I'd be delighted if my vision just decided to randomly fix itself.
I've had pretty awful vision in my right eye since my pre-teen days, as in those days I was still teaching myself lab techniques (although to this day, I never allow myself to stop learning. The more I read, then go out to the lab and set up an experiment to practise, then the better and more capable I become:))
At the time I was of course, more inexperienced. Was working on a pretty damn simple synthetic procedure, the ring-opening of a certain lactone...which shall remain un-named, but which is often used as a de-bonder for cyanoacrylate glues, and for cleaning alloy wheels.
Boiling hot hydroalcoholic NaOH solution +lactone overheated thanks to adding the caustic too quickly, went up in a mini-vesuvius, and hit me right in the eye.
Ever since, vision in that eye is blurry as hell from anything more than a few feet away.
Managed to irrigate my eye very quickly, within seconds, luckily that night. And both initiate the cleanup, and manage to salvage much product and intermediate lactone, then finish driving my synthesis to completion though before the family awoke. Luckily.
Cleanup wasn't a pleasant task though. The smell of this particular ester is hideous,acrid, akin to putrid, burnt rubber only fouler by far. The big bloody plume of lactone that blasted its way up and out of the condenser used stank to high heaven, and ate away at plastic kitchen fittings wherever it came into contact.
Sod's law-the very moment I took a mere moment to scratch my nose, and re-adjust the fitting of my face mask just had to be the moment the pot decided to exotherm like crazy and go volcanic on me.
