I'm not sure about your condition, but in my case it is astigmatism which probably increased with age (I have myopia since early school). This means that when it is dark, then eye is dilated more but astigmatism causes it to lose focus more that usual. So black text on white background during the day is focused (corrected with glasses) but white text on dark background during the night is unfocused and I strain to read it and eyes hurt a little, same on the road.
