I asked an ophthalmologist (My father) about the issue:
He thinks that healthy habits keeps you safe.
As a general rule, try to avoid making too much effort.
• Avoid sitting in a dark room with just the monitor on.
• avoid being too close to the monitor. Distance of one hand length is enough, but not less. (Half of this for your phone).
• Have breaks. After one hour, give your eyes some minutes to refresh.
I personally use dark mode.
- user- 4y agoOne Arm length? One hand length is like 6 inches lol
- lost_tourist 4y agoI think that has to be it. A hand is 4 inches, no?
- aizyuval 4y agoYes! *One arm length.
- Jensson 4y ago> I personally use dark mode. Why? I never use dark mode and never have eye problems. Sometimes sits for like 20 hours coding. All I do is keep the room well lit. I'm in my 30s. I remember having eye straing a few times like a decade ago, but I guess that was from over eating sugar or something. If you have eye strain I'd guess it has some other reason than the screen or how you treat your eyes. Or maybe you need better glasses. Edit: Dark mode would cause your pupils to dilate, maybe that is the reason for the eye strain people here see? Bright room with bright room keeps pupils small and maybe reduces strain.
- blueflow 4y agoRegardless of bright or dark mode, the screen intensity needs to be appropriate for your environment.
- Jensson 4y agoBut we evolved to live during the day. Our eyesight get sharper in darkness thanks to pupil dilation, which mean people would feel it is better to read code in a dark room, but since we evolved to look at things in the sun maybe keeping the pupils dilated and eyesight sharp is the cause of the strain.

- Jensson 4y agoBlood vessels expand when you exercise. So my naive thought is that if blood vessels expand when you use darkmode then that is evidence that you are straining your eyes by looking at darkmode.
- stevebmark 4y agoThe parent comment's advice is good. There are problems with your reply and the replies to it. People are confusing "eye strain" with the long term permanent eye issues of myopia and macular degeneration. "Eye strain" has no long term effects, and there's no such thing as overuse of eye muscles causing soreness. And people confuse all sorts of things, like headaches from neck muscle overuse, with eye strain. Eye dryness is the only real "eye strain" related issue that can have permanent effects. Ironically the advice of "rest your eyes to relax the muscles" might be helpful because it helps your eyes re-wet, as your blink rate lowers when engage in close up activity. The advice itself is based in the nonsense that the muscles can wear out. > I remember having eye strain a few times like a decade ago, but I guess that was from over eating sugar or something No, it wasn't, and I'm always surprised when people look for conclusions like this. Most of the replies in this HN post are anecdotal "here's what I do," and very few have an understanding of the actual issue and question.
- aizyuval 4y agoI personally use dark mode because it’s comfortable. If you keep the room well lit there’s no problem.
