Latest Announcement on Solar Eclipse Glasses: We Are Updating Our verify-glasses Page

expand_more

With the imminent arrival of the solar eclipse, we are intensifying our efforts to verify if the solar eclipse glasses sold on e-commerce platforms comply with legal safety requirements.

If you are about to purchase glasses or find that the brand you purchased is no longer on our verification list, we have prepared the following guide. We have noticed that many recent online listings do not display the manufacturer's or the EU responsible person's information correctly. To ensure your safety, use the following methods to check if your glasses comply with European Union regulations.

Safety Verification Table:

Verification Step What to Look For and EU Requirements Recommended Action
1. CE Certificate (EN ISO 12312-2) Check the product page or packaging to see if there is a CE certificate issued by an EU Notified Body confirming compliance with the EN ISO 12312-2 standard. The manufacturer's name and certificate number must be clearly visible. Do not buy if the seller has censored, pixelated, or covered key certificate information in the images.
2. EU-REP Information (EC-REP) Look for the Authorized Representative in the EU (EU-REP) information. According to EU market surveillance regulations, this is a mandatory requirement for manufacturers outside the European Union. Reject products that do not clearly indicate this entity. The EU-REP ensures there is a legally responsible party to claim against in case of product defects.
3. Manufacturer Consistency Compare the manufacturer's information detailed on the e-commerce product page with the information printed on the CE certificate. Avoid if they do not match. This discrepancy often indicates that sellers are abusing a supplier's certificate to sell a counterfeit or unverified batch.

Final Conclusion:

For solar eclipse glasses to be considered legal and safe under EU regulations, they must have a transparent CE certification and, for non-European brands, a clearly identified EU Representative (EU-REP). The lack of these elements means the product does not comply with the law and could put your eye health in serious danger. If the product you are viewing does not pass these three checkpoints, do not use it to observe the sun.

AliExpress's Response: An Absolute Lack of Responsibility

We have repeatedly tried to communicate with the AliExpress platform to warn them about the mass distribution of non-compliant personal protective equipment. However, their customer service directed us to their supposed legal compliance department, where we only received automatic responses generated by Artificial Intelligence. We were never able to contact a human manager to take charge of the matter. This lack of filters and human support demonstrates an extremely irresponsible attitude towards public safety.

Recommendation for the Public

These glasses, completely lacking any certification or quality control, can cause severe and permanent damage to your eyes (solar retinopathy).

We strongly advise against buying these types of products on AliExpress. If you have already purchased any of these glasses, we strongly advise you to contact the platform immediately to request a refund.

SAFETY ALERT: Evaluation of "Medical King" Eclipse Glasses According to ECLIPSE SEGURO Standards

expand_more
person Author: Antonio (Volunteer Editor, ECLIPSESEGURO.ES)

Transparency and Update Notice: As an independent, non-profit entity, ECLIPSE SEGURO does not accept financial compensation, sponsorships, or free samples from any manufacturer. Our evaluation is conducted under strictly objective criteria. The following verification is based on the information from the Amazon product page and the documentation available as of April 15, 2026. We acknowledge that sellers may modify their listings later, so our team of volunteers will conduct new verifications if the documentation is updated.

As volunteer editors of ECLIPSE SEGURO, our only commitment is your eye safety. We have subjected the "Medical King" brand eclipse glasses to our standard verification process to determine if they comply with the EN ISO 12312-2:2015 standard.

Compliance Summary: "Medical King" Brand

ECLIPSE SEGURO Criterion Standard Requirement Status of "Medical King" Infraction Detail
01. Laboratory Report Valid test issued by an accredited laboratory in the EU. ❌ Non-compliant Certificate issued by POCE (a laboratory in China, not accredited in the EU for this purpose).
02. Identification and Model Clear manufacturer information, CE mark, and matching model. ❌ Non-compliant The QR code in the manual leads to no information. False marketing claims ("NASA Approved").
03. European Representative Authorized Representative registered in the EU (for non-EU manufacturers). ❌ Non-compliant Total absence of a legal representative's data in Europe on the manual or packaging.
04. Blue Guide (European Union) Traceability and transparency in the supply chain. ❌ Non-compliant The certificate deliberately censors the "Applicant" and "Manufacturer" data.

