Chemical uses: Keeping certain fumes which would irritate the eyes, away from the eyes. Also if something goes wrong (e.g. acid splashing out of your test tube, it won't burn through your eyes (causing blindness) but it probably w?ll irritate the skin surrounding it (so stay as safe as possible, even with the goggles and gloves etc). Metal uses: For welding, to keep the hazardous light away. Or keeping shards of hot metal away so they don't go in the eyes.
