I have glasses for reading and glasses for driving.
I used to use the reading glasses for my laptop too.
I have new reading glasses that I'm not getting on with at all. There not great for reading documents - one of lenses just seems smudged but is clearly not dirty. I am very conscious of the frames - whereas I wasnt before (and they're the same frames). And they make the text in my laptop illegible.
Have made an appointment with the optician. They are very nice there and not a rip off but she indicated that I probably need a third pair for the laptop.
Do people really have 3 types of glasses? To be honest I'm not happy to be shelling out again after just doing that a few weeks ago but I cant read from my laptop so will have no choice.
