I know. Me, too!
And my mother used to get on me about doing my homework without being under a very bright light. Then years later I heard the theory that eye strain is caused by bright light and soothed or avoided altogether by using a rather dim light.
And while I'm harping on my poor mother here, she used to chastise me for turning the channel knob on the tv too fast. She said it would wreck the knob. So when I went from channel to channel I had to pause for about three seconds in between. It could take a while since we only got three channels and they were far apart on the knob!
By the way perhaps you are too young to know about this - but back then when you turned the tv off a spot of light would remain in the middle of the screen for what seemed like the longest time. Hah. I just remembered that.
I remember that. We’d watch the picture shrink as the dot got smaller (and brighter/more concentrated).
When we had to turn the tv off we’d wait to “go” until after the dot had disappeared.
