I feel your pain, from the other side. I find non-dark themed apps very hard to use due to my astigmatism and the resulting chromatic aberration (especially for blues) from the glasses. The onset of presbyopia of course doesn't help. Having dark and light themes, and high contrast ones at that, are a huge help for me. I am using the "MiniHack" app on an iPad now in its dark theme, but it is dark gray instead of a solid black background. The ability to change colors also helps. I removed all pure blues from my IDEs/editors, for example. (JetBrains, VIM and Emacs are fortunately all highly configurable.)
