All right. What you don't want to do is increase
artificial light intensity. A big part of the issue is the light spectrum and distribution of it. There is a pretty easy way to test / verify this, if you have an eye chart handy. Compare your acuity in outdoor, shaded light, to a solely fluorescent lit environment. Once you get to where you can barely make out the line, note the difference in acuity natural vs. artificial light.
Also, the minus lens creates focal plane stimulus inside the eye that prompts axial elongation. Lots of studies on this subject, it's basically uncontested. What you really don't want to be doing is wear a lens that gives you sharp distance vision, while working up close. You want to have a specific reduced prescription for close-up, that just gives you correction to the distance you need.
Breaks, also. Initial myopia is a ciliary (focusing muscle) spasm. Lots of studies there too, look for pseudo myopia or NITM (near induced transient myopia). Part of your current deficiency is ciliary, part is axial elongation. Take an hour break every three hours. Get outside. Focus at a distance. Your ciliary muscle isn't meant to be all tensed up (close-up use) all day.
