Input: Text: it's more like today i realized i fucked up by looking at the uv light yesterday.

i'm an embedded software/hardware developer and i was working on a machine that (among other things) sterilizes a sample of blood using 4 very high powered germicidal uv lights in a circle around the container with the blood in it.

normally the machine is closed up and you can't see inside it, and there are interlocks to prevent the machine from operating when it's open but of course i am writing the software and it's easy to bypass them in hardware as well as software.

so over the course of a few hours working on it, i must have managed to get a good dose of uv light in my eyes because when i woke up, opening my eyes was excrutiatingly painful - it felt like the insides of my eyelids were made of sandpaper.

i called a doctor and they told me to get some polysporin eye drops and stay inside with the lights off and the curtains drawn. i had a friend get me the eye drops and what's weird is that i can still see, although it's very, very painful just to open my eyes at all and i am hypersensitive to light. it's started to diminish to the point where i can do more than just lay in bed with my eyes closed, but i spent most of the day shitting myself worrying that i will go permanently blind.

what i have is basically a sunburn on the insides of my eyes on my retina, and i'm lucky that i didn't go blind. this is also apparently what happens when people get snow blindness.

so don't look at uv lights! you will pay for it later even if it seems like there's no harm being done at the moment.
