It has been seven years since the last solar eclipse in the US, and a total solar eclipse will take place on Monday, April 8, 2024. Approximately 31 million Americans who live in a specific area from Maine to Texas will be able to view the moon totally block the sun. Others will witness a partial solar eclipse. According to NASA, approximately 99% of US residents will see some form of the eclipse.
It is critical, therefore, to ensure proper eye protection during the eclipse, with certified solar eclipse glasses. Viewing a solar eclipse without the appropriate protection can lead to serious eye damage or even blindness, a condition known as solar retinopathy. Eclipse glasses are specifically designed to block out a significant amount of sunlight, making them crucial for anyone looking directly at the eclipse, except during the brief period of totality when the moon fully covers the sun.
For those unable to obtain eclipse glasses, alternative viewing methods such as pinhole projectors or a camera obscura offer safe ways to enjoy the spectacle. However, it’s vital to avoid using regular sunglasses, telescopes, binoculars, or unfiltered cameras as these do not provide adequate protection.
With the demand for eclipse glasses surging, the risk of counterfeit products looms large. The American Astronomical Society (AAS) warns of the market flooded with fake glasses that fail to offer the necessary eye protection. To counteract this, the AAS recommends sourcing glasses from reputable vendors listed on their website, cautioning against relying solely on the ISO 12312-2 international safety standard due to the prevalence of fraudulent claims.
In a bid to make the eclipse accessible to all, over 13,000 public libraries across the U.S. are distributing 5 million free eclipse glasses. For those with glasses on hand, verifying their safety involves a simple test: when worn, only the sun or a similarly intense light source should be visible, and any damage or scratches on the glasses render them unsafe for use.
As the eclipse draws near, the excitement is palpable, but so is the need for caution. With the right preparations, everyone can safely enjoy one of nature’s most awe-inspiring displays.
