I heard that astigmatism is the reason some people find reading white-on-black intolerable: the edges shift from their proper places, look doubled, this kind of stuff. Idk if astigmatism-correcting glasses fix the problem, as I'm not that diligent with my prescriptions.

Personally, somehow I'm ok with looking at code and some notes in light-gray-on-black, but reading paragraphs of text is immediately off-putting. The proliferation of ‘dark theme’ sites is not working out for me.

Wow so interesting! I have a very high astigmatism so this makes a lot of sense! I wonder if it would help to wear glasses that correct. I wear my contacts and they really aren't capable of correct astigmatism the way glasses are.

A comment elsewhere in the thread explains the mechanism of why light background results in better eye focus: https://news.ycombinator.com/item?id=33403128

Probably relevant with astigmatism, since tighter focus should at least somewhat alleviate the shifty out-of-place edges (hopefully).

Just seeing your comment. Thanks for the link, that was a great comment and helped me to understand something I experience but did not understand the cause of!
