How to watch the solar eclipse safely this summer
On Wednesday 12 August 2026, a partial solar eclipse will be visible across the UK. It's a rare and exciting event that many people will be keen to watch. But looking directly at the Sun without the right protection can cause permanent damage to your eyesight. Here's how to enjoy the eclipse safely.
On August 12, 2026, a partial solar eclipse will be visible across the UK, a rare event offering an exciting celestial spectacle for many. However, direct exposure to the Sun without proper protection during such an event can lead to severe, irreversible damage to one's eyesight. This article provides guidance on how to enjoy the eclipse safely.
The solar eclipse's visibility across the UK is particularly noteworthy, with the South West region likely to witness the maximum coverage, surpassing the 1999 total solar eclipse that was visible in much of Cornwall and Devon. This makes the 2026 event a truly special occasion, promising clear skies for viewing despite the possibility of cloudy conditions.
The risk in observing a solar eclipse lies in the Sun's diminished brightness, which can trick the eye into remaining open, thereby exposing the retina to intense sunlight. This damage can occur without pain, often going unnoticed until it's too late. Following the 1999 total solar eclipse, the Royal College of Ophthalmologists recorded about 70 cases of vision problems following the phenomenon, with around 40% of those cases resulting from only a brief exposure.
Sunglasses, regardless of their darkness, are not suitable for observing a solar eclipse. They can make the Sun's image appear dimmer, encouraging prolonged viewing while still transmitting harmful radiation to the retina. It is crucial to avoid using regular sunglasses during the eclipse.
To safely observe the eclipse, two methods are recommended: the use of certified eclipse viewers or indirect viewing techniques. Eclipse glasses, meeting the international safety standard ISO 12312-2:2015(E), should be used if opting for eclipse viewers. These glasses can be sourced from reliable retailers, including Royal Museums Greenwich. Certify the product's authenticity before use, as online vendors may not adhere to the required safety standards. Damaged or scratched glasses should be discarded.
Indirect viewing methods offer an alternative without the need for specialized equipment. A pinhole viewer, easily constructed at home, or projecting the Sun's image through a colander, gaps in tree leaves, or using a pinhole projector are safe options. The Royal Astronomical Society provides detailed advice on these methods to ensure safe viewing practices.
