In historic instances, eclipse-viewers thought they had been watching the solar be eaten by wolves, a dragon or a demon.

There are a number of causes for this. First, our latest analysis reveals that buyers typically think about the fame of an internet retailer whereas judging a product’s high quality. Unscrupulous third-party sellers can benefit from this truth by promoting their wares by a good on-line market.

One other complication arises from the success companies supplied by some marketplaces, equivalent to Amazon, the place third-party sellers instantly ship their merchandise to the web retailer’s warehouse for delivery and dealing with. These types of success companies provide a little-known profit to retailers: If a product is working out of inventory, they’ll “borrow” from a third-party vendor’s stock.

Sadly, this additionally signifies that a client who agrees to purchase from one retailer may very well obtain merchandise—maybe counterfeit—from a third-party vendor. Whereas there aren’t statistics exhibiting how often this occurs, there’s proof it is a vital downside.

However these protections do not apply throughout the board. In actual fact, some counterfeit-prone manufacturers, equivalent to Birkenstock, refuse to promote their merchandise by some on-line retailers fully. That leaves a gap for counterfeiters, who have a tendency to supply the bottom costs.

That is why the American Astronomical Society recommends eclipse-watchers keep away from shopping for protecting glasses from the lowest-price sellers on on-line marketplaces. And we utterly agree. In spite of everything, counterfeit sun shades could be returned, however harm to your eyes is everlasting. In 2017, one California man sporting counterfeit eclipse glasses was left with retina harm.
