I also get headaches and stuff. I'm 42 if that is any use. This year, I've been really busy with work and have been doing a lot of my Christmas shopping and stuff on my iphone. When I'm using my iphone, I have to hold it out at arms length to read what it says otherwise its a big old blur :-S also, I think my eyes are working a lot harder than they should be, because I have to squint to make out fine print otherwise my eyes begin to water. I don't know wether it's just because its Christmas and I'm stressed or I might finally need to invest in a pair of reading glasses :-/
>>> My eyes really hurt when I focus on something close up?
