Best Eclipse Glasses for Spain's Eclipses
Eclipse glasses are the #1 essential item for watching a solar eclipse. Here's what you need to know and our top picks.
Critical Safety Information
Use only viewers that conform to ISO 12312-2 and come from a reputable manufacturer or authorised dealer. A printed ISO claim is not proof by itself. Discard viewers that are scratched, punctured, torn or separated from their frames; compliant viewers do not expire merely because they are more than three years old unless the manufacturer says otherwise.
What to Look For
- ISO 12312-2 conformity — supported by accredited testing, not merely printed on the viewer
- Verifiable manufacturer and seller — confirm that the dealer is authorised by the manufacturer
- Trusted source — IGN and the American Astronomical Society publish safety guidance and vetted suppliers
- No scratches or damage — inspect before each use
Vetted Manufacturers to Look For
The AAS currently lists the manufacturers below among suppliers whose solar viewers have satisfied its vetting requirements. A marketplace result is not enough: buy directly from the manufacturer or confirm that the seller is publicly identified by that manufacturer as authorised.
American Paper Optics / Eclipser
AAS-listed manufacturer. Confirm that the specific seller is authorised by American Paper Optics and inspect the viewers on arrival.

How Many Do You Need?
We recommend at least 2 pairs per person — one primary pair and one backup in case of damage. If traveling with a group, buy a 10-pack to share. Eclipse glasses are lightweight and inexpensive — it's worth having extras.
Can I Buy Eclipse Glasses in Spain?
Eclipse glasses will likely be available at major optical shops, science museums, and tourist areas near the path of totality closer to eclipse day. However, we strongly recommend buying in advance — demand always exceeds supply near eclipse time, and quality control can be an issue with last-minute vendors.
