Don't worry, people like the poster below who has no idea how eyes work will tell you you're wrong.
Citysnaps, lets use some critical thinking skills for a moment. What happens when a person dies? Their pupil dilates, because the muscle relaxes. I know the user, who also has no clue what he's talking about that you initially were agreeing with tried to sound all intelligent by claiming constricted pupils were the eyes way of relaxing but he's wrong as well.
There are tons of people on here saying the same thing I am, dark mode helps their eyes. Stop trying to dismiss them.
OK, sounds like you're an expert on eyes, likely a doctor - if it floats your boat by all means embrace dark interfaces. Others know otherwise.
