People across Scotland have been frantically scrambling to find the right kind of protective eyewear as the UK prepares for the best view of a solar eclipse in nearly three decades. Up to 95% of the Sun will slowly disappear behind the Moon on Wednesday evening, in the most dramatic partial eclipse visible from the UK since August 1999. But most high street stores have sold out of eclipse glasses and online shoppers who track down a pair risk them not being delivered in time. Eclipse glasses offer protection from harmful rays of sunlight as the Sun can damage the retina and lead to vision problems. Legitimate pairs will have safety certification ISO 12312-2 or ISO 12312-2:2015 printed somewhere on the glasses.
