White text on black background is hard to read, at least for me as I get a halo effect around text edges due to my astigmatism. However, that is an extreme colour scheme. A more balanced colour scheme like monokai is much better and gives better contrast than a light colour scheme for syntax highlighting, and reduces my eye strain as the monitor isn’t emitting as much white light. I also suffer from floaters, as others here seem too as well, and the main way to make them less distracting / hide them is to use dark colour schemes. My work office, back when I had to go into the office, used overhead LED ‘energy efficient’ lights that were far too bright and had a colour temperature that was too white. They then painted the office walls white, I thought I was entering limbo every morning. I think the key takeaway is that it all comes down to personal taste, and there is no universal colour scheme or brightness level that everyone is comfortable with.
