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.”

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.
