So you jsut have to do the following(it takes hlaf an hour to an hour to get used to these but then it becomes normal):
- take you brightness and contrast down to 50%, no more than that, this will be weird for a while, stick with it.
- scale your DPI up by 1/4(125%) or more, until you feel like you are an old man that needs reading glasses
- make all your fonts larger, don't be affraid to go nuts, you will fine tune the size in short time - this is most important for your editor, use the font for half an hour, then see if different size fits you better. you should end up in the 15-18 range.
- put your monitor at a distance where you can't touch it with your hand when your back is touching the chair and you sin in comfportable position
- use f.lux for later hours, it removes the blue color, no need for glases, it totally works but you also need proepr light source in the room(ie. warm, not white/cold)
- never work in a dark room, always have a light source on, beside the screen itself, more is better but you have to have a solid contrast on the screen so too much light is bad.
- never sit next to a bright window, use drapes or blinds or whatever, always sit in a way that a window is sideways to you, not behind or in front of you
- don't use screen without antireflective coating or have polished plastic, if you have this monstrosity(apple'n'shiet) trow it in the bin and get a new one(dell for example)
this alone will ensure your UX will be good. there are other things for ergo like chair and desk but this is about eyes so there you go.
