All of this shows that everyone is different.

I will be turning 60 next month, and as soon as I get my second Moderna shot I'm going to be booking an eye appt to probably spend a ton of money on new glasses for my ever changing eyes.
I have bad eyes, have been wearing glasses since I was two years old, and I have ALWAYS needed/liked lots of light. I exchanged all of my lightbulbs to Daylight, and where tolerated get 100 watt bulbs.
I'm able to read on anything tablet, phone, eink, but my preferred reader is my pc.
Different strokes for different folks.
