Group into the meetings of the Interministerial Commission for the preparation, organization and coordination of actions related to the Trio of Eclipsesas well as to provide resources and educational materials that can be adapted, to guarantee the inclusion and cultural development of people with visual disabilities in particular and other disabilities. As Alberto Durán explained during the presentation, his goal is that after the eclipse no more people arrive at ONCE with vision problems. For this, awareness is a key point.
Guaranteed approval
To check that eclipse glasses are suitable, they must be approved according to the standard. EN ISO 12312-2:2015 and have the CE seal. The positive part is that these are distributed by two totally reliable institutions, such as ONCE and the Ministry of Science, so it is guaranteed that they have said seal. It is a nice initiative with which ONCE wants its clients to be very well protected in the face of the astronomical event of the year. And the best thing is that, well stored to avoid scratches or deterioration Otherwise, they can also be used to the solar eclipses of 2027 and 2028. An exciting time is coming for astronomy lovers in our country. Let’s enjoy it with protection.
