Light themes are better than dark themes from an eye strain perspective if a room is well lit. On the other hand, dark themes are better in low light conditions, so if you like coding in dark rooms dark themes are essential. Dark themes are also good for photo editing where you don’t want chrome saturating content.

IIRC, the issue is legibility more than eyestrain (though they are related) and light themes are still better with normal vision, but a majority of the adult population has one or more of the vision issues that reverse this (astigmatism being the main one, and alone accounting for nearly 50%.)
