Reading glasses

I do have glasses... also for reading, but... I mostly wear it for watching TV.. for far away I can still see quite good. But at work or at home behind pc/laptop I don't see quite well and my regular glasses (build in for reading) sucks.. I have to keep my head in just one way to read it ... that doesn't work for sure. I now bought a very cheap reading glasses to try if that works for the computer and other reading things... Funny.. it costs only 5 euros lol. The glass is cheap too, so that is why it isn't antiglared
