As with most "medical" discussions online, something like being "good for your body part" rapidly turns into anything other than scientific medical evidence. Much like how its impossible to discuss something like diet scientifically online. The fad aspect should not be overlooked. Originally, "light mode" GUIs on CRTs was something of a fools errand because most CRTs are somewhat non-linear so light mode emphasized waviness and interference patterns and outright astigmatism. Occasionally "light mode" was a bragging point that your hardware could handle it and your GUI was designed to cooperate with the limited hardware of the day (think original 80s 90s apples). Around the turn of the century "light mode" became a financial status symbol that you can afford a "perfect" LCD display, so only the coolest people used light mode. Now, 2010 is too old to be stylish so obviously the opposite of light mode is "dark mode" and that is the pinnacle of style because it proves you're using something designed or redesigned post 2015 or so. Just the usual conspicuous consumption oneupsmanship. Another aspect rarely mentioned is distraction / ADD / working conditions. Obviously dark mode on a glossy screen provides something of a perfect mirror to see your surroundings which is usually distracting to normal people in normal conditions. For those with ADD or easily distracted in a tightly packed open office its practically an ADA issue to force them to use dark mode. If I must have a glossy screen I find it vastly less distracting to use light mode. Turn up the brightness so its not the brightest thing in the room but its brighter than the endlessly moving reflections on the screen and light mode looks pretty good.
