Post-It test

async

There are numerous different issues at play for people here, but this was rather interesting. As I talked about in the other thread, having reflections and overlays helps my eyes actually focus on the text. At times it seems like the eyes doesn't gauge the distance to what should be focused on. I've noticed that there is less strain when the monitor is next to an angled wall as well. Maybe anything that gives the eyes an easy way to gauge the distance is helpful. If that theories hold then a totally frameless monitor floating in space would be horrible.

If you experience text moving around, being hard to focus on, or the colors breaking up. Next time it happens stick a Post-it next to it and see what happens. Interested in if others have the same type of effect.

It seems related to the vergence-accommodation mismatch. For me, possibly related to having a too strong contact lens prescription for a while.

Another test. Focus on some text on the screen til it is sharp, then move your head backwards. Now try the same on some thing else on. For me I seem to have to refocus the monitor text whenever I move, almost manually. No wonder the eyes get strained. Zero problems with the same thing when focusing on physical objects or text.

I've wondered about this too, I've always found glossy screens to be worse than matte. I get this feeling that is harder just the depth of the screen when its shiny. Resolution will also be a factor here, if I can see individual pixels its easier for me to focus on text. There is also the 'screen door' effect of lower resolutions.