Detailed Analysis of Irregularities

Medical King Amazon Listing

1. Invalid Laboratory Report in the EU

Our first evaluation criterion requires a valid test report demonstrating compliance with the EN ISO 12312-2:2015 standard, issued by an accredited laboratory based in the EU. The "Medical King" brand presents a certificate issued by Shenzhen POCE Technology Co., Ltd., an institution located in China. POCE does not have the authority as a notified body in the EU to issue this certificate and, according to our operational investigations, the agency itself advises against using this document as a basis for sales in the European market.

POCE Certificate
Detail of the POCE certificate where critical data is hidden, violating the traceability guideline.

2. Data Concealment and Violation of the Blue Guide

The product and its supply chain must fully comply with the trade regulations of the European Union's 'Blue Guide'. When analyzing the provided POCE certificate, we discovered that the "Applicant" and "Manufacturer" information has been deliberately erased. This tactic evades legal responsibilities and violates the principle of transparency essential for safe commercialization in Europe.

3. No European Representative and Instruction Issues

For manufacturers located outside the European Union, it is mandatory to have an Authorized Representative registered within the EU. "Medical King" completely omits this figure in its manuals. This means that if a user suffers eye damage, there is no responsible entity in European territory to claim against. Additionally, the QR code included in their instructions is empty, depriving the user of the mandatory inspection guide.

Amazon ASIN
Product details on Amazon showing the ASIN B0FD3J7DJ7.

4. Platforms and False Marketing

Selling on Amazon, TikTok, or TEMU does not exempt a product from complying with the law. "Medical King" listings use claims like "NASA 2024 approved". We warn our community that marketing is no substitute for rigorous independent laboratory testing.

Marketing claims
Marketing claims on the product listing ("NASA 2024") seeking to generate a false sense of security.

Health Warning: The Price of a Peek

As editors of ECLIPSE SEGURO, our conclusion is that "Medical King" glasses are NOT safe and present a serious risk of solar retinopathy.

When we look at the sun without adequate protection, ultraviolet rays damage the photoreceptor cells of the retina, specifically in the fovea. A recent study published in the Canadian Journal of Ophthalmology documented cases of permanent structural damage after the 2024 eclipse in people who looked at the sun without certified protection. Patients who observed the phenomenon for just 30 seconds, or covering one eye with their hand, suffered the loss of the ellipsoid zone and cellular-level damage (Henle fibers) resulting in irreversible blurred vision.

Consult the ophthalmological report from the University of Montreal here: 2024 Clinical Study.

Always Verify Your Equipment

Do not risk your vision with products of doubtful origin. If a product does not have the "Total Compliance" icon on our site, we do not recommend its use. Verify if your brand of eclipse glasses has passed our 4 criteria: eclipseseguro.es/verify-glasses.


Legal Notice: This report has been drafted by the volunteer editors of ECLIPSE SEGURO for informational and consumer protection purposes, based on the strict application of our 4 safety criteria to the public documentation displayed by the seller on the indicated date. This article does not constitute a binding legal opinion of the European Union. We recommend manufacturers to rectify any documentary deficiency to guarantee the traceability required by European regulations.

SAFETY ALERT: Evaluation of "Helioclipse" Eclipse Glasses According to ECLIPSE SEGURO Standards

expand_more
person Author: Antonio (Volunteer Editor, ECLIPSESEGURO.ES)

Transparency and Update Notice: As an independent, non-profit entity, ECLIPSE SEGURO does not accept financial compensation, sponsorships, free samples, or donations from any manufacturer. Our evaluation is conducted under strictly objective criteria based on the EN ISO 12312-2:2015 standard. The following verification is based on the information from the Amazon product page, user reports, and documentation available as of April 2026. We acknowledge that sellers may modify their listings later, so our team of volunteers will conduct new verifications if the documentation is updated.

