How to Spot Fake Solar Eclipse Glasses (2026 Safety Guide)

Why Fake Eclipse Glasses Are a Serious Risk

As excitement builds for the August 12, 2026 total solar eclipse, millions of people across Spain, France, the UK, and Europe will be looking for eclipse glasses.

Unfortunately, major solar events often attract counterfeit products.

Fake eclipse glasses may look identical to real ones but can fail to block harmful radiation. Looking at the Sun through unsafe lenses can cause permanent eye damage, known as solar retinopathy.

According to the NASA, only properly certified solar viewing filters are safe for directly observing the Sun.

What Makes Eclipse Glasses “Real”

Authentic eclipse glasses meet the ISO 12312-2 international safety standard.

This certification ensures that the lenses:

• block harmful ultraviolet light

• reduce infrared radiation

• filter intense visible sunlight

If you’re unsure what this certification means, read our full guide on what ISO 12312-2 certification is and why it matters.

5 Ways to Spot Fake Eclipse Glasses

1. No ISO Certification Label

If the glasses do not clearly say ISO 12312-2, do not use them.

2. Missing Manufacturer Information

Legitimate products include:

• manufacturer name

• contact details

• usage instructions

If this information is missing, that’s a red flag.

3. You Can See Through Them Indoors

When wearing real eclipse glasses indoors:

• you should not see anything except very bright lights

If you can see normal objects, they are not safe.

4. Scratches or Damage

Even certified glasses become unsafe if:

• lenses are scratched

• filters are punctured

• frames are damaged

Always inspect your glasses before use.

5. Unverified Online Sellers

Be cautious when buying from:

• unknown websites

• online marketplaces without reviews

• sellers without certification details

Fake eclipse glasses often appear online in the months leading up to major eclipses.

Why This Matters for the 2026 Eclipse in Europe

The 2026 total solar eclipse will be visible across parts of Spain and western Europe, making it one of the most anticipated astronomical events in recent years.

With millions of people preparing to watch, demand for eclipse glasses will increase rapidly.

This creates an opportunity for counterfeit products to enter the market.

If you are planning to view the eclipse from Spain, France, or anywhere in Europe, ensuring your glasses are genuine is essential.

When It Is Safe to Remove Eclipse Glasses

During the brief moment of totality, when the Moon completely blocks the Sun, it is safe to remove eclipse glasses and view the solar corona.

However:

• this phase lasts only a short time

• the moment sunlight reappears, eye protection must be worn again

According to the European Space Agency, proper eye protection is required at all times outside totality.

Where to Buy Safe Solar Eclipse Glasses

To safely enjoy the August 12, 2026 solar eclipse, it is important to use properly certified eclipse glasses.
