A total solar eclipse is set to be visible in April, but there’s a warning that eclipse glasses may become increasingly hard to find as the event approaches. The eclipse will be visible in 13 states on April 8, with a partial view in all others except Alaska and Hawaii. However, it’s crucial to ensure proper eye protection when viewing the eclipse to avoid potential vision damage.
According to Richard Tresch Fienberg, a senior adviser at the American Astronomical Society, reports of sellers running out of stock are expected to surface by mid-March 2024, and the situation is likely to worsen as the eclipse date approaches. This echoes the experience in 2017, where companies sold out of eclipse glasses in the weeks leading up to the ‘Great American’ solar eclipse on August 21st.
To safely view the solar eclipse, it is imperative to wear eclipse glasses or viewers that meet the international standard ISO 12312-2. Sunglasses, smoked glass, unfiltered telescopes, magnifiers, and polarizing filters are not suitable substitutes, as they can transmit dangerous levels of sunlight. Ronald L. Benner, president of the American Optometric Association, emphasized the importance of using approved eye protection to prevent potential harm.
However, there is a caveat to purchasing eclipse glasses, as counterfeit products have inundated the market. This poses a significant challenge for consumers in discerning genuine glasses from fraudulent ones. Experts advise inspecting eclipse glasses or handheld viewers before use and discarding them if they are torn, scratched, or damaged.
For consumers seeking reputable manufacturers and authorized vendors, a list is available to guide their purchase decisions. While the optometric association has not encountered unsafe eclipse glasses in the market, there have been instances of Chinese eclipse glasses bearing the name of a U.S. manufacturer, constituting fraudulent activity. The association refrains from endorsing companies suspected of selling counterfeit glasses, highlighting the need for vigilance when making a purchase.
Failure to use appropriate eye protection during the solar eclipse can lead to various symptoms, including loss of central vision, distorted vision, and altered color vision. It may take hours to days for individuals to realize the extent of the damage, underscoring the urgency of seeking optometric treatment for any related symptoms.
