When a solar eclipse approaches, it's tempting to grab any pair of eclipse glasses that looks the part. But while genuine glasses let you experience nature's spectacle safely, counterfeits still flood the market, and the risks are real: permanent eye injury from looking at the sun even briefly. As competition heats up before major celestial events, learning to recognize fakes and insist on true standards is essential.
Why Authenticity Is More Than a Label
The difference between safe eclipse glasses and unsafe ones isn't just a matter of branding; it's rooted in rigorous optical science. The protective solar film must block a precise, verified amount of harmful light—otherwise, it's simply not safe. Trusted sources like the Planetary Society and NASA regularly warn that the market is rife with convincing fakes. So how can you confidently tell the good from the bad?
Check for Real Certification, Not Just Letters
The most reliable cue is clear certification. In Europe, look for “EN ISO 12312-2:2015” and the CE mark. For the US, “ISO 12312-2:2015” signifies conformity with rigorous safety standards. Don't just look for these codes and inspect how they're printed. Trustworthy glasses display crisp type, not smeared or stickered labels, plus a batch or lot number you can trace. To cross-check vendors, examine the American Astronomical Society’s ISO overview or their regularly updated approved vendor list.
About Silver-Black Filters and Why They’re Safer
Intriguingly, the front filter should look like a mirror—gleaming silver from the outside, solid black from the inside. This “Silver-Black” construction isn’t a feature for connoisseurs; it’s the global norm for certified solar viewers. The AAS and manufacturer pages like Absolute Eclipse confirm this standard. The metalized layer reflects harmful rays before they reach the eyes, while the opaque black interior absorbs stragglers.
At Absolute Eclipse, every pair uses this advanced filter and without passing the cost to consumers. Our margin is kept intentionally low, prioritising safety and transparency over marketing.
Why Coverage and Comfort Make All the Difference in Eclipse Glasses
We specifically have increased the size of our glasses to fully cover the face, making our glasses superior in this aspect. It's low cost solution which significantly improves the safety of our glasses, whilst cheap imports are attempting to keep their margins high by saving on the material. Reasoning behind this is that with our shape on standard pre-cut sheet you can only fit 8 glasses, whilst their smaller frames easily fit 10 or maybe even more.
Look for sturdy glasses that wrap around the eyes fully or use a rectangular format. Gaps near the temples or irregularly cut shapes can let in stray sunlight. Well-made eclipse glasses aren’t just protective, they feel reassuringly solid. Outlets like BBC Sky at Night Magazine break down what quality eclipse glasses look and feel like if you want a reputable second opinion.
Where You Buy Is As Important As What You Buy
Online marketplaces and pop-up sellers are magnets for counterfeits. The safest route: buy from astronomy retailers reviewed by organizations like the American Astronomical Society or leading science publishers. We batch-track every product sold at Absolute Eclipse, so customers can confirm authenticity. Want to investigate other vendors? Start with the AAS supplier list and check reviews on established science media sites.
Price Signals: Why Bargains Are a Warning Sign
Genuine eclipse glasses cost a bit more—an unavoidable consequence of precise manufacturing, lab tests, and compliance. If the price is too good to be true, the risk of substandard (and unsafe) materials goes up. As Eclipse23 points out, the cheapest eclipse glasses usually cut corners on the very processes that guarantee safety.
Our commitment is straightforward: offer Silver-Black filtered glasses at a fair price, ensuring peace of mind with every purchase.
Spotting Red Flags Before You Buy
- Missing, unofficial, or poorly printed certifications
- No batch or lot tracking, and vague vendor answers
- Flimsy construction, uneven edges, or odd shapes
- You can see household lights or scenery through the filter (only the sun’s disk should be visible)
- Unfamiliar websites or sellers who avoid questions about product origin
Resources like the NY Post's eclipse safety guide and EclipseGlasses.com’s safety page go deeper into visual and documentation red flags.
Here I found an user u/Boohoo622 from r/Astronomy showing an example of BAD glasses:
Thats not it should look, if yours look like this then don't risk it.
Easy Ways to Test Your Eclipse Glasses at Home
Before viewing any eclipse, scrutinize your glasses for scratches, distorted filters, or poor fit. Look at a bright lamp indoors—only the brightest filament might be faintly visible, otherwise everything else should be opaque. Review safety tips directly from University of Rochester, Eclipse23, and through our own knowledge center.
What If You Suspect a Fake?
If any doubts remain, err on the side of caution. Don’t use them for solar viewing. Alert the seller, report the listing to consumer protection agencies, and share your experience—other eclipse viewers could be at risk. Modern consumer safety depends on collective vigilance and open reporting.
The AAS's public warnings and guidance from the Planetary Society provide step-by-step advice for what to do next.
