I would ask a specialist, anyhow here my 2 cents I learned that: * having a lot of space behind your monitor helps a lot: you raise your head and you focus at infinite: this way I relax my eyes (I read about it, it is not just my sensation) * the above works also with your desktop's background image: choose one that let you focus infinite * enable auto dark mode into your laptop (and in your phone) * be 100% sure your graphic card is set well: I am not talking about Mac or Win, of course, but a Linux with maybe a stupid proprietary video card without proper drivers: this is may not the case anymore, but many years ago was a pain to work with Nvidia (I hate it!) and Linux: drivers where not available, and what apparently was working was a real disaster: I even feel sorry for having given my old working laptop to a friend: I still think the anti-aliasing and other setting on chars rendering makes a bit of a difference. * select, of course, dark background and gray chars while coding :) * try the so called "blue led" glasses: I do, but do not really know if it is just a trick to ask more money for your spectacles (btw, you do use spectacles, don't you) * distance from your eyes to the monitor is important waiting for a feedback from others: I am so scared to harm my eyes :)
