I had that from grinding in restricted space at an awkward angle - the
sparks got in through the mesh at the side of my goggles. My local A&E

It really isn't all that bad having your eye debrided (a lot less
irritating than having a bit of steel or abrasive embedded in your
cornea) but it's funny how everything appears to wobble around as the
burr chews up pieces of eyeball.
