A solar eclipse on August 12 will darken up to 95% of the Sun as seen from the United Kingdom, making it the most dramatic eclipse visible from the UK since August 1999. The Moon will slowly slide in front of the Sun, leaving only a thin crescent of light in some areas. Viewers across the UK and Europe will be able to watch the event, but experts stress that looking directly at the Sun without proper protection can cause serious eye damage. Special solar eclipse glasses, which filter out harmful rays, are recommended for safe viewing. These are available in advance or in local stores, and observers should ensure their glasses meet safety standards.
