With the UK preparing for its most significant solar eclipse since 1999, high demand has caused a widespread shortage of specialized viewing glasses. Health authorities emphasize that observers must use certified eyewear, as even short-term exposure to the sun can lead to permanent eye damage. Retailers, including the Royal Museums Greenwich, have reported record-breaking orders, leaving many shoppers empty-handed. Some are even scouring local businesses like bakeries that happened to stock the items to secure a pair in time for the event.
Experts warn that standard sunglasses are insufficient, as proper eclipse glasses must meet the ISO 12312-2 safety standard. The Royal College of Ophthalmologists notes that the retina lacks pain receptors, meaning individuals may suffer damage without realizing it immediately. Following the 1999 eclipse, approximately 70 people reported vision issues, many after only brief observation. Due to the high risk and limited supply of safe equipment, officials suggest that indirect viewing methods, such as livestreams, are the safest way to enjoy the phenomenon.
