Biology. I’m in my 50s and get an eye exam every year. According to my optometrist my prescription has been stable for about a decade, but I can definitely tell the difference. My eyes do not focus very fast anymore, my eyes do not adjust going from a light space to a dark space or vice versa very fast anymore. I now have to hold books and my phone away from me to bring them into focus. Same with white text on dark backgrounds. I used to use dark themes for everything, but it just doesn’t work for me anymore. I’ve mentioned these to my optometrist and they say that it happens to everyone with age.