As volunteer editors of ECLIPSE SEGURO, our only commitment is your eye safety. We have subjected the "Helioclipse" brand eclipse glasses to our standard verification process to determine if they comply with mandatory regulations. Following an exhaustive investigation based on consumer reports and our analysis of the documents provided by the seller, we have found serious irregularities and safety risks. Below is a clear summary of our documentary audit results:

Compliance Summary: "Helioclipse" Brand

ECLIPSE SEGURO Criterion Standard Requirement Status of "Helioclipse" Infraction / Compliance Detail
01. Laboratory Report Valid test issued by an accredited laboratory in the EU. ❌ Non-compliant No European laboratory report. The certificate shown is from the U.S. (ICS) and the manufacturer's name does not match the listing.
02. Identification and Model Clear information and correct standard printed on the glasses. ❌ Non-compliant Critical Danger: The glasses have the standard for regular sunglasses printed on them (ISO 12312-1) instead of the eclipse standard (ISO 12312-2).
03. European Representative Authorized Representative registered in the EU. ✅ Compliant The product displays information for an EU agent/representative on its packaging.
04. Blue Guide (European Union) Traceability, transparency, and commercial veracity. ❌ Non-compliant False advertising: Claims to be on the AAS safety list, but does not appear in their official registry. Inconsistency in manufacturer data.

Detailed Analysis of Irregularities

Helioclipse Listing
Screenshot of the "Helioclipse" product listing on Amazon.

1. Critical Danger: Incorrect Standard Printing (ISO 12312-1)

We have received multiple alerts and a PDF summary of consumer complaints indicating that this product does not comply with the required EN ISO 12312-2:2015 standard. When conducting our fact-checking based on reviews and real photographs shared by users, we verified that the glasses clearly have the standard "ISO 12312-1" printed on them.

What is the difference and the risk? The ISO 12312-1 standard is applicable to regular and fashion sunglasses for daily use. These glasses transmit thousands of times more light than permitted for looking at the sun and offer no protection against intense infrared radiation. On the other hand, ISO 12312-2 is the strict regulation specifically designed for direct solar observation filters. Using glasses with the 12312-1 standard to view an eclipse will invariably result in severe retinal damage in a matter of seconds.

Real photographs taken by users where the incorrect ISO 12312-1 standard print is clearly visible on the temples of the Helioclipse glasses.

2. Certification and Laboratory Irregularities

Our first criterion requires a report issued by an accredited laboratory in the EU. In the case of Helioclipse, the seller completely omits a European report. Instead, they display a test report from the US laboratory ICS Laboratories. Aside from not being an EU certifying body, we have detected a serious inconsistency: the manufacturer listed in the lab report does not match the declared manufacturer on the Amazon product details page. This break in traceability makes it impossible to guarantee that the evaluated glasses are the same ones being shipped to customers.

Screenshot of the ICS Laboratories report where the discrepancy in the manufacturer's name regarding the listing information is evident.

3. False Claim of AAS Approval

The seller actively promotes in their listing images and packaging that the product is endorsed by the American Astronomical Society (AAS). However, after reviewing the official registry, we confirm that, as of April 2026, the Helioclipse brand DOES NOT appear on the AAS safe vendors list. Promoting a non-existent certification is a violation of consumer trust and transparency regulations. To verify this, consult the official AAS list.

False AAS Claim
False advertising on the product packaging falsely claiming to have AAS approval.

4. Presence of European Representative

As the only point in favor, our checks indicate that the product packaging does include the information of an Authorized Representative in the EU. While this partially complies with an administrative requirement, it does not exempt the product at all from the critical safety flaws described above (invalid laboratory and incorrect protection standard).

Conclusion and Health Warning: The Price of a Peek

As editors of ECLIPSE SEGURO, our conclusion is irrefutable: The "Helioclipse" brand product presents a high risk and serious safety deficiencies. We strongly recommend NOT using these glasses for solar observation.

Looking at the sun with regular sunglasses (ISO 12312-1 standard) allows ultraviolet rays to irreparably damage the photoreceptor cells of the retina. A study documented by ophthalmologists at the Centre hospitalier de l'Université de Montréal (CHUM) published in the Canadian Journal of Ophthalmology detailed that, during the 2024 eclipse, exposure without the correct certified protection caused direct lesions in the patients' fovea. Affected individuals suffered irreversible structural damage, including the loss of the ellipsoid zone at the cellular level, which translated into spots in the visual field and permanent loss of visual acuity, even with exposures as short as 30 seconds.

