About 9 months ago, I suffered from chronic headaches and went and saw my optometrist. He gave me glasses (I can't remember what script at the time). About 4 months ago, I found my glasses weren't working for me as well as they did so I revisited my optometrist, and I had to have my lenses replaced with stronger ones. I now have a script of +2.50. I'm already finding since having my lenses replaces that my eyes are feeling strained again and I'm finding it more difficult to focus.
I've been told I have long-sightedness.
