I welded for 15 years and still have a buzz box in the garage. One time I didn't go to the doctor and it took twice as long to get over them.
I got burned so bad one time that I had to wear patches on my eyes for two days. I was welding inside of a SS tank for 12 hours, the reflection got me. After that experience I stuck a cloth over the back of my head. It was completely dark inside my helmet when I welded. After that its straight to the doctor for pain drops and antibiotics anytime I damaged my eyes.
Being blinded for two days was no fun. Protect your eyes us normal people only get two. Superman may get more but I haven't met him.
That was 20 years ago and I pay for it every day, no night vision, head lights blind me. When it rains I may as well stay home after dark.
When I weld now I wear tented glasses as well as a self darkening hood. Never try to weld with just your eyes closed. Even tacking will burn your eyes right through your eye lids.
