According to manufacturers and retailers, demand for solar eclipse glasses has skyrocketed, partly driven by increased public interest and online searches, such as ‘where to get eclipse glasses’ and ‘solar eclipse London.’ Several vendors have sold out of certified glasses, with some reporting delays in restocking. The American Astronomical Society (AAS) and other agencies have reiterated that only glasses meeting the ISO 12312-2 safety standard are safe for direct solar viewing. You can explore related information in the interactive eclipse map. Experts warn that using unverified or homemade filters can cause permanent eye damage. The shortage has also led to a rise in counterfeit products, with authorities warning consumers to verify the authenticity of their glasses before use.

Risks of Unsafe Solar Eclipse Viewing Practices
This shortage and the proliferation of counterfeit glasses pose a significant safety risk to viewers. Eye damage from looking directly at the sun without proper protection can be immediate and irreversible. The issue underscores the importance of using certified equipment and raises awareness about the dangers of unverified products. Public health agencies emphasize that improper viewing can lead to conditions such as solar retinopathy, making this a matter of urgent safety concern for millions planning to observe the eclipse.

Rising Public Interest and Historical Viewing Trends
Interest in solar eclipses has grown globally, driven by recent astronomical events and increased media coverage. The last major eclipse visible in parts of Europe and North America occurred in 2017, sparking widespread public viewing. The upcoming eclipse, expected in October 2023, will be visible in parts of the United States, South America, and Africa, prompting many to purchase certified glasses in advance. Historically, shortages of eclipse glasses have occurred before major events, often exacerbated by supply chain disruptions and counterfeit products entering the market.
“We advise consumers to purchase from reputable vendors and verify the certification of their eclipse glasses before use.”
— Consumer Safety Agency spokesperson, Mark Reynolds
Extent of Global Supply Shortages and Counterfeit Risks
It is still unclear how widespread the supply shortages will be across different regions, and how effectively authorities can curb the sale of counterfeit glasses. The full impact of these shortages on public viewing plans remains to be seen, especially in less-developed markets where supply chain issues are more acute.
Restocking Efforts and Public Safety Campaigns Before the Eclipse
Manufacturers and retailers are working to increase supply and authenticate products. Public safety agencies plan to launch awareness campaigns emphasizing the importance of certified glasses. The next major eclipse in October 2023 will serve as a critical test of these measures, with authorities monitoring supply and safety compliance closely.
