UV levels are expected to peak at a “very high” level of eight for the next three days, with the midday sun at its strongest. This is the highest level of UV radiation typically achieved in the UK. The Met Office said people should “avoid being outside during lunchtime” and that wearing a sun hat and sun cream is “essential”. Greg Dewhurst, senior meteorologist at the Met Office, said: “Our advice is – if you can avoid the midday sun at this time of year, it’s preferable to avoid getting burnt – but if you have to be in the sun for any period of time, then it’s a good idea to try to stay in the shade or wear a high-factor sunscreen. “Ultraviolet radiation can damage your eyes just like it damages your skin. They have to be UV protected sunglasses – the cheapest ones usually aren’t. “The wrap just means that the sun doesn’t usually go through the side of the glasses – sports glasses, the cycling glasses that people wear when they’re out and not just designer sunglasses, so there’s no gap in the side of the sunglasses. “It just stops the sun coming in from the side. As long as the nose of the lens rotates and doesn’t have large gaps on the side, that’s the main thing. “People just think, ‘I’m wearing a pair of sunglasses, it’s fine.’
