Where to buy ISO 12312-2 certified eclipse glasses before August 12, 2026
As the August 12, 2026 eclipse approaches, only one purchasing rule matters: the ISO 12312-2 certification, which guarantees a filter blocking over 99.99% of visible light, UV, and infrared. Here is where to find them, at what price, and how to avoid nasty surprises — stock shortages are already being flagged by astronomy associations across Europe.
Comparison of retail options
Opticians
Optical chains are your most reliable source. Many national optician networks distribute free pairs or sell certified glasses at €2–5 each in the lead-up to the eclipse. Reliability is high, but stock is limited and you need to visit in person.
Pharmacies
Many pharmacies stock eclipse glasses ahead of the event (generally €2–5 a pair). Reliable, but supply is uneven: not all will have them, and rarely in large quantities.
Astronomy shops and science venues
Astronomy retailers and science museums sell certified models at €2–5. Quality is guaranteed, but the network is geographically limited — check your nearest planetarium or science centre.
Magazines and newsagents
Some astronomy magazines include a certified pair with their special eclipse edition: a good value two-in-one deal.
⚠ Caution
In France, one newsagent publication was withdrawn because its included glasses were non-compliant. Always verify the ISO 12312-2 marking on the arms.
Online
The only channel where you can order multiple pairs, delivered to your door, without depending on local store stock. It is also the most exposed to counterfeits on large marketplaces: buy only from specialist retailers clearly displaying the certification and manufacturer identity.

ISO 12312-2 marking (ideally ISO 12312-2:2015) and CE marking printed on the arms.
Manufacturer or distributor identity (name and address) present on the product or packaging — its absence is a warning sign.
Filter condition: no scratches, visible creases or micro-holes. Against a bright lamp, only a very faint image should appear.
Identifiable seller: on marketplaces, beware of third-party sellers with no history — during the 2017 American eclipse, entire batches of counterfeits were sold this way.
When should I buy?
Now. The same pattern repeats with every eclipse: demand explodes in the final ten days, physical stock runs out, and delivery times exceed the event date. Ordering in early July means you are equipped, can check your kit calmly, and have enough for the whole family — one pair per person, children included.
