The second thing I do now is to put on the led "headlight" with the elastic bands on my head. I just got it a couple of months ago when I got heavy into fixing the Underwood Noiseless Standard, and I don't know how I managed without it before. It's great!

The head-worn light is a must for me as well. Plus it comes in really handy during power outages. During one outage, I was afraid to type by candlelight because of all the paper strewn about, so I put on the head lamp and opted to type coal miner style instead.
 

I didn't become myopic until I was in my 40s, not long after I transitioned from typewriters to computers as a newspaper reporter and later an editor.
Now that I'm retired, my vision has improved, according to my optometrist, and I think it's from not staring into a computer terminal for 10 hours every day.
Another plus for the old technology of the  typewriter.
If I gave up the internet maybe I wouldn't need glasses at all
 

I am mildly near sighted - been so all my life - and my sweet spot is about the range of a computer screen. So I take my glasses off to use a computer or read ordinary papers or to eat, put them on (bifocals) for distance or fine print. Regarding the "super power" mentioned by some I made a serendipitous discovery: if I wear a pair of reading glasses that is much too strong I also can see really tiny details inches from my nose. So I can sympathize with people who have this power naturally - like wearing a pair of reading glasses much too strong all the time when you don't have your glasses!

There are some disadvantages to having a sweet spot where so many tasks lie - I am always taking off my glasses and sometimes I misplace them, or they fall out of my shirt pocket, and in general they make a nuisance of themselves.
