Phillips Clip-on Flip-up Shade 3.0. Shade 3 is much lighter than shade 5. If you are using didymiums instead of the proper borosilicate glass eye protection and you are not ready to purchase a proper pair, you can use these clip-ons temporarily. Should be replaced periodically.
BoroView 3 (GB3) green poly filter is most often used by people working with Borosilicate Glass. It provides protection from UV, Infrared, and blocks Sodium Flare. Shade 3 is most often chosen by people doing smaller work such as beads/marbles or pendants.
