This year i couldnīt read the lock on my suitcase and read lettres on the screen

After 47 years without glasses i needed them to be able to read.
I was also working on my backup laptop than cause the other was broken.
My new laptop has much better screen, and with better contrast i can read the screen again without glasses

And also took some rest cause when tired first thing that happens is that i see less.
I will look at those blue blocker glasses.
But is it from working behind a screen? Most of my friends already had reading glasses for years, and they don't work with computers.
