Long queues formed outside numerous corner shops across the United Kingdom as residents made a last-minute rush to purchase solar eclipse glasses. Videos shared on social media platforms like TikTok depicted shoppers waiting for hours, with some lines extending for hundreds of meters.
In London, some individuals queued for over three hours to acquire the essential eyewear needed to safely view the astronomical event. One shop reportedly received a delivery of 10,000 pairs of glasses flown in from Heathrow Airport to meet the demand. Prices for the glasses were set at £9.99 per pair, with some customers limited to purchasing a maximum of five.
Eclipse glasses are designed to filter out nearly all of the sun's intense visible, ultraviolet, and infrared light. Experts have warned that ordinary sunglasses, even very dark ones, are insufficient and unsafe for direct solar viewing during an eclipse. Staring at the sun without proper protection can lead to serious and permanent eye damage.
Safety Warnings and Previous Eclipse Glasses
Astronomers and ophthalmologists emphasized the critical importance of using certified eclipse glasses that meet the ISO 12312-2 safety standard. Dr. Greg Brown, an astronomer at the Royal Observatory Greenwich, advised against using glasses from previous solar eclipses, such as the one in 1999, as the protective film can degrade over time, potentially rendering them ineffective and dangerous. Mohamed Elalfy, president of the Royal College of Ophthalmologists, highlighted that retinal damage occurs without pain receptors, with symptoms like blurred vision, blind spots, and reduced color perception only becoming apparent hours later, sometimes resulting in permanent vision loss.
The surge in demand has drawn comparisons to the widespread shortages of toilet paper during the COVID-19 pandemic. Some individuals on online forums expressed resignation, acknowledging the widespread scramble and the difficulty of finding available glasses. Amidst the rush, reports emerged of eclipse glasses being resold online for as much as £400 per pair.
The upcoming solar eclipse is anticipated to draw significant public attention, with many Britons looking skyward for a glimpse of the moon obscuring the sun. The optimal viewing locations in the UK for the eclipse, with percentages of solar coverage, include Bishop Rock in the Isles of Scilly (96.5%), Penzance (95.8%), and Falmouth (95.4%). Major cities like London are expected to experience around 91.4% coverage.
