(FILES) US President Donald Trump looks up a the partial solar eclipse with First Lady Melania Trump from the balcony of the White House in Washington, DC, on August 21, 2017. Donald Trump, who on April 8 released a campaign ad of his head blocking out the Sun, famously ignored all safety advice and gazed directly at the eclipse in 2017 when he was in the White House. This election year, President Joe Biden made fun of his rival with a social media post saying "Don't be silly, folks." Health professionals likewise urged people to use certified eclipse glasses to prevent permanent retinal injury. Only those within the totality path could safely remove eye protection for a few precious moments that won't come around again until the next solar eclipse for much of North America, in 2044.
