Just put the TV further away, it has a similar effect to increasing the DPI, but also it reduces the amount of optical accommodation your eyes need to do (ie eye muscles stretching your lens flatter), which reduces eye strain and must surely reduce progression of myopia. 14 hour days with no eye cramp. I think 4k is starting to approach the upper useful limit of detail you would want on a rectangular monitor that you look at without moving your head, it's a nice bump over 1080p. 1080p upscaled to 4k also looks better than 'raw' 1080p.
- Stratoscope 9y agoThat would work well if you can always use the TV/monitor at a farther distance. This wouldn't be an option for me. Although I do usually work at my home office, I also need to be able to use a laptop on its own when I'm traveling or just want to get out for a while. So that determines the 20" focus distance I need. With single vision prescription glasses tuned for that distance, my eyes don't have to do any of the optical accommodation you mention. My glasses are set up to let my eyes be relaxed at 20"; there's no strain of my eye muscles trying to adjust to a different distance.
- davidzweig 9y agoYes, you need the space. There was a site I was reading some time ago that mentioned with glasses, the geometry of your eyes converging on point nearby (ie slightly 'cross-eyed') doesn't correspond with the eye muscles relaxed, for focusing at 'infinity'. The 'control systems' are likely coupled. I've used glasses with smaller screens, and I've noticed my eyes behaving a bit strange (perhaps seemed harder to focus) when alternating between glasses/no glasses. No idea if there are any other consequences. Maybe it's fine.
