With certified glasses sold out, experts warn against unsafe viewing methods and counterfeits
Category: Arts & Culture
As excitement builds across the UK for the solar eclipse on August 12, 2026, a frantic rush to secure protective eyewear is underway. This celestial event will likely be the most spectacular since 1999, with the Moon set to obscure over 90% of the Sun between 6:17 PM and 8:06 PM. Many are scrambling to find proper solar eclipse glasses, but high street stores are rapidly running out of stock, leaving many would-be viewers in a bind.
Online shoppers face similar challenges; those lucky enough to find a pair are often met with disappointing delivery timelines, with some orders not expected to arrive until after the eclipse. The Royal Observatory Greenwich has confirmed the shortage, stating, "We have sold out of solar eclipse glasses, both online and in our shops, due to an unparalleled volume of orders." Ordinary sunglasses are not safe for viewing the eclipse, and experts are urging the public to act quickly.
The upcoming eclipse on August 12 is not just any astronomical event; it's a rare opportunity for the UK, which hasn’t seen such a high percentage of solar coverage since the total eclipse in 1999. Neill Sanders, founder of Go Stargazing and the UK coordinator of Astronomers Without Borders, noted that a lack of planning has contributed to the current frenzy. “I’m getting loads of calls, text messages, emails with people asking ‘Do you have some glasses?’” he said. “Everyone’s suddenly realizing we need glasses for Wednesday.”
Sanders imported 300,000 pairs of eclipse glasses from the US, of which 100,000 were distributed at discount prices to astronomy clubs and community groups. Yet, for many, this effort came too late, and demand continues to outstrip supply. The situation has led to long queues at various retailers, with reports of people waiting in line at the National Maritime Museum in Greenwich to snag a limited number of available glasses.
Experts stress the importance of using only certified eclipse glasses that comply with the ISO 12312-2 standard. These glasses are specially made to block harmful solar radiation, and anything less can lead to severe eye damage. Mohamed Elalfy, president of the Royal College of Ophthalmologists, warned, “Looking directly at the Sun during a solar eclipse can cause damage to the retina, potentially damaging the cells responsible for sharp central vision.”
Symptoms of eye damage may not appear until hours after exposure, including blurred vision and central blind spots. Kyla Black, director of optical practice at Boots Opticians, emphasized the need for caution, especially for children. “If you’re purchasing specially made eclipse glasses, make sure to double-check that they are undamaged before use, as even a glimpse of damage could have an impact on your eyesight,” she said.
With the rush for eclipse glasses, buyers are being warned against counterfeit products that do not meet safety standards. Tania de Sales Marques, senior astronomer at the Royal Observatory Greenwich, cautioned, “The only safe way to look directly at the Sun is by using certified eclipse glasses or a properly fitted solar filter on a telescope or binoculars.” Scammers may attempt to capitalize on the demand, selling fake glasses that could lead to permanent eye damage.
For those who cannot secure certified glasses in time, there are alternative methods for safely viewing the eclipse. Jake Fisher, astronomer at the Royal Observatory Greenwich, suggested using household items like a colander or a piece of paper with a small hole poked in it to project the eclipse onto a flat surface. “Don’t look at the sun itself but instead at the shadow that’s being produced; you should be able to see the shape of the eclipse within it,” he explained.
The eclipse will begin across the UK around 6:17 PM, peaking just after 7:10 PM. Depending on the viewer's location, the Moon will cover between 90% and 96% of the Sun. Major cities like London, Cardiff, and Birmingham are expected to experience nearly complete coverage, making this a prime opportunity for stargazers. For those unable to find glasses, the Royal Observatory Greenwich will livestream the event, allowing viewers to enjoy the spectacle without risking their eyesight.
As the countdown to the eclipse continues, the message is clear: securing certified eclipse glasses is a priority, and safety should never be compromised for the sake of witnessing this extraordinary celestial event. With proper precautions and preparations, viewers can safely enjoy what will likely be an unforgettable experience.
