Eclipse Glasses Are Sold Out Everywhere in the UK — Here's What to Know
UK shops have completely sold out of solar eclipse glasses ahead of the 12 August 2026 partial solar eclipse. Royal Museums Greenwich confirmed it ran out both in its shops and online. The Guardian reported the shortages on 10 August, and the BBC found that specialist eclipse glasses were "all but sold out" across online retailers. The eclipse, described by the BBC as the UK's most significant since 1999, has created huge demand that shops simply could not keep up with.
A solar eclipse happens when the Moon passes between the Earth and the Sun, blocking some or all of the Sun's light. On 12 August 2026, the Moon will completely cover the Sun along a path stretching over the Arctic Ocean, Greenland, Iceland, the Atlantic Ocean, Portugal, and northern Spain, according to the National Solar Observatory. In the UK, though, it will only be a partial eclipse — the Moon covers part of the Sun but not all of it. In London, the eclipse begins at 18:17 BST, reaches its peak at 19:13 BST, and ends shortly after, with the Sun low in the western sky. Across the UK, the peak happens between roughly 19:05 and 19:13 BST, according to BBC Sky at Night Magazine. The UK's last partial solar eclipse, on 25 October 2022, was far less dramatic.
The last big eclipse in the UK was the total eclipse of 11 August 1999, which drew enormous public attention and similar runs on eclipse glasses. The 2026 event will not be a total eclipse for British viewers, but the Sun will be almost 90% covered in northern Scotland, and the late-evening Sun low on the horizon has made it a major focus of public interest. Demand has gone well beyond astronomy shops. A bakery in central London was among the shops selling eclipse glasses, the BBC reported, and a Cornwall tourism expert said the glasses had become a sought-after item there, where eclipse tourism has added to the pressure on supply.
Eclipse glasses cost around £2.99 per pair, according to the Guardian. The Royal Observatory Greenwich told the Guardian it was aware of the shortage and had itself sold out. The UK Health Security Agency (UKHSA) published guidance on 23 July 2026 warning that not all glasses sold online as eclipse glasses meet safety standards. The UKHSA recommended using special eclipse glasses or hand-held solar viewers, and noted that the Sun can also be viewed safely by projection — a simple method where you use a pinhole to cast the Sun's image onto a piece of paper or a wall, so you never look directly at the Sun.
The BBC reported that the safest way to watch the eclipse is using certified eclipse glasses that meet the ISO 12312-2 safety standard, an international rule that ensures the filters protect your eyes from the Sun's harmful rays. The Guardian separately noted that eclipse glasses must be genuine, sold by a reputable retailer, and have specially designed filters. The Independent added a further warning, reporting on fake ISO 12312-2 glasses circulating amid the UK sell-outs.
This creates a real problem: people who cannot find certified glasses through proper shops may turn to unverified online sellers, some of whom are selling counterfeit glasses with fake safety claims.
Some organised viewing events are stepping in to help. The BBC reported on a UK eclipse viewing event planning to give out large numbers of safety-certified eclipse glasses to the public for free. Health officials have also emphasised the projection method as a backup for anyone unable to get certified glasses, since it needs no special equipment at all.
The broader context here is that eclipse demand is very hard for shops to plan for. It spikes in the days just before the event, making it difficult for retailers to know how much stock to carry. Unlike meteor showers, which happen regularly, a solar eclipse visible from a given place is rare enough to cause a one-time surge in buying with no past sales to use as a guide. Shops that stocked glasses on the side — a London bakery, tourism outlets in Cornwall — show that the supply chain stretched well beyond its usual specialist channels, and still came up short. The UKHSA's 23 July guidance came before the worst of the sell-outs, meaning its warning about online sellers is now reaching people in a market where certified options are largely gone.
