I use a 43-inch 4K TV as a monitor located about 30 inches from my eyes. I've been using such for at least a decade, and would never return to a tiny porthole facing work of interest (such as a laptop, which is comically unsuited to serious, prolonged use). I do use prescription glasses ground for that working distance and strongly recommend that (prescription lenses). I recently (four weeks ago) had to replace the monitor/TV and spent more than a short while choosing comfortable typeface, font size, and RGB/BGR pixel ordering. As some others have mentioned, if one's eyes are strained, corrections are warranted. I do not deliberately practice frequent distance gazing, but I suspect I do so unconsciously.
