Protecting your eyes when torchworking is absolutely key. There are a few risks when you begin to work at the torch, such as shattering glass, harmful UV and infrared light, and irritation from sodium flare (also called soda flare). If you decide to work with soft glass, choose a lens that blocks UV light and sodium flare. If you decide to work with borosilicate glass, you will need a lens that offers protection from infrared, UV light, and sodium flare.
