why can you not look at a welding flare with your bare eyes but can look at it on tv without eye protection?

so it’s a combination of the light intensity and the sparks. in person, sparks entering your eye will damage your eye and cause blindness, burns, etc. same with the light intensity. however on tv, who cares, sparks won’t matter. and the light intensity is limited by what the tv can display, and no tv can be so bright that it can damage your eyes. the light intensity only matters if you’re up close in person (ie the welder) since it encompasses a large part of your field of vision. if you’re further away, then you don’t need eye protection since it’s a smaller field of vision and the light intensity drops off significantly.
