It has an amazingly clear view of the puddle and the automatic darkening is better than perfect.
This lens is awesome. I uses this lens for tig welding ranging from 30 amps to 140 and it's all works the same no difference. It's great for stick welding.
As far as a lens it's the Very Best I've ever seen. I can weld stainless All day with zero eye strain. Highly recommend it. Also being it's Size should it ever break you ca. Sub a fixed shade in a pinch.
Clear, crystal clear.
This is a significant upgrade from my last lens and my last lens wasn't doing the job.
