An eye health charity is recommending people learn the 20-20-20 rule to protect their sight, as lockdown has increased people s time using screens.
Fight for Sight advises looking at something 20 feet away for 20 seconds, every 20 minutes you look at a screen.
Out of 2,000 people, half used screens more since Covid struck and a third (38%) of those believed their eyesight had worsened, a survey suggested.
Opticians remain open for those who need them, the charity said.
The representative survey of 2,000 adults suggested one in five were less likely to get an eye test now than before the pandemic, for fear of catching or spreading the virus.
