Yes, a great idea is to wear safety glasses and I add a blue-blocking light orange tint on my glasses for my late evening work. Works well to enhance restful sleep as any blue light signals your brain & body that it is morning.? Medical papers on the subject of light-triggered circadian cycles are very interesting :-)

This is one of the reason, but not the only one, why I wear tempered-glass reading glasses nearly 24/7. ?

Never, ever shake hot solder off any connection.? When I worked for Motorola, my fellow engr decided to shake the solder off a coax end and solder went in his eye, causing scarring!

The best desoldering strategy for me has been to use some solder wick copper braid to clear excess solder and a pointy stainless probe to dress the hole.? I sharpened the taper on the Aven tip (Aven 20031) for the ideal size.? Having a pair of these probes can be useful when touching solder pads on a crowded PCB with a DVM.
