I got an older style lighted magnifier at a yard sale for $1 years ago. The base which has a 3/8" rod is mounted to the bench and the arching lamp post sits on it. I made bases for my other benches. It uses medium base bulbs. It helps looking at head stamps and for boxer and Berdan primed casings.
My first computer I was looking down at and did fine with the bi and tri lens of my glasses. The new computer sat higher and I had to lean my head back to view the screen. I saw a photo of someone wearing 2 sets of glasses. Thought, got a pair of 200x reading glasses and used them for years, still do when needed.
