UK's first nationwide solar eclipse of the century sparks safety warnings over fake viewing glasses
A partial solar eclipse will be visible across the whole of the UK on August 12, 2026 — the first this century — prompting warnings over counterfeit glasses and degraded eyewear kept since 1999.

A partial solar eclipse will be visible across the United Kingdom on Wednesday, August 12, 2026 — the first solar eclipse to be seen across the whole of the country this century. The event has prompted safety warnings about counterfeit viewing glasses in circulation, and about old pairs kept since the last comparable eclipse in 1999. The eclipse is expected in the early evening. Reports suggest the Isle of Barra in western Scotland could see about 93% of the Sun obscured, with around 91.4% covered in Glasgow and 90.7% in Edinburgh. Parts of County Kerry in Ireland could see up to 96% to 97% obscured, while the South West of England is tipped for the best views in mainland Britain. The warnings matter because looking at the Sun without proper protection can permanently damage the eyes. Ordinary sunglasses are not enough: specialist solar viewers with an optical density of 5, letting through just one part in 100,000 of incoming light, are the recommended eyewear. Astronomer Jake Foster has cautioned that glasses stored since 1999 may have degraded and should not be relied upon.
The first UK-wide solar eclipse of the century arrives on August 12, 2026
On Wednesday, August 12, 2026, a partial solar eclipse will be visible across the whole of the United Kingdom — the first solar eclipse to be seen from every part of the country this century. Reports have described it as the most dramatic solar eclipse visible from the UK since 1999, when the last comparable event drew millions of viewers outdoors.
The eclipse is expected to take place in the early evening, according to reports, making it an after-work spectacle for much of the country rather than a midday event.
Where viewers stand will shape what they see. The South West of England is expected to enjoy the best views of the eclipse anywhere in mainland Britain, according to reports, with the Moon covering a greater share of the Sun the further west and north the observer. Across the Irish Sea, the south west of Ireland is expected to have that country's finest vantage point.
The event has already prompted a wave of preparation — and caution. Specialist solar eclipse glasses are recommended for anyone planning to look directly at the Sun, and retailers, astronomers and safety campaigners have begun issuing guidance in the months ahead of the date. With counterfeit eyewear in circulation and questions raised about glasses kept since 1999, how viewers protect their eyes has become a story in its own right.
How much of the Sun will disappear, and where
The deepest coverage is expected in Scotland and Ireland, with figures varying considerably by location. According to BBC reporting, the Isle of Barra in western Scotland is expected to see about 93% of the Sun obscured. Glasgow is forecast to see around 91.4% of the Sun covered, and Edinburgh around 90.7%, the broadcaster reported.
Across the Irish Sea, the Irish Mirror reports that up to 96% to 97% of the Sun is expected to be obscured in parts of County Kerry, with the south west of Ireland predicted to have the country's best views of the event.
In England, the South West is expected to offer the best views anywhere in mainland Britain, according to reports. The Sun has reported that the eclipse will give Yorkshire residents their best view of a solar eclipse since 1999, when the last comparable event was visible from the UK.
Precise obscuration figures for most of England, Wales and Northern Ireland have not been reported. Nor have the exact start and end times of the eclipse across different parts of the country, though it is expected to take place in the early evening. How much any given observer actually sees will also depend on weather and visibility conditions on the day, which remain unaddressed in current coverage.
What is clear from the reported figures is that the further north and west the viewer, the more dramatic the eclipse is likely to appear, with the far west of Scotland and south west Ireland closest to a total eclipse experience.
Why ordinary sunglasses will not protect your eyes
Watching a solar eclipse with the naked eye is dangerous. Staring directly at the Sun, even when most of its disc is covered, can damage the eyes, and the harm can be permanent. The temptation is greatest during an eclipse precisely because the Sun looks dimmer than usual, but the radiation reaching the retina remains capable of causing injury.
Ordinary sunglasses are not a solution. However dark their lenses, they are not designed to block the specific radiation that damages the eyes when looking at the Sun, and wearing them can create false confidence. Solar viewers exist for exactly this purpose. They are specialised eyewear engineered for looking directly at the Sun, filtering light to a level that makes direct observation safe.
