I used to prefer dark mode because it reduced all white light. But then I realized that I don't have an issue with white light, just the blue light spectrum in white light.
I have switched to light mode but with a heavy blue light filter and find it much better than dark mode on my eyes.
Did you read the article? It actually points to numerous scientific studies that show that light mode is better.
And by better I mean (from the article):
"Light Mode provides better performance in focusing of the eye, identifying letters, transcribing letters, text comprehension, reading speed, and proofreading performance, and at least some older studies suggest that using a positive polarity display results in less visual fatigue and increased visual comfort."
Now I'm interested to see what their business model is. It seems like they have a lot of money to throw at services instead of developing it themselves, so I'm interested in their ROI or opportunity cost decisions now.
If the money you make is tied the hours you work, probably not. But once you figure out ways to divorce the two you'll probably feel more like you are "killing it."
