Weird. I have pretty severe astigmatism, but I find dark themes much more comfortable. I'm maybe a bit photosensitive in general though and prefer to have my whole room/environment on the dim side (I especially can't stand bright overhead lights) so it might just be a matter of keeping things consistent.
Same here - I think it’s more photosensitivity than anything else that makes Dark mode better for me.
As for astigmatism - I’d say wearing your glasses so you don’t strain / squint and stress your muscles is probably the best way to avoid strain. I have it pretty bad but it’s stabilized over the years with the right prescription and the correct degrees of rotation.
I believe it's called light phobia. not that I'm afraid of light but I run from bright overbearing light if I can.
I understand light backgrounds may be better if you can handle it but I don't think I'll ever be able to, except when wearing rose tinted glasses I have to block light.
