In mid-2019, an eye-catching advert appeared: "Get 20/20 vision before 2020". It was from a company offering eye surgery, encouraging readers to have the operation before the end of 2019, so that by the beginning of the year 2020 they would have ‘normal vision’. It is now too late to have it before 2020, but doubtless the same business, and others, will continue to offer it in this New Year.
