For those who wear glasses regularly:
I got some clip on lenses that flip up and down. Mine are 4x, but they flip down over the 2x reading glass portion of my bifocals, giving 6x magnification. It's a little too much, and I have to get really close to get it in focus, but once there I can see every tiny detail! I found them at a services for the blind shop. They have a tip jar to help fund the non-profit that runs the shop, and even with a healthy tip, they were not expensive.
There are higher-tech solutions, these are just convenient and cheap. High-power reading glasses would be similar, for those who don't wear regular glasses.
