I read either here or on the DJI forum about using the Carson Optical VisorMag available for $11.00 on Amazon. This works perfectly. I also use Poster Putty all the time and simply cut the top mount off the lens, a little putty to the center and PERFECTO. I typically use 1.5 readers, ordered the 1.75x Power (+3.00 Diopters) and problem solved and works.