To date, this manufacturer has no plan nor has provided instructions to recall the defective products from the market. We firmly believe that the public should not be responsible for the seller's defects and negligence, and we strongly recommend the brand to provide a comprehensive and transparent product recall plan as soon as possible.


Legal Notice: This report has been prepared independently by the volunteer editors of ECLIPSE SEGURO for the purpose of protecting public health and promoting transparency in the market. Our analysis is strictly based on the application of safety regulations to the documentation and photographic evidence publicly presented up to the indicated date. This article does not constitute legal advice nor a binding opinion from any official European Union authority. We recommend consumers to always verify products before use.

Detailed Explanation of EU Standards for Eclipse Glasses

expand_more

1. Commission Implementing Decision (EU) 2023/941 (Latest Publication) This is the latest implementing decision of the European Commission concerning harmonized standards for personal protective equipment (PPE), published in May 2023. The annex of this page explicitly lists the EN ISO 12312-2:2015 standard as an officially recognized EU standard.

Rigorous Explanation of EU Requirements: According to Article 14 of Regulation (EU) 2016/425, personal protective equipment conforming to harmonized standards published in the Official Journal of the European Union "shall be presumed to be in conformity with the essential health and safety requirements". By including this standard, the EU legally establishes the exact technical specifications that manufacturers must meet to ensure their products are considered safe for European consumers.

2. Implementation Communication of the EU PPE Regulation (EU) 2016/425: In previous official communications, the EU detailed that eclipse glasses complying with the EN ISO 12312-2:2015 standard must bear the CE marking. Compliance confers a presumption of conformity as of April 21, 2018.

3. Detailed Explanation of the EN ISO 12312-2:2015 Standard: Adopted globally, this standard imposes strict safety criteria:

ISO 12312-2 Transmittance Requirements
  • Scope and Applicability: It explicitly applies only to products without magnification intended for direct observation of the Sun. It does not apply to regular sunglasses or telescope filters.
  • Transmittance Limits: It strictly regulates the transmittance for UV, visible, and IR rays. The maximum luminous transmittance allowed matches a shade 12 welding filter, and the minimum matches a shade 15.
  • Material Quality: Filters must be completely free from visual defects such as bubbles or scratches.
  • Mandatory Labeling: Certified products must display specific information, including clear warnings that looking at the sun without appropriate filters can result in permanent eye injury.

The Total Solar Eclipse of August 12, 2026

expand_more

On August 12, 2026, a spectacular total solar eclipse will occur, marking the first totality in continental Europe since 1999.

The eclipse will begin its global path in the Bering Sea, cross the Arctic, Greenland, and Iceland, before sweeping across the Iberian Peninsula from west to east.

Total Eclipse Map

In Spain —widely considered the best place in the world to view this eclipse— the phenomenon will occur during its final phases just before sunset.

The path of totality will enter through Galicia, cross numerous provincial capitals including Oviedo, León, Burgos, Zaragoza, and Valencia, before finally ending in the Balearic Islands. The maximum duration of totality will be 2 minutes and 18 seconds.

Due to the low elevation of the eclipsed sun in Spain, experts recommend finding observation setups with a completely clear western horizon. This low angle provides an excellent opportunity for astrophotographers.

Adding to the excitement, the eclipse happens right before the peak of the Perseid meteor shower.

As always, viewers must never look directly at the Sun without adequate protection.

Expert Guide: How to Safely and Effectively Photograph a Solar Eclipse

expand_more

The main advice from experts for first-time viewers is surprisingly simple: put down the camera and simply observe the spectacle.

For those who still wish to capture the event, the primary rule is safety: Special-purpose solar filters must always remain on lenses during all partial phases.

  • Equipment: A DSLR or mirrorless camera with a telephoto lens of at least 300 mm (1000 mm recommended for details) and a sturdy tripod are needed.
  • Settings: Strictly use manual focus and secure the lens with tape.
  • Exposure: Total eclipses present a massive dynamic range that requires bracketing exposures.
  • Alternatives: Propped-up smartphones recording wide-field videos can capture the invaluable audio of crowd reactions.

