According to a charity called Fight For Sight, 38 per cent of people who’ve been using screens more during lockdown believe their eyesight has deteriorated. I am definitely in that category. This time last year, I didn’t need reading glasses; now I do. When I’m working at my desk this doesn’t much matter, but it has made reading in bed more difficult because I was in the habit of doing this on an iPad under the covers so as not to wake Caroline.
