Solar Eclipse Safety: Why Certified Eclipse Glasses Matter
On August 12, 2026, millions of people across Europe will experience one of the most spectacular astronomical events of our lifetime — a total solar eclipse.
During a total solar eclipse, the moon passes directly between Earth and the sun, temporarily blocking sunlight and turning day into twilight. For many people, it will be their first and only opportunity to witness this rare celestial event.
But there is one critical rule everyone must follow:
Never look directly at the sun without certified solar eclipse glasses.
Even when the sun is mostly covered by the moon, its radiation remains powerful enough to cause serious and permanent eye damage.
Understanding solar eclipse safety and using properly certified eclipse glasses is essential for safely enjoying the event.
What Happens if You Look at the Sun Without Protection?
Looking directly at the sun without proper eye protection can cause a condition known as solar retinopathy.
Solar retinopathy occurs when intense sunlight damages the retina — the light-sensitive tissue at the back of the eye responsible for vision.
Unlike other injuries, retinal damage often happens without immediate pain. Many people do not realize harm has occurred until hours later when they experience symptoms such as:
-
blurred vision
-
blind spots
-
distorted images
-
reduced color perception
In severe cases, the damage can be permanent.
Because of this risk, astronomers, scientists, and health authorities worldwide strongly recommend using certified solar eclipse glasses whenever viewing the sun during an eclipse.
What Makes Solar Eclipse Glasses Safe?
Not all dark glasses are safe for looking at the sun.
Regular sunglasses — even extremely dark ones — are not designed to block the dangerous radiation produced by the sun.
Safe solar eclipse glasses must filter nearly all visible light and harmful radiation while still allowing the sun to be viewed safely.
Certified eclipse glasses must:
-
Block 99.99% of visible sunlight
-
Block 100% of harmful ultraviolet (UV) radiation
-
Block dangerous infrared radiation
-
Be tested and manufactured under strict safety standards
The globally recognized standard for safe solar viewing is:
EN ISO 12312-2:2015 – Filters for Direct Observation of the Sun
This standard specifies the optical requirements that solar viewing filters must meet in order to protect human eyesight.
Only eclipse glasses tested against this standard should be used for direct observation of the sun.
Our EU Type-Examination Certificate
To ensure the highest level of safety and transparency, the eclipse glasses used by The Fin Whale Eclipse Project are supported by an official EU Type-Examination Certificate.
This certification confirms that the product was independently evaluated and meets the strict requirements of the Personal Protective Equipment Regulation (EU) 2016/425
The certification process verifies that the product complies with the essential health and safety requirements required for protective eyewear.
Key information from the certificate includes:
-
Product: Solar Eclipse Glasses
-
Model: FWE01
-
Manufacturer: 15004306 Canada Inc.
-
Certification body: CCQS Certification Services Limited
-
Applicable standard: EN ISO 12312-2:2015
The glasses are classified as Category II Personal Protective Equipment (PPE) designed specifically for direct solar observation
CE-Certificate
This means the product’s design, materials, and optical filters were independently assessed before being approved for sale in the European market.
Optical Safety Performance
The certification testing also measures how much sunlight passes through the eclipse lenses.
The results show extremely low transmission levels, ensuring safe solar viewing:
-
Luminous transmittance: approximately 0.00027%
-
Solar UVA transmission: 0.00001%
-
Solar UVB transmission: 0.00001%
-
Solar infrared transmission: approximately 0.12%
These measurements confirm that the lenses block the overwhelming majority of harmful solar radiation while allowing the sun to be safely viewed.
How to Tell if Solar Eclipse Glasses Are Safe
Unfortunately, during major eclipse events counterfeit or unsafe glasses sometimes appear on the market.
To ensure safe viewing, trusted solar eclipse glasses should always include the following features:
ISO Certification
The glasses should clearly state compliance with ISO 12312-2.
CE Marking (Europe)
The CE mark indicates the product complies with European safety regulations.
Manufacturer Identification
Legitimate eclipse glasses include the name and contact information of the manufacturer.
Traceable Certification
Reputable products are supported by documentation such as an EU Type-Examination Certificate confirming independent testing.
If eclipse glasses do not clearly display these details, they should not be used for solar viewing.
Why Regular Sunglasses Are Dangerous
Many people assume that dark sunglasses will provide enough protection during an eclipse.
This is not true.
Even extremely dark sunglasses typically block only a small fraction of the sun’s radiation.
They are designed to reduce brightness for comfort — not to protect against direct solar observation.
Without proper solar filters, harmful radiation can pass through the lenses and damage the retina.
Only certified eclipse glasses designed specifically for solar viewing provide adequate protection.
Safe Solar Eclipse Viewing Tips
To safely enjoy the August 12, 2026 total solar eclipse, follow these simple safety guidelines.
Always Use Certified Eclipse Glasses
Wear certified solar eclipse glasses whenever looking directly at the sun.
Inspect Your Glasses
Do not use glasses that are scratched, damaged, or punctured.
Supervise Children
Children should always be supervised when using eclipse glasses.
Remove Glasses Only During Totality
If you are inside the path of totality, glasses can be briefly removed when the sun is completely covered.
Put Glasses Back On Immediately
As soon as sunlight begins to reappear, eclipse glasses must be worn again.
Following these steps ensures the eclipse can be experienced safely and comfortably.
The Fin Whale Eclipse Project
The Fin Whale Eclipse Project combines the wonder of astronomy with a commitment to ocean conservation.
The project helps raise awareness about the protection of the North Atlantic fin whale, the second-largest animal on Earth.
A portion of project proceeds supports initiatives focused on marine conservation and protecting whale migration routes.
By choosing certified eclipse glasses from this project, you help support:
-
safe solar observation
-
transparent product certification
-
ocean conservation efforts
Prepare for the 2026 Total Solar Eclipse
The 2026 total solar eclipse will be one of the most widely visible eclipses across Europe in decades.
Demand for certified eclipse glasses is expected to increase dramatically as the event approaches.
Preparing early ensures that you and your family can safely enjoy this once-in-a-generation astronomical event.
