- llm_trw 3y agoThey absolutely can. Anyone around them for long enough has dead spots in their eyes.

- GuB-42 3y agoNot at all the same risk profile. Arc welding is just a really bright UV light, and without appropriate protection, it will cause what is essentially a sunburn on the surface of the eye. It is painful, but it usually heals in a couple of days. It shouldn't significantly damage the retina. Laser light is different: a laser is effectively a point light source, and it will focus inside the eye to a single point with enough brightness to cause a burn. It can cause a permanent blind spot, and damage may happen faster and be less noticeable at first.

- jfoutz 3y agoyes, but not permanently. You can certainly get dazzled by bright headlights, I can anyway. but laser light, like staring into the sun, will destroy the delicate structure of your retina, and it doesn't grow back.
