Eye damage?
I feel embarrassed to bring this up, but I have to.
In an at home experiment through distance education, I was instructed to directly combust a tiny fragment of magnesium metal and record the results.
The directions CLEARLY stated multiple times to wear sunglasses, but I forgot. Now I have a tiny aberration in my vision. Because the point of light
from the combustion was very small, the damage to my retina is also small... but it's noticeable.
It sort of looks like the flash you see in your eye after flash photography, except much smaller, and it's not going away. I know that burning Mg
produces UV light.
What kind of healing time should I expect on this? Lesson learned. Sclotomas that form due to staring directly into the Sun for extended periods take
6-12 months to heal, and there is night vision loss in the mean time. I'm guessing this won't take as light?
*sigh*

How big was the Mg? How close were you?
I would think you'd be ok in a few hours. But if it still seems funny in a day or two, book in at an eye specialist.

i don't know if any of us had ever this kind of injury, your wisest option is to get checked by an ophthalmologist, he has the equipment and the
knowledge to help you

If the magnesium burning didn't get into your eyes and your symptoms is only derivative of the burning flash, you might be able to be cured in some
days. What happened to you is the same that occurs with welding operators. With the time and without dark glasses protection they may end up getting
blind. But just one exposition isn't enough to do that at all.
Keep calm. Day by day the flash point in your vision will get smaller and smaller, until you don't notice any symptoms anymore. My advise is to use
saline solution in your eyes a few times a day. It will accelerate your cure.

When I was very young, I ignited a piece of magnalia and after two days that annoying flash point was gone, no lasting damage.

Saline solution could help UV-burned corneas, but I doubt it will have any effect on the retina. I doubt you'll suffer any lasting problems, I've
burned kilos of Mg-turnings over the years without any injury. One time I ignited a full grocery bag sprinkled with sodium chlorate, that one blinded
me completely for 5-10 seconds.

Have you consulted and had an examination by an ophthalmologist? I think that would be a prudent course of action. Although there are certainly many
people on this forum who are knowledgeable of many subjects, I believe you need the services of a licensed professional in ophthalmology (not just
optometry). I think that you should consider most if not all of the replies to your post as just the opinions of concerned people.

To put it in context, burning magnesium ribbon was once used as a camera flash.
But do report back and tell us what the opthamologist says.

Go to a specialist. An opthamologist... Any statement here would be pure conjecture but hey, it could be much worse. It could have been NaOH solution,
direct magnified sunlight, infected Dog shit or ocular herpes (48hrs to seek treatment before possible permenant blindness... my dad was an optom)

Some used magnesium. Some used zirconium. But those flashes last less than a second.
When I was a teen, my chemistry set told me to cut off a small piece of Mg and burn it. The light was intense. The manual did not say to wear glasses
or that a lot of UV light is emitted. (That was back in ~1994)
Anyway, my eyes were fine and are still fine.
