Hi Louise,
If you magnify webpages before printing and they’re OK, it does sound like your specs are no longer the right prescription for you.
When did you last have your eyes checked?
A number of years ago, I had laser-surgery to correct my short sightedness. I was told at the time that as I got older (typically when I reached my 50’s) my eyesight would change and I’d almost certainly become long-sighted and need reading-glasses, and my close-up vision would be quite poor.
As predicted, I now require glasses for reading, computer use and close-up vision (…so a totally different prescription to my teenage short sightedness). My long-distance sight is brill, so vision for outdoor stuff etc. is better than it’s been for years .
Just to illustrate that things change for all of us as time goes by !!
