I was discussing with a colleague about using dark-mode vs. light mode and remembered [an article](https://www.linkedin.com/pulse/astigmatism-part-1-starry-effects-olivier-sannier/) arguing that humans vision is more adapted to light-mode rather than dark-mode:

Unfortunately, no reference is provided to support this claim, so I am wondering if this is just an opinion or there are some studies to support this.

[Wikipedia](https://en.wikipedia.org/wiki/Adaptation_(eye)) seems to confirm this somewhat since we are adapting much faster to "light mode" transition than to dark mode one:

Also, [some studies](https://www.nngroup.com/articles/dark-mode/) confirm that working using light mode is on average more efficient than using dark mode:

> 
> light mode won across all dimensions: irrespective of age, the

I am looking for arguments coming from evolutionary biology to confirm (or not) the assumption that human evolution favors light mode.
