UK Braces for Partial Solar Eclipse Amid Conflicting Safety Advice
Health officials warn of retinal damage risks as government suggests colander viewing and astronomers claim easier direct observation.

A partial solar eclipse will sweep across the UK on 12 August.
Intense ultraviolet and infrared radiation bombards the retina without immediate pain, leading to solar retinopathy, an irreversible condition.
Safe viewing demands certified eclipse glasses, marked 'ISO 12312-2' or 'ISO 12312-2:2015'; the government advises Britons to use a colander to prevent permanent eye damage.
Astronomers, however, claim the sun will appear darker during the eclipse, making it easier to look at directly. This statement directly contradicts official health warnings.
This will be the most complete solar eclipse visible in the UK since 1999.
The moon passes directly between the sun and Earth, blocking most of its light; London will see about 90 per cent of the sun's light obscured.
The blockage proves even more significant in the South West of the UK, where approximately 95 per cent of the sun's light will be obscured.
Royal Museums Greenwich claims this will be the most complete solar eclipse visible in the UK since 1999. They further state it will be the best visible from the UK and Ireland so far this century.
Despite the significant blockage, Royal Museums Greenwich claims the sky will not become dark as it is not a total eclipse. A noticeable difference in temperature and light levels is expected.
The Royal Observatory will offer a livestream of the event, providing an alternative for those unable to view it directly.
Damage to the retina is not painful, meaning people often do not realize harm is happening until it is too late. Consumers are cautioned about online products that do not meet safety requirements.
The eclipse will conclude for all UK viewers by 8.10pm.
