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.