The standard to look for is an optical density of 5. At that level, only one part in 100,000 of incoming light passes through the lens. That is a far stricter standard than any conventional sunglass lens meets, and it is the threshold that separates protective eclipse eyewear from everything else in a drawer at home.
The distinction matters because the consequences of getting it wrong are invisible at first. The retina has no pain receptors, so damage can occur without any immediate warning. Anyone planning to watch the eclipse should use purpose-made solar viewers rather than improvising with sunglasses or other tinted lenses.
Astronomer Jake Foster warns against digging out glasses from 1999
Anyone tempted to dig out the eclipse glasses they saved from 1999 should think again, according to astronomer Jake Foster. He has warned that eyewear stored since the last comparable eclipse more than two decades ago may have degraded over time, and that relying on it could put viewers' eye health at risk.
The concern is straightforward. Solar viewers are specialised eyewear designed for looking directly at the Sun, and their protective filters must be intact to do the job safely. Glasses that have sat in a drawer, attic or cupboard for 27 years may no longer offer the protection they once did, even if they appear undamaged to the naked eye.
The stakes are high. Proper solar viewing eyewear is expected to have an optical density of 5, allowing only one part in 100,000 of incoming light through. If that filtering has deteriorated, an onlooker staring at the Sun without realising it could be exposed to harmful levels of light, with potentially serious consequences for their vision.
Foster's advice is not to trust glasses dating back to the 1999 eclipse. Viewers planning to watch the August 12, 2026 event should instead ensure the eyewear they use is in good condition and fit for purpose, rather than assuming an old pair will still keep them safe.
Counterfeit glasses are in circulation — how to spot them
Fake and potentially dangerous counterfeit eclipse glasses are already in circulation ahead of the August event, according to reporting by several UK outlets. The concern is that viewers who buy cheap or uncertified eyewear may believe they are protected when they are not, exposing their eyes to harmful solar radiation.
Reports suggest that people planning to watch the eclipse have been advised to check for a specific safety code printed on their glasses before using them. The available reporting does not state which code viewers should look for, but the warning underlines the need to verify that any eyewear meets recognised safety standards rather than assuming it does.
In Scotland, guidance has been published covering both where to obtain safe eclipse glasses and how to identify counterfeit ones, according to the BBC and other publishers. That guidance is aimed at helping buyers distinguish genuine solar viewers from imitation products that may look convincing but fail to filter out dangerous light.
The warnings reflect the scale of public interest in the eclipse, which is expected to draw large numbers of first-time viewers unfamiliar with the risks. Retailers selling uncertified glasses have exploited similar demand around previous eclipses, and the circulation of fakes has prompted consumer safety messaging well in advance of the event itself.
Anyone buying glasses is advised to treat unusually cheap products, or those without clear safety markings, with suspicion, and to source eyewear only through reputable sellers identified in the published guidance.
From 1999 to Weston Shore: how Britain is preparing to watch
Across the country, organised gatherings are taking shape for the evening of August 12, 2026. The most detailed plan so far is at Weston Shore Beach in the south of England, where a viewing event will begin at 19:45. As the partial eclipse draws to a close, attendees will be treated to a sound bath, giving the occasion a distinctly communal, almost ceremonial feel.
The run-up to the eclipse has been long. The last comparable event visible from the UK came in 1999, and some viewers have held on to the glasses they used then. In the months before August 2026, warnings began to appear about counterfeit eclipse glasses in circulation, alongside guidance on how to identify fakes and check for a safety code. Astronomer Jake Foster added a further caution, advising that eyewear stored since 1999 may have degraded and should not be relied upon.
Then comes the event itself. On Wednesday, August 12, 2026, the partial eclipse will unfold in the early evening — the first solar eclipse visible across the whole of the UK this century, and described by some outlets as the most dramatic since 1999. The South West of England is expected to enjoy the best views anywhere in mainland Britain, which helps explain the concentration of events along the southern coast. In Scotland, guidance has been published on where to obtain safe glasses, suggesting organised interest there too.
For many, the Weston Shore gathering will be the moment the wait ends: glasses on, eyes skyward, and the Sun partially swallowed as the sound bath plays out over the beach.
The last comparable solar eclipse visible from the UK occurs; some viewers keep their eclipse glasses from this event, which experts later warn may have degraded.
