Consumers are being warned not to use counterfeit or “knock-off” protective glasses to watch the eclipse, as organizers and retailers push only safety-certified eyewear. The warnings emphasize that improper glasses can fail to protect eyes during solar viewing.

Retail information across outlets indicates that certified eclipse glasses are in short supply online ahead of the event on Wednesday. Several reports say many sales listings are nearly exhausted, while some remaining options come with high delivery fees or long shipping times that may not guarantee arrival before the eclipse.

Across the coverage, the main differences are in emphasis and local detail: some outlets focus more on the near-sellout state of certified stock, while others highlight the potential cost and timing barriers created by delivery charges. All point to the same practical concern for consumers—verifying certification and ensuring glasses arrive in time for safe viewing.
