Eclipse Glasses Recalled: How to Check If Yours Are Safe 2026

Eclipse glasses have become a hot commodity in recent weeks, with millions rushing to buy proper eye protection for the spectacular astronomical event this Wednesday. But as with any massively sold product, some brands have had to recall entire batches due to manufacturing defects. The Spanish government has now issued a recall for Lionstar's LSP1 model after a problem was detected in its protective filter.

Why the Lionstar Eclipse Glasses Were Recalled

The issue with these eclipse glasses is not that they fail to protect—rather, they protect too much. The filter is so extremely dark that users cannot see anything through them. This creates a dangerous temptation to peek over the top of the glasses to catch the spectacle, a gesture that can damage the retina.

Authorities stress that it's not just about visibility; the glasses are actively dangerous. When users can't see through the lenses, they are more likely to remove them or look around them, exposing their eyes to harmful solar radiation. The recall was triggered through the Spanish Ministry of Consumption's Alert Network, which immediately ordered the withdrawal of these glasses, primarily sold in pharmacies and online optical stores.

How to Check If Your Eclipse Glasses Are Affected

If you purchased eclipse glasses recently, especially the Lionstar LSP1 model, you should verify whether they are part of the recalled batch. The recall affects glasses sold mainly in pharmacies and online optical shops in Spain, but with global supply chains, similar products could have reached other markets.

Check the packaging for the model number LSP1 and the brand name Lionstar. If you have these glasses, do not use them. Return them to the point of purchase or dispose of them safely. The Spanish Ministry of Consumption has published the recall notice on its website, and you can also contact the retailer for confirmation.

What Makes Eclipse Glasses Safe or Unsafe

Safe eclipse glasses must meet the ISO 12312-2 international standard, which ensures they block harmful ultraviolet and infrared radiation while still allowing you to see the sun comfortably. The Lionstar LSP1 glasses failed not because they lacked filtration, but because the filter was excessively dark, creating a usability hazard.

When glasses are too dark, users instinctively try to look around them, which defeats the purpose of eye protection. Proper eclipse glasses allow you to view the sun without squinting or feeling the need to remove them. They should also be free of scratches, punctures, or tears, and should fit snugly on your face.

Other Eclipse Glasses Recalls and Safety Alerts

The Lionstar recall is not an isolated incident. In recent years, several brands have faced similar actions due to substandard products. During the 2017 solar eclipse in the United States, Amazon and other retailers had to recall glasses that were falsely labeled as ISO-compliant.

In 2024, with another major eclipse crossing North America, authorities in multiple countries have stepped up inspections. The Spanish alert network has been particularly active, flagging products that do not meet safety standards. Consumers are advised to purchase glasses only from reputable vendors and to check for the ISO 12312-2 certification on the label.

What to Do If You Have Recalled Glasses

If you own Lionstar LSP1 eclipse glasses, stop using them immediately. Return them to the retailer for a refund if possible, or dispose of them in a way that prevents others from using them.
