Yes, it really is. This is due to the fact that during the burning of the welding arc a large amount of ultraviolet radiation is released. What plays a destructive role for the eyes . It is not for nothing that welders, when performing their professional tasks, use welding helmets equipped with light filters .
In total, there are 4 degrees of eye burn by welding . As you might have guessed, just a fourth degree burn is very dangerous by the development of blindness.
In order to "earn" such a burn, you need to look at welding not long, the main thing is to do it very closely, but cook with the electrode.
When the eye is damaged by ultraviolet light of the 4th degree, tissue necrosis is observed in the affected eyes, which means that the tissues of the eyes begin to die off, and the person becomes blind!
More details It is described in this article - What to do if your eyes hurt from welding. Thank you for your attention, your Welding Territory project!
You can go blind for a couple of days. You won't be able to look at welding for a long time, you will catch the so-called "bunny" and you won't want to. This is very unpleasant.
Acute occupational disease is registered in welders - electrophthalmia (from electro ... and ophthalmia), eye damage with a sufficiently long and intense exposure to ultraviolet and other rays during electric or gas welding, filming, etc. It is manifested by hyperemia and conjunctival edema, lacrimation, photophobia, eyelid spasm. When the cornea is damaged, point infiltrates are observed in it - opacities, superficial rejection of the epithelium. Argon impairs vision very strongly.
You can get blind, because a lot of electromagnetic radiation is emitted during welding, especially the harmful ultraviolet radiation, which literally burns out the retina of the eye
