The father-of-three opened up about his sight in BBC documentary Football, Prince William and Our Mental Health, revealing that his poor vision is actually an asset when it comes to managing anxiety. "My eyesight started to tail off a little bit as I got older, and I didn't used to wear contacts when I was working, so when I gave speeches I couldn't see anyone's face," William said.
"And it helps, because it's just a blur of faces and because you can't see anyone looking at you - I can see enough to read the paper and stuff like that - but I couldn't actually see the whole room. And actually, that really helped with my anxiety," he continued.
Prince William, 41, prefers to wear contact lenses, but there has been the odd occasion where he's stepped out sporting a pair of spectacles - and he certainly suits the Clark Kent aesthetic (if we do say so ourselves). Scroll on to see all the times the Prince of Wales has rocked a pair of glasses in public…
Prince William wore a pair of sporty glasses, or polo goggles, to take part in the Audi Polo Challenge at Coworth Park in 2015.
The father of Prince George, Princess Charlotte and Prince Louis often wears glasses when he's driving, presumably to help enhance his long-distance vision for safety reasons.
Prince William was spotted in the crowd of the Australia v Wales match during the Rugby World Cup 2015 with his wife, Princess Kate. The royal made sure to wear his square spectacles to ensure he didn't miss a single try in the nail-biting match.
The future King doesn't always forgo his contacts when driving, but he did on Christmas Day in 2016 when driving his family through London to attend a lunch at Buckingham Palace hosted by the late Queen Elizabeth II.
Prince William looked especially studious rocking a pair of wire-frame specs to watch the Barclays Premier League match between Blackpool and Wolverhampton Wanderers back in 2010. The then 28-year-old Prince looked cool and casual in an oversized fleece and baseball cap.
Glasses were essential for the Prince to watch the races at the Cheltenham Festival in 2013. Looking dapper in a navy suit, William accessorised with rectangular frame spectacles and a red silk tie.