The Price of a Peek: Retinal Damage After the 2024 Solar Eclipse

expand_more
person Author: Antonio (December 25, 2025)
Clinical evaluation of eclipse retinal injury

Observing a solar eclipse is a fascinating event, but doing so without proper, certified protective equipment can have devastating and permanent ocular consequences. After the April 2024 solar eclipse, clinical cases of solar retinopathy were confirmed, clearly illustrating the extreme danger of exposing eyes to solar radiation using unsafe methods or uncertified glasses.

A team of retina specialists from the Centre hospitalier de l'Université de Montréal (CHUM) thoroughly documented cases of patients who suffered permanent damage after observing the astronomical phenomenon without proper certified protective glasses. The first documented case is of a 34-year-old man who looked at the eclipse through a window for just 30 seconds. Twenty-five days later, he had to seek medical attention due to blurry vision and the appearance of spots in the visual field of both eyes.

The second case involved a 17-year-old girl who simply tried to protect herself by covering her right eye with her hand while looking at the eclipse; three weeks later, she consulted an ophthalmologist for persistent vision problems in her left eye.

The clinical damage caused by exposure to ultraviolet rays without adequate protection directly affects the fovea, which is the central part of the retina responsible for providing sharp and detailed vision. Dr. Fares Antaki, an ophthalmologist at CHUM, explains that the retina acts like a film that captures light, and looking at the sun without protection allows ultraviolet rays to destroy photoreceptor cells. This structural damage at the cellular level is usually irreversible.

Detailed clinical examinations revealed the true severity of the injuries suffered. In the 34-year-old man's case, tests showed a loss of the ellipsoid zone, accompanied by a subtle curvilinear column of hyperreflective Henle fibers in both eyes. As for the 17-year-old girl, examinations of her left eye showed an outer hyporeflective space, indicating the loss of the ellipsoid and interdigitation zone.

The most alarming aspect of these injuries is that, although a person's visual acuity may seem nearly normal immediately after exposure and short-term symptoms can be relatively mild, the lasting effects and anatomical damage to photoreceptor cells are permanent. Furthermore, these cases registered by the Association of Ophthalmologists of Quebec (AMOQ) likely represent only a fraction of the real problem, as many affected individuals might not have sought medical help after using poor quality products or not using protection at all.

These clinical findings strongly underscore why it is vital to strictly verify the safety credentials of any eclipse glasses. A simple peek of just a few seconds without proper certification is enough to cause irreparable vision damage.

What is an eclipse?

expand_more

A solar eclipse is an impressive astronomical event that occurs when the Moon aligns perfectly between the Earth and the Sun, casting its shadow on our planet and temporarily obscuring the Sun's light.

Depending on the exact alignment, observers can experience four different types of solar eclipses:

Eclipse Information
  • Total Solar Eclipse: Occurs when the Moon completely covers the disk of the Sun. Viewers must be located in the "umbra" to witness totality.
  • Annular Solar Eclipse: When the Moon is farthest from Earth (apogee), it appears smaller and leaves a bright "ring of fire" visible.
  • Partial Solar Eclipse: The Moon only covers a fraction of the Sun.
  • Hybrid Solar Eclipse: A very rare event. Due to the Earth's curvature, it transitions between being annular and total at different points along its path.
Hybrid Eclipse Transition

This geographic limitation makes witnessing a solar eclipse a particularly rare and exceptional experience.

Safety Tips

expand_more
Safe Observation Guide for Total Eclipse

Experts emphasize that observing the partially eclipsed Sun is only safe when using solar filters that strictly comply with the international EN ISO 12312-2:2015 standard. Regular sunglasses are never safe.

  • Inspect before use: If the viewer is scratched, torn, or damaged, it must be discarded immediately.
  • Proper placement: Put on your glasses while looking away from the Sun. If you wear prescription glasses, place the eclipse glasses over them.
  • Supervise children: They must be supervised at all times.
  • The "Totality" exception: The only safe time to remove your viewer is during the brief period of "totality".

Extreme Caution with Optical Devices: Never look at the Sun through an unfiltered camera or telescope, even if you are wearing eclipse glasses. The concentrated rays will burn the filter instantly and cause blindness or irreversible damage.

Maintenance: EN ISO 12312-2:2015 glasses in good condition can be reused indefinitely. Clean them only with a dry microfiber cloth. Never use water or solvents on cardboard viewers.
