As you're near-sighted, ask your optometris to give you a "near vision" prescription. Such prescription would have lenses that are as weak as possible while still allowing you to see clearly at about arm's length.

Idea being that focusing at things close by requires keeping your ciliary muscle stressed for long periods of time (try to focus on your palm as close to your face as possible, and then keep it there for a few minutes to feel this). Focusing at things far away requires complete relaxation of the eye. If you wear near vision glasses, your screen will hopefully be far enough that your eye is relaxed when focusing on it.

I've been using weak glasses for work for the last 5 years or so, and find it makes a huge difference after a day of coding.
