So far I don't - I am the only one in my family who does not need glasses. To put off reading glasses as long as possible I exercise my eyes; I get close to a window with a screen, and keep shifting focus between the screen and a distant object. I can still focus clearly on objects about 6 inches away. Closer is difficult but sometimes doable with practice. I can clearly discern the pixels on my smartphone (4.99" 1080p display) and huge pixels on my desktop monitors (1080p) drive me nuts. I'm hoping Asus gets their 1440p 120Hz (3D capable!) monitors out soon.
One thing I have noticed is the last couple of years when I get over-tired I cannot focus clearly on anything so there is that.
