I ought to have posted this piece regarding firework injuries on Wednesday to get folks in the mood – but, better late than never!
This is an entertaining little experiment published in JAMA investigating the mechanism of ocular trauma from fireworks. These authors created a setup in which a cadaveric eye was suspended in a network of sensors – and then concussive charges and fireworks were exploded at various distances.
Based on their experiments, these authors conclude most of the ocular injury potential is superficial and results from flying debris, rather from any explosive pressure wave. Fascinating little study!

Eh, while amusing, 10 grams of pyrodex isn't a firecracker. Many are less powerful, some are more powerful.
Yes, the conclusion that flying debris (or projectiles themselves)is what injures eyes is correct.
Even blast literature doesn't talk much about overpressure injury to the eyes. Eardrums, lungs, hollow viscous organs, on the other hand…
