It isn't too bad reading while in portrait mode as the gradient gradually changes from top to bottom, so each line starts and ends within the same color/tint. However, when I turn it into landscape mode it becomes rather problematic as with each line you cover the entire gradient. I like holding the Voyage left handed (I'm a southpaw) in Landscape because the bottom of the bezel is the largest bezel area and provides plenty of room to rest my thumb without touching the screen. But having my eyes constantly going back and forth across the gradient causes eyestrain.
