Many half-face respirators come with goggles that are not effective in smoke and vapor environments. It's a good idea to purchase goggles separately that...

• Fit around the eyes and provide a good seal above the respirator without interference.
• Are anti-fog and anti-scratch.
• Fit over eyeglasses if you need them. (Alternatively, you might want to get a pair of glasses that will fit within them.)

More on this later!
