From CEFCA, special emphasis is placed on the safety of solar eclipse observation. Direct viewing of the Sun without adequate protection can cause severe and irreversible eye damage. Safe observation is a matter of public health, and it is essential to follow the recommendations of authorities and experts.

The Importance of Approved Solar Eclipse Glasses

For direct observation of the eclipse, it is essential to use solar eclipse glasses that strictly comply with safety regulations. Special emphasis has been placed on this aspect due to the importance of preventing visual accidents.

Key Rules for Solar Eclipse Glasses:

• You must use Approved Solar Eclipse Glasses.
• Verify that the glasses have the CE Marking and comply with standard ISO 12312-2:2015. This is the only guarantee that they filter harmful solar radiation.
• It is crucial to understand that accidents affecting vision are very common during eclipses if proper protection is not used or if it is not approved.
• For direct observation of the eclipse, only glasses with CE approval and ISO 12312-2:2015 certification will be accepted.
• Never combine the use of eclipse glasses with binoculars, telescopes, or other optical instruments without specific certified solar filters for them! The concentration of light will instantly damage your eyes.

Safe Observation Alternatives (without Glasses):

If you do not have approved glasses, a safe way to observe the phenomenon indirectly is by projecting the image of the Sun. A simple method is through the natural pinhole camera effect: the eclipse is reflected in the shadows projected by small openings, such as those formed between the leaves of trees, creating multiple images of the eclipsed Sun on the ground.

Important Warnings:

• Pay special attention to children. They are particularly prone to looking at the Sun without protection due to curiosity or lack of knowledge.
• Do not trust just any seller or generic online platform (like Amazon) or brands of unknown origin (uncertified Chinese brands). Purchase glasses only through trusted distributors who guarantee the authenticity of the approval.
• Currently, the estimated cost of approved glasses is around €4, but keep in mind that the number of certified manufacturers is limited. We recommend being alert for authorized points of sale that are announced.
• It is expected that there will be a distribution of approved glasses to municipalities by the national deputation (or competent authority). Stay informed through your local official channels.

Environmental Safety and Access Restrictions:

• The eclipse coincides with a period of extreme risk of forest fires and high temperatures[cite: 11].
• In the event of a Red or Red Plus Alert, the Government of Aragon may prohibit access to forest areas and suspend any public events in the natural environment[cite: 21, 22, 29, 30, 31, 32].
• Organizing gatherings in protected natural spaces or within a radius of less than 400 meters from them is prohibited[cite: 19].
• It is strongly recommended to observe the eclipse from the urban area or its immediate surroundings to guarantee safety and access to basic services[cite: 33, 39].
• Follow the instructions of the authorities regarding the use of fire and access to trails on the dates close to the event[cite: 12, 13].
