Upcoming August 12 Solar Eclipse: Safety Risks and Expert Guidance
8/12/2026, 9:21:05 PM
Core Event
On August 12 2026, a partial solar eclipse will cover more than 90 percent of the Sun’s disc across the United Kingdom between 6:17 p.m. and 8:06 p.m. In Greater Manchester the eclipse will begin at 6:13 p.m., reach maximum obscuration at 7:10 p.m., and end at 8:03 p.m. Observers will see a dramatic darkening of the sky, the deepest since the total eclipse of 1999.
Background & Context
The 1999 total eclipse generated a surge of public interest and about 70 recorded cases of retinal damage, with roughly 40 percent of those sufferers having looked at the Sun for less than a minute. Those data underpin current safety campaigns.
On-the-Ground Report
Peter Smith, a Taunton resident, watched the 1999 eclipse with a borrowed welder’s mask, later experiencing flashing lights, headaches and lasting retinal damage. He now urges the public to use proper eye protection for the upcoming eclipse.
Data & Statistics
- 90 percent solar coverage – the most extensive partial eclipse in the UK since 1999.
- ? 70 retinal-injury cases after the 1999 eclipse (Royal College of Ophthalmologists).
- ? 40 percent involved viewing times under one minute.
Official Statements & Responses
- Mohamed Elalfy, consultant ophthalmologist and president of the Royal College of Ophthalmologists, advises indirect viewing—such as live broadcasts—as the safest method. He notes the retina lacks pain receptors, so damage can occur without immediate sensation.
- Kyla Black, director of optical practice at Boots Opticians, cautions parents to be “particularly careful” with children and warns that DIY filters and ordinary sunglasses do not block harmful infrared and ultraviolet radiation. She stresses checking eclipse glasses for damage before use.
- The Royal Observatory Greenwich reiterates that standard sunglasses are insufficient and recommends only ISO 12312-2-certified solar eclipse spectacles.
Why It Matters
Direct observation can cause irreversible retinal injury, including permanent central vision loss. The risk is heightened by the recent scarcity of certified eclipse glasses online and the prevalence of counterfeit products that lack proper safety standards. Using approved filters protects eye health and prevents a repeat of the 1999 injury surge.
Conflicting Reports & Gaps
Retailers report that ISO-certified eclipse glasses have largely disappeared from online marketplaces ahead of the event, creating a gap between recommended safety equipment and consumer availability. No official estimate of counterfeit glasses in circulation has been provided.
Verbatim Quote
- “Make sure it’s got the right protection and filters to stop any damage because any damage you get, it'll never heal.” — Peter Smith
What’s Next
The Royal College of Ophthalmologists and the Royal Observatory Greenwich will continue to issue safety alerts up to the day of the eclipse. Observatories such as the Greenwich Planetarium encourage the public to attend organized viewing events that provide certified filters or live broadcast streams.
