• Use only approved sunglasses or visors that comply with ISO 12312-2 for direct observation.
• Do not use conventional sunglasses, X-rays, smoked lenses, photographic negatives or homemade filters, as they do not guarantee safe protection.
• In activities with schoolchildren or large groups, prioritize indirect observation methods, such as pinhole projection, which allows you to enjoy the eclipse safely.

In addition, the College of Opticians-Optometrists of the Valencian Community makes specific information, recommendations and informative material available to citizens, educational centres and public administrations through its website www.coocv.com/eclipse
