The Eclipse that Fueled Eyewear Demand: How Many Suffered Eye Damage?

The Eclipse and Blindness: The Economics of Certified Goggles

The demand for glasses to observe the solar eclipse reached 60 million units, according to data from optical stores, while available stock barely exceeded hundreds of thousands. The paradox is evident: millions wanted protection, but most could not secure it. Yet, many looked at the sun without any protection, trusting in ordinary sunglasses or the darkness of the phenomenon.

Eyewear Demand: 60 Million Units That Didn't Exist

The eclipse phenomenon triggered a demand for certified eyewear that the market could not meet. According to one optician, the phone had been ringing non-stop since the previous Friday, and demand was cited at around 60 million units, clearly inflated by resale. The actual stock was only a few hundred thousand. Platforms like Amazon also ran out of stock, and many optical stores posted 'Sold Out' signs. This scarcity led many to view the eclipse without proper protection, or to use conventional sunglasses that do not filter direct solar radiation. The resale of glasses became an impromptu business, with prices soaring on second-hand platforms.

The Real Risk: Retinal Burns Without Treatment

Certified goggles, no matter how good, do not allow viewing the sun for minutes. Experts warn that one can only look during certain seconds, and prolonged exposure can cause burns to the retina. These injuries do not hurt at the moment, but they can lead to irreversible vision loss. In fact, there is no treatment for retinal burns, and emergency services were reinforced due to the prediction of cases. One account recalls that during the total eclipse, which lasted 1 minute and 44 seconds, viewing without protection was possible, but during the partial phase, goggles are essential. However, many did not know this and stared intently for minutes. Some even used binoculars without proper filters, concentrating the sunlight and aggravating the risk.

Damage Estimates: Tens or Hundreds?

The projections regarding the number of affected individuals vary enormously. Some calculations suggested that between 50 and 100 people might suffer eye damage, while others estimated it would be 'one or two.' The reality is that, as of today, there are no official figures. What is known is that prolonged sun exposure without protection is a real risk, and the combination of eyewear scarcity and lack of knowledge about its correct use has left many vulnerable.

In parks, people were observed staring at the sun with goggles, while others removed them after only a few seconds due to suggestion. Confusion was widespread.

The question remains whether, next time there is an eclipse, people will learn their lesson or repeat the same pattern of frantic buying and imprudent exposure.
The economics of the eclipse has shown that demand can exceed supply, but also that information does not always arrive in time.
