Eclipse glasses: ISO standard, CE marking and safe use
An eclipse does not make the Sun safe to look at. Eye protection should be selected on the basis of actual filter performance and traceable compliance documents, not merely a printed ISO or CE mark.
Updated 31 October 2026
What should you check?
ISO 12312-2
This international standard concerns filters for direct observation of the Sun. ISO 12312-2:2015 is the published edition as of this update; a second edition is at final draft stage but is not yet published.
CE marking in Europe
EU Regulation 2016/425 sets requirements for personal protective equipment. The manufacturer, model, applicable assessment and EU declaration of conformity must be checked.
Matching documents to products
Test reports, EU type-examination certificates and declarations of conformity must correspond to the model actually supplied. PDFs alone are not proof for an unrelated item.
Before every use
Inspect the filters
Check for tears, scratches, holes and loose filters. Discard damaged eyewear and follow the maker’s instructions.
Not for use through a telescope
Eclipse glasses must never replace the appropriate front-mounted solar filter required by a telescope, binoculars or camera.
Supervise children
Ensure children wear their solar viewers correctly during all partial phases.
