With my struggles, I've found it easier to focus on my computer at work with reading glasses that are just slightly strong. It forces my eyes to stay focused, not necessarily needed for seeing - if that makes any sense.
The prescription is so slight, they are a little harder to find. Typically reading glasses start at +1.25, but I only need +1.00. Found some today at Walmart for cheap, so I bought a purple pair, a blue pair, and a red pair. Why not?
