The owner of a post office said she "cannot keep up with the demand" for specialist glasses to view Wednesday's highly-anticipated solar eclipse. Karen Smith, who runs Booker Avenue Post Office in south Liverpool, said she has completely sold out of the specialist glasses after being "inundated" by eclipse enthusiasts. The most dramatic partial solar eclipse so far this century will be visible across the UK on Wednesday evening - peaking in northwest England at 19:10 BST. Experts have warned those without glasses not to look directly at the Sun or use sunglasses, with even brief exposure potentially causing lasting damage - and advises using an indirect viewing method, such as a pinhole camera.
